(1) MIXER INPUTS (1 / 2 / 3 / 4) – Use the se jacks to route

audio signals into the OUTPUT MIXER section via cables with 3.5 mm con nectors. Cha nnel 1 includes a pre -wired, normalle d connection f rom the paramet ric EQ section, s o the PARAMET RIC EQ output can di rectly enter the C hannel 1 signal pat h just before the vo lume slider. If a 3.5 mm connec tor is inserted i nto the MIXER INPUT 1 jack , the EQ output is d isconnected a nd replaced by the inco ming jack signal fr om MIXER INPUT 1.

(2 ) VOLUME SLIDERS – Use these sliders for independent

volume cont rol of each input ch annel.

(3 ) PAN POT – Thes e knobs control eac h channel’s placement

in the stereo eld.

(4 ) LEV EL (1 / 2 / 3 / 4) – Use these k nobs to cut or boos t each

of the PARAME TRIC EQ’s four frequ ency bands.

(5 ) BANDWIDT H – These knobs cont rol the width or

narrown ess of the paraboli c lter curve for e ach frequenc y band. High er values narrow th e curve, while lower v alues produce a wider, gentler parabolic curve.

(6 ) FREQUENC Y – Use these knobs to adj ust the placement

of each EQ lte r around the center va lue shown just above the knob.

(7 ) IN – Use t his input to route ex ternal signals in to

the PARAMET RIC EQ section vi a cables with 3.5 mm connec tors. The IN jack ’s associ ated signal and clip LED s read the inp ut signal level when BY P is selected on th e EQ/BYP sl iding switch. Whe n EQ is selected on t he EQ/BYP sliding sw itch, the LEDs read th e EQ output level.

(8 ) EQ/BYP – This sli ding switch turn s the PARAMETRIC EQ

circuit o n or o. When the switch is i n the BYP position, and the EQ cir cuit is inactiv e, the signal coming in th rough the IN jack wi ll be passed throu gh unaltered to the Channel 1 mixer channel.

(9 ) EQ OUT (1 / 2) – Use th ese parallel outp ut jacks to send

the PARAMET RIC EQ section’s pro cessed signal out f or use elsewher e via cables with 3.5 m m connector. When th e EQ/BYP s witch is in the BYP (byp assed) positio n, the signal coming in th rough the IN jack will b e duplicated at the E Q OUT outputs.

(10) MIX LEVEL – Use t his knob to adjust th e volume of the

STANDARD OSC outp ut before the adju sted signal is then sent to the he adphone LEVEL cont rol and the nal MAS TER VOLUME control.

(11) FREQ (OFF / 220 / 440 / 880) – Th is sliding switch t urns

the onboa rd oscillator (STANDARD OSC ) on or o and chooses the oscillator’s frequency. The oscillator’s output goes to the O UTPUT MIXER sect ion as a pre-wired p arallel connec tion, like an additio nal fth mono ch annel, that is blende d into the mixer sec tion’s output using t he MIX LEVEL control.

(12 ) MASTER VOLUME – Use th is knob to make nal level

adjustments before the mix goes to the MASTER OUTPUTS.

(13 ) MASTER OUTPUT S – Use these outpu ts to send out the

nal mix via s eparate left an d right jacks via c ables with either 3.5 mm o r ¼” connec tors. For a single m ono output, use only th e output labeled L /MONO.

(14) LEVEL (PHONES) – Use t his knob to control t he volume

level for th e PHONES output.

(15) PHONES – This output s ends out the nal mix f or

headphon es with a 1/8” stereo con nector.

Power Connection

The 305 EQ/MIXER/OUTPUT module comes with the required power cabl e for connecti ng to a standard Euro rack power supply system . Follow these step s to connect power to t he module. It is easier to ma ke these connect ions before the m odule has been mounted in to a rack case.

1. Turn the power supp ly or rack case power o  and disconne ct the power cabl e.

2. Insert th e 16-pin co nnector on the po wer cable into the socket on t he power supply or rac k case. The connec tor has a tab that wi ll align with the gap in t he socket, so it can not be inser ted incorrec tly. If the power supply d oes not have a keyed socke t, be sure to orient pi n 1 (-12 V) with the red stripe o n the cable.

3. Insert t he 10-pin connec tor into the socket o n the back of the modul e. The connector ha s a tab that will align wi th the socket for correct orientation.

4. After bot h ends of the power cab le have been securel y attac hed, you may mount the mo dule in a case and tur n on

the power supply.

Installation

The neces sary screws ar e included with th e module for mount ing in a Eurorac k case. Connect t he power cable bef ore mounting.

Dependi ng on the rack case, th ere may be a series of  xed holes spaced 2 HP ap art along the leng th of the case, or a tr ack that allows indi vidual threaded p lates to slide along th e length of the case. The f ree-moving th readed plates allow p recise positi oning of the modu le, but each plate shoul d be positioned in t he approxim ate relation to the mo unting holes in your m odule before attaching the screws.

Hold the mo dule against the Eur orack rails so that e ach of the mounting h oles are aligned wi th a threaded rail o r threaded plate. Att ach the screws par t way to start, w hich will allow small adjustments to the positioning while you get them all aligned. After th e nal position has b een establishe d, tighten the screws d own.
