Once illuminated, there will be a short delay before audio signal output is enabled. During initial power connections, it may illuminate for a brief period. Ground Jumper: For selecting between chassis, isolation or 200 for the internal audio signal ground. Chassis ground is the default setting and ideal for most applications due to the differential input stage. In the rare case there is system noise present after all other installation countermeasures, changing this jumper to ISO or 200 may reduce or eliminate the noise. Z Power Supply Terminal: For +12V battery, chassis ground, remote input and remote output wire connections. A minimum of 18AWG wire is recommended for power and ground connections. Always protect the +12V power wire with a 1-amp fuse. Speaker Level Input Terminal: For left and right channel speaker level (a.k.a. high level) connections to the source. Input signals ranging from 2Vrms to 20Vrms will produce up to 10Vrms RCA output at maximum to minimum gain setting. Dynamic music signal peaks are allowable up to 40Vrms, but will be clipped. Use this input if your source unit does not have RCA outputs. RCA Input Jacks: For left and right channel low level (a.k.a. line level) signal connections to the source unit. These two channels are summed and processed internally in mono. Input signals ranging from 0.5Vrms to 5Vrms will produce up to 10Vrms RCA output at maximum to minimum gain setting. ` Remote Level Control Jack: This RJ45 jack is for connecting the supplied cable to the external level control unit for remote mounting. A standard ethernet cable may also be used. ' RCA Output Jacks: These mono line level outputs are for signal connection to your amplifier(s). Each output is an independent internal circuit, both capable of driving multiple amplifiers simultaneously. Use quality interconnects to ensure stable connection and minimize the possibility for induced noise. " Mounting Tabs: These mounting tabs are pre-attached and should be used to properly secure the bassFREQ during installation with screws or cable ties. They are removable if the unit can be safely secured by another method. https://manual-hub.com/ 2 Installation & System Wiring It is important to read this manual thoroughly before starting your installation and always plan accordingly. Before installing any Wvtech product, disconnect the negative (ground) wire from the vehicle's battery to avoid damage to the vehicle or yourself. Following all guidelines will help provide years of enjoyment with your Wvtech bassFREQ audio interface. Ground Connection (GND): The GND terminal must be connected to a metal part of the vehicle that is welded to the vehicle body with ground plane back to the main battery ground attachment point (a.k.a. chassis ground). This wire should be a minimum of 18AWG and as short as possible to minimize potential for noise to enter the system. The chassis ground connection point should have all of the paint removed and be scuffed to the bare metal. The ground wire should be terminated by a ground specific interlocking terminal such as the EARL terminal or ring terminal securely bolted to the vehicle with star or lock washer and nut to prevent from coming loose. Avoid using factory ground points to reduce the chance of induced noise from other components. Power Connection (+12V): The constant power connection should be made at the vehicle battery when possible. For direct battery connection, a 1-amp fuse must be installed in-line with the power wire within 18"of the battery and securely connected to the positive battery terminal bolt with a ring terminal. If connecting to another available constant +12V power source, a 1-amp in-line fuse must be added at the connection point. The power wire should be a minimum of 18AWG. Do not install the fuse until all other system connections have been made. Speaker Level Input (SPK): Connect the speaker wires from the source unit to corresponding terminals on the interface. Use the SPK input if your source unit is not equipped with RCA outputs. Always ensure the correct polarity of each channel when making these connections, as failure to do so can severely effect sound performance. Remote Input (REM IN): If the source unit has a remote output wire (provides +12V only when turned on), connect it to the REM IN terminal. If a remote lead is unavailable, all Wvtech interfaces are also enabled with an automatic turn-on circuit that detects audio signal via RCA or SPK inputs, and DC-offset from SPK inputs. While auto turn-on will work in most applications, there may be some cases were detection level is not satisfactory and +12V trigger to REM IN may be required. Remote Output (REM OUT): Use the remote output to provide a +12V trigger to turn on amplifiers or other components. This +12V output is generated internally by the interface when turned on either by REM IN or automatic sensing, and will provide over 500mA of constant current for external devices. System Examples Example-1: Speaker Level Input from OEM Radio GND +12V RCA OUT SPK IN RLC REM OUT Note: When using a receiver's internal power IC to drive speakers directly, note that its speaker outputs will likely clip below the maximum master volume level. Adjust gain settings accordingly for optimum unclipped volume range. Example-2: Speaker Level Input from OEM Amplifier GND +12V RCA OUT SPK IN RLC REM OUT Note: In vehicles where the factory radio has a fixed level or digital output to a factory amplifier, signal for the bassFREQ's speaker level input should be connected at the amplifier's output. 