A simple, practical rule-of-thumb is to use one subwoofer for every two top loudspeakers deployed. The simplest setup consists of placing a single subwoofer between a pair of loudspeakers. For practical reasons, it is often necessary to place the subwoofer on one side, which will usually also produce satisfactory results. Placing subwoofers to the left and right sides of a stage is often convenient, but it tends to create a concentration of low frequency energy in the middle of the audience area (often named "Power Alley"). To prevent this, try clustering all subwoofers in the left/right middle of the stage, or spread them evenly across the front of the stage. Cardioid Configurations Two or more LS118 active subwoofers can be arranged and configured to produce a cardioid radiation pattern very simply, with no complex calculations or processing settings required. The processing necessary for cardioid operation is already programmed into each LS118 unit's DSP. On each subwoofer facing forward (toward the audience), select FORWARD on the Cardioid menu. On each subwoofer facing away from the audience, select REAR on the Cardioid menu. Put the same audio signal into both subwoofers and set the same gain on each one. Back-to-Back Deploying subwoofers for cardioid performance offers 15 dB of sound attenuation to the rear. Figure 2 is a top view of two LS118 active subwoofers oriented vertically and placed back-to-back. Figure 3 also is a top view of a back-to-back arrangement, but with the subwoofers oriented horizontally. Cardioid > Rear Cardioid > Forward Cardioid > Rear -- Figure 2 -- Cardioid > Forward -- Figure 3 -- 8 Stacked Stacking two LS118 active subwoofers is similar to the side-byside arrangement. Place the rear-facing subwoofer on the bottom. Side-by-Side Placing the LS118 active subwoofers side-by-side may save space. ACTIVE SUBWOOFER Cardioid > Forward Front View (as seen from the audience) Cardioid > Rear Floor -- Figure 4 -- Cardioid > Forward Top View Toward Audience Cardioid > Rear -- Figure 5 -- 9 Three-Box Cardioid Systems A three-box array, with two forward-facing subwoofers and one rear-facing subwoofer, gives additional acoustic output to the front but with slightly less optimal rear attenuation. Figure 6 is a top view of a back-to-back three-box array. Figure 7 is a front view of a stacked three-box array. Use the bottom subwoofer as the rear-facing one.

DO NOT attempt to suspend additional loudspeakers or subwoofers underneath the LS118 subwoofer. The LS118 has M10 bolt points on both the top and the sides of the subwoofer and can be deployed in either direction, based on the space or visual requirements of the installation. 1. Use a 6 mm hex key to remove the four hex screws from the four LS118 M10 installation points on the top or side of the subwoofer. 2. Thread an eye bolt into each of the threaded inserts. 3. Tighten the eye bolts until their shoulders are snug against the enclosure. 4. Continue to rotate the eye bolts until they reach the desired position. Do not over-tighten, as that may damage the eye bolt thread or the threaded insert. 5. The subwoofer is ready for suspension. -- Figure 8 -- 13 LS118 Rear Panel 11 12 13 14 1 3 2 4 5 10 7 6 89 -- Figure 9 -- 1. Full color screen displays Menus and Settings 2.

Variable speed ventilation fan 14 System Power The LS118 power module does not include a power switch. This is done to prevent an array from being suspended and a loudspeakers'/subwoofers' power switch inadvertently bumped or left in the off position. To power a subwoofer on/off, either switch the AC supply at the source or twist the AC POWER-IN connector clockwise or counter-clockwise to power each subwoofer on/off. For safety reasons, it is important to follow the proper power cable connection/disconnection sequence to power on or off loudspeakers and subwoofers. Proper power on/off sequencing can help to prevent undesirable sounds from being introduced into the loudspeaker/subwoofer system (pops, clicks, thumps). Always follow the rule that loudspeakers/subwoofers are "last on, first off." WARNING!: The LS118 employs a universal power supply capable of operating the system with input AC power voltages ranging from 100 240 VAC at 50 60 Hz. Make sure to only use the power cable that is appropriate for the location of deployment. AC Connectors The LS118 Subwoofer features dual powerCON TRUE1 AC connectors to support daisy-chaining multiple loudspeakers/subwoofers within an array or for ground-stacking deployments. Neutrik powerCON TRUE1 AC connectors have become standard in the AV production industry and are often found on lighting systems and portable LED walls. PowerCON TRUE1 connector benefits: · 16 Amp current capacity · Safe connection/disconnection under load · POWER-IN and POWER-OUT locking connectors can couple to create extension cables -- without the need for a separate barrel connector · IP65 rating for ingress protection (once coupled) ACTIVE SUBWOOFER Connecting to AC Mains 1. Insert the locking POWER-IN cable connector of the supplied power cable into the INLET connector on the rear panel. 2. Twist the cable connector clockwise until it locks in place. Twisting the connector also turns power on/off for that box (and any subsequent daisy-chained boxes). 