Install the 4 feet at the bottom of the unit using the Philips head #6-32x3/8 screws and feet (included in the accessories). 1.4 RACK MOUNT SETUP The MDX-12 can also be installed in a standard 17" rack. To install the rackmount brackets, temporarily remove the 4 screws on the side/front of the unit using the T10 Torx bit included in the accessories. Attach the brackets by re-using the same screws as shown below for the left side. Do the same for the right side. Note that the left and right brackets are different ensure that the ears are flush with the top and bottom of the unit as shown below. 2 CONNECTIONS AND OPERATION 2.1 INPUT CONNECTIONS Each zone has dedicated RCA L/R jacks, and 2 global inputs can also be selected (RCA 7 and RCA 8). The global inputs BUSS ANALOG INPUTS 7 and 8 also have a second set of output RCA jacks to avoid using an external Y-adapter. 2.2 SOURCE SELECTION The desired source is selected by setting the INPUT switch in the proper position. Position 7 and 8 correspond to the global inputs. 2.3 VOLUME Each zone has a dedicated volume control. Adjust the volume to the desired level using your finger or a small flat screwdriver. When the slot is at the 10:30 position, the amplifier will have approximately 30 dB of gain. 3 2.4 SPEAKER CONNECTIONS Depending on the input signal level, the voltage at the outputs can be high enough to cause electric shock be sure that power is turned off when connecting or disconnecting anything. Also, be sure that the speakers are rated for use with this amplifier an overdriven speaker can pose a fire hazard. You can configure each zone to operate either in single-ended or bridge mode. Bridge mode doubles the output voltage but allows only one speaker to be driven. Single-ended mode is enabled by setting the BRIDGE mode to OFF (lower position). Bridge mode is enabled by setting it to the ON position (upper position). When configured in bridge mode, you only need to connect the right input. Connect your speakers using the MDX-12 detachable terminal block and a small flat screwdriver. For single-ended operation, ensure that your speakers' polarity matches the +/- signs shown on the L/R terminal block. For bridge mode operation, connect the speaker terminal to the L- position and the speaker + terminal to the R+ position. The other 2 positions are unused. 4 2.5 ON MODES The three-way switch located on the rear panel lets you set how the amplifier turns on and off. Once set to the desired mode of operation and all other connections made, connect the power cord of the amplifier to the wall outlet. ON When in this position, the amplifier is always on. AUTO Auto (or Auto-On) turns the amplifier on when it senses an input signal (> -60 dBV or 1 mVrms) and switches off approximately 20 minutes after the input signal stops. When in Auto mode, the trigger input is also monitored, and the unit will turn on if a voltage is detected. TRIG Trig (or Trigger-On) allows the amplifier to be turned on or off remotely via the trigger input. To use Trigger-On, connect a standard 3.5mm (1/8") mono cable between the MDX-12 and the preamplifier or control component. When the mini-jack IN receives power (5-24 volts DC or AC) from an upstream component or system controller, the amplifier will turn on. When the voltage drops to 0V, the amplifier will turn off. The same trigger signal can be linked to trigger inputs on other units through the TRIG LOOP jack. Note that trigger operation also works when the operating mode switch is set to Auto. Ground Trig Signal (5-24 VDC/VAC) 2.6 CHASSIS GROUND The MDX-12 is powered using a double-insulated power cord and, therefore does not have an earth-ground connection to avoid hum. If an earth-ground connection is required, or if connecting to another chassis ground, you can connect a wire using the thumbscrew. 5 2.7 FRONT PANEL POWER MDX-12 1 2 3 4 5 6 POWER LED This LED turns blue when the amplifier is operating normally.