3 https://manual-hub.com/ Example-3: RCA Input from Aftermarket Radio +12V REM IN RLC GND REM OUT RCA IN RCA OUT Note: Other devices such as smartphones or MP3 players may also be used as the main system source via the RCA input, which typically produce 1Vrms output or less. While the bassFREQ's auto turn-on circuit will detect very low signal levels, it may be necessary in some cases to adjust gain for reasonable listening levels but with reduced master volume range. Top Panel Adjustments Z ' OE ` " " OE Clipping Indicator: This yellow LED indicates when the output signal is at maximum level before distortion (clipping) occurs. It will be dimly lit at onset of clipping, and full bright under hard clipping. If the connected amplifier(s) input can handle full 10Vrms output from the bassFREQ, then the gain is set correctly when source unit is at its maximum unclipped volume and this LED is just starting to flicker. It is likely, however, that gain will need to be reduced to match your amplifier(s) maximum input capability or optimize source volume range and desired output vs main full-range speakers. Gain Adjustment: Gain adjustment is for matching the output signal level of the bassFREQ with the maximum unclipped signal range provided by your source and the maximum input capability of your amplifier(s). Follow proper gain setting procedures to ensure optimum source volume range with minimum chance for clipping at any point in the signal chain. Gain will likely need to be adjusted again after all equalizaton and crossovers have been set. Aside from music, a 50Hz -10dBfs signal tone or frequency sweep may be used between the chosen crossover points during the tuning process to ensure proper headroom and gain overlap for typical music recording levels. Z Parametric EQ: This section provides full adjustment for all parameters of a single EQ band, including boost, width and frequency. Unlike traditional bass boost, a parametric EQ provides the tuning flexibility required for differences between vehicles, subwoofers and enclosures. Boost: Provides adjustment for the amount of boost at the center frequency (Fc) set for the parametric EQ band, up to +12dB. If gain has already been adjusted, adding boost may Fc cause the output to clip and require reduction of gain to achieve final desired unclipped output level. Width: Also known as Q, this adjustment sets the 3dB BW = F2-F1 Boost (dB) bandwidth (BW) of the parametric EQ band. A wide setting will include more adjacent frequencies for a broad boost, while a narrow setting will only boost frequencies close to the chosen center frequency (Fc). The range of Q adjustment is 1.5 (wide) to 5 (narrow). To calculate the range of frequencies boosted between the -3dB points of the EQ band, use the formula BW = Fc/Q. F1 F2 Freq (Hz) ð Example: If freqency is set at Fc = 50Hz, and width is set at narrow (Q=5), then the boosted bandwidth will be 50Hz/5 = 10Hz, meaning -3dB at 45Hz and 55Hz. ` Frequency: This adjustment is for setting the center frequency (Fc) of the parametric EQ band, between 30Hz and 80Hz. https://manual-hub.com/ 4 ' Crossover: This section is for selecting the cut-off frequencies for the low-pass filter (LPF) and subsonic filter (a.k.a. infrasonic or high-pass). " Subsonic: Provides adjustment of the lower cut-off point, below which all frequencies are filtered out at -24dB/Oct. Very low freqencies can waste amplifier power and damage subwoofers. This adjustment is especially important for ported enclosures to prevent over-excursion below the tuning frequency. " LPF: This low-pass filter adjustment sets the upper cut-off point, above which all freqencies are filtered out at -24dB/Oct. Unwanted high frequencies allowed to come through subwoofers can cause boomy, buzzy bass that is easy to localize. With a steep -24dB per octave slope, the cut-off frequency can be set higher, allowing more punch with less distortion and optimum integration with main full-range speakers for up-front bass. Notes: The subsonic and low-pass filter stages are at the end of the internal circuit signal chain so that any overlapping frequencies from the parametric EQ will still be filtered at the set crossover points. Setting the subsonic and low-pass filter cut-off points too close together will allow only a very narrow frequency range to pass and will result in reduced output.