3. Plug the other end of the power cable into the appropriate AC Mains power source. 4. Array will power on automatically once the AC Mains power has been connected. PowerCON TRUE1 AC connectors -- Figure 10 -- 15 Daisy Chaining using Power Cable Jumpers The LS118 subwoofer features loop-through power connection using powerCON TRUE1 connectors. The powerCON TRUE1 cable and connector system is rated for a maximum current draw of 16 amps. In most countries, this is sufficient to power a maximum of three (3) LS118 subwoofers from a single connection to the AC mains supply (see chart below for more details by country voltage). When not in use, the powerCON INLETS and OUTLETS connectors located on the subwoofers' rear panel should be covered by the weather-resistant flaps. Neutrik powerCON TRUE1 loop-through cables are not included with LS118 subwoofers but may be purchased separately from most professional audio equipment suppliers or from QSC. · LS-KIT-J (International Jumper Kit: includes 2x 120 cm PowerCON jumpers and 2x 120 cm EtherCON jumpers, 1.5 mm2/H05VV cables) · LA-KIT-J-NA (North America Jumper Kit: includes 2x 48-in PowerCON jumpers and 2x 48-in EtherCON jumpers, 12 AWG/SVT cables NEC compliant) WARNING!: The amplifier AC mains power is present in the loopthrough cables. If the AC mains is connected to one LS118 subwoofer, electrical power is present on all connected loop-through cables. WARNING!: Do not connect more than four (4) LS118 subwoofers together using the jumper power cables (one AC mains power cord and three jumper cables). When using jumper power cables, make all loop-through connections prior to connecting to the AC mains. Weather-resistant flaps Daisy Chaining 1. Insert the locking POWER-OUT connector of the jumper cable (not included) fully into the OUTLET connector on the rear panel. Twist clockwise until it locks in place. -- Figure 11 -- 2. Insert the locking POWER-IN connector into the INLET connector on the rear panel of the next loudspeaker/subwoofer in the chain. Twist clockwise until it locks in place. 3. Repeat until all subwoofers in the array (up to four, using three loop-through jumper cables) are properly connected. Please follow the table below for safely powering each array: Model LS118 Input Current (normal use) 100V = 3.7A 120 V = 3.1A 220~240V = 1.8A 100V (15A circuit) Up to 3x subwoofers Total 11A 220~140V (10A circuit) Up to 4x subwoofers Total 7.2A WARNING!: Always ensure there is 20% headroom when daisy-chaining AC power to multiple boxes. For example, never load more than 12 Amps on a 120 V/15 A circuit, or 8 Amps on an 230 V/10 A circuit. Power On Sequence 1. Turn down the output levels on the mixer (or other audio source) to its minimum position. 2. Switch on all source devices (CD players, mixers, instruments). 3. Apply power to the LS118 subwoofer last, twisting the locking POWER-IN connector clockwise. If the LS118 subwoofers are daisychained to other boxes, then power only needs to be applied to the first box in the chain. 4. Verify that power has been applied to each loudspeaker/subwoofer. When a unit powers on, the yellow STANDBY indicator LED and the red LIMIT indicator LED on the rear panel illuminates. After a few seconds, the red LIMIT indicator and the yellow STANDBY LEDs dim, and the blue POWER indicator LED illuminates. 16 Power Off Sequence 1. Turn down the output levels on the mixer (or other audio source) to its minimum position. 2. Disconnect power to the LS118 subwoofer first, twisting the locking POWER-IN connector counter-clockwise. If the LS118 subwoofers are daisy-chained to other boxes, power only needs to be disconnected from the first box in the chain. 3. Verify that power connections have been disconnected on each box. When the blue POWER indicator LED and yellow Standby LED are no longer illuminated, it is safe to proceed. 4. Power off all audio source devices. Audio Connections NOTE: While digital audio and analog audio can be physically connected simultaneously, the subwoofer will default to digital audio if a Dante® audio connection is made, rendering the analog audio inputs muted until the Dante® signal is disconnected. The analog connections can be used alongside a line array that is ethernet connected for QSC SysNavTM control, as standalone without SysNav control, or as a backup audio connection in the event of digital audio failure. Analog Audio Each subwoofer features a LINE IN (input) XLR and a LINE OUT (output) XLR to support daisychaining multiple loudspeakers/subwoofers in an array. The LINE OUT XLR connector is wired in parallel to the LINE IN XLR connector, making it a direct passthrough. It does not output any Post-DSP signal, nor is the level on the LINE OUT affected by the digital GAIN setting adjusted on the subwoofer. Using the XLR connectors, subwoofers can be safely daisy-chained up to any combination of eight (8) subwoofers or top boxes without any signal loss. LINE IN LINE OUT -- Figure 12 -- NOTE: It is not recommended to use unbalanced audio connections with LS118 subwoofers. Always use XLR balanced audio connections and wiring as shown in Figure 13. Daisy Chaining using Balanced XLR Jumper Cables 1. Connect the audio source (such as a mixing console) to the LINE IN XLR connector (6) on the rear panel. -- Figure 13 -- 2. If daisy-chaining additional boxes in the array, connect the audio loop-through jumper cable (not supplied) from the LINE OUT XLR connector to the LINE IN XLR connector on the next loudspeaker/subwoofer. 3. Continue this process until all loudspeakers/subwoofers in the array are connected using balanced XLR cables. Network The dual network connectors also support daisy-chaining multiple loudspeakers/subwoofers in an array. Unlike the powerCON and XLR connectors which have dedicated input and throughput connectors, the network ports are identical switched ethernet ports, which means either can be used as an input or as a network hop to the next box in the array. The network ports can accept a rugged etherCON connector or a standard RJ45 connector; however, etherCON type connectors are recommended, rather than conventional RJ45 connectors, as the mechanical robustness and EMC performance is superior. Each subwoofer includes two IP addresses, one dedicated for Control and one dedicated for Dante audio-over-IP; however, both Control and Dante data traffic are carried over a single CAT5/6 cable into a single RJ45 port. 17 Daisy Chaining using Network Jumper Cables There are two common methods for connecting network devices: a. Star Topology: In this method, each device has its own port on an ethernet switch. This is the most robust method, but it requires a cable home run from each device back to the ethernet switch, which is suitable for permanent installations but challenging for temporary deployments. b. Daisy-Chaining: This method requires dual switched ports on each device, as found on the L Class loudspeakers and subwoofers. While daisy-chaining is much easier to deploy, it should be noted that each "hop" incurs a latency penalty, measured in microseconds that quickly add up. Therefore, a pre-determined latency is applied to each Dante receiving device to account for switch hops, eliminating the risk of dropped packets and resulting audio glitches. The Dante latency settings are based on worst case latency assumptions and are therefore conservative. The L Class loudspeakers/ subwoofers default to 1 ms which will accommodate up to 10 switch hops. As a reference point, a Dante mixer connected through an ethernet switch to a 6-box daisy-chained array of LS118 subwoofers, is the equivalent of 6 switch hops. If there are 5 switch hops or fewer, there is the potential to adjust the latency down from 1 ms to 0.5 ms, using the Dante Controller software. Please refer to Audinate for more information on Dante Controllers. For ethernet daisy-chaining, the optional LS-KIT-J or LS-KIT-J-NA jumper kit will need to be ordered (refer to the Accessories section for more information). Connecting to a Network 1. Connect the network source (router, switch or computer) to the RJ45 jack on the rear panel using a CAT5/6 cable (not supplied) 2. If using the RJ45 loop-through connections, connect another CAT6 cable to the available RJ45 port on the first loudspeaker/subwoofer, and connect the open-end connector to the RJ45 input on the next loudspeaker/subwoofer. 3. Continue this process until all loudspeakers/subwoofers in the array are connected using RJ45 digital connections. -- Figure 14 -- 18 Control There are two modes of operation using network control: a. Indirect Mode: This mode duplicates functionality of the Rear User Interface (RUI), allowing Ethernet connection to just one box. Low data communication to the other boxes is managed via wireless transmission (QSC AWARETM). NOTE: Do NOT use Indirect Mode for Firmware updates. b. Direct mode: This mode offers greater functionality, but it requires Ethernet connection to every box in the array. When all boxes in the array are discovered on the network, Indirect mode is disabled. To update Firmware, there must be Ethernet connections to each box. An Array can be controlled and monitored using one of two software applications: a. QSC SysNavTM (System Navigator): This Windows application is available from QSC.com and allows the user to discover, control, and monitor each loudspeaker/subwoofer within the array. SysNav also manages Firmware updates. b. QSC Q-SYS DesignerTM: This Windows application is available from QSC.com and allows the user to discover, control, and monitor each loudspeaker/subwoofer within the array. NOTE: Q-SYS Designer requires a Q-SYS Core to fully function. More information on Q-SYS Designer is available from the online Helpfile https://q-syshelp.qsc.com/ Dante Each array of loudspeakers/subwoofers can subscribe to a Dante audio-over-IP Transmitter (TX), sent over the network from common audio sources such as a digital mixing console or a QSC Q-SYS Core. Dante subscriptions can be set up using one of two methods: a. QSC SysNavTM (System Navigator): This Windows application is available from QSC.com and allows the user to view all Dante Transmitters (TX) discovered on the network and subscribe a loudspeaker/subwoofer (or an array) to that transmitter. b. Dante Controller: This Windows or macOS application is available from Audinate.com and provides users with a more advanced tool to managing Dante traffic. 19 LS118 Rear Panel User Interface Navigation When first unpacking the LS118 active subwoofer, make sure to download the latest subwoofer firmware as well as the latest version of the QSC SysNavTM (System navigator) App from QSC.com.
