ENGLISH ™ RQ 4300 SERIES Reference Quality Recording and Sound Reinforcement Console INTRODUCTION Thank you for purchasing the RQ 4300 Series mixing console. The RQ 4300 represents years of experience in mixer engineering and offers incredible versatility through its flexible 13-bus design. Its impressive 4 SUB GROUPS, 6 AUX, L/R and MONO outputs place the RQ 4300 in a league of its own. Additionally, each SUB group features a high-quality dynamic compressor that can be used on the correspondin

PFL – PRE-FADER LISTEN. PFLs send signals to the headphone output and are not affected by the fader setting. AFL – AFTER-FADER LISTEN. AFLs send signals to the headphone output and are affected by fader setting. LOW CUT – (channel low cut). These adjust the frequency in the channel where the low frequencies begin to roll off, and are variable by frequency from OFF (inaudible) to 300 Hz. 1/2, 3/4, L/R, MONO – These buttons route the channels to their respective output buses. BAL/PAN determines 1

STANDARD CHANNELS [CHANNELS 1 — 20 (RQ 4324) AND 1 — 28 (RQ 4332)] REAR PANEL CONNECTIONS (1) INSERT This jack is a 1/4" Tip/Ring/Sleeve (TRS) connection that allows a pre-EQ, pre-fader TIP=SEND RING=RETURN SLEEVE=GROUND) signal to be taken from and returned to the 3 2 1 channel. Insert jacks are often used to route an input signal to an external signal processor.

LED in the MONO MASTER section (45) will blink to indicate that the signal on the MONO LED display and at the headphone out is PFL. Selecting PFL allows the operator to monitor a channel even with the channel muted, and is especially useful for cueing CDs/tapes. When the PFL button is in the out position, the yellow channel LED will blink as an indication of signal presence (-20 dBu). (16) CHANNEL FADER This control varies the signal level sent from the channel to the L/R, SUB, and/or MONO ma

MASTER SECTION FEATURES AND CONTROLS AUX SENDS (21) LEVEL This control sets the output level of the various AUX mixes and is adjustable from no output (– ∞) to +10 dB. (22) MUTE SWITCH/MUTE-CLIPLED This switch mutes the output signal from the respective AUX SEND. Illumination of the corresponding red LED signifies this status. When the MUTE switch is disengaged, the LED functions as a clip (PK) indicator that will illuminate at 2 dB below clipping. (23) AFLSWITCH/AFL-SIGNALLED This switch dir

NOTE: While linked, the gain reduction meter in the second group may show gain reduction, although it is not a true representation of the compressor activity. (27) GAIN REDUCTION LED’s These LEDs graphically show the amount of gain being reduced through compression (-1 to –12 dB). (28) THRESHOLD This control sets the level at which compression activates and is variable from –30 dBu to no compression in the OFF position. The adjacent LED (0 dBu) will illuminate when enough signal is present fo

(36) 1/2, 3/4, L/R, MONO (ASSIGN) Like the channel assign switches, these buttons determine the bus assignment of the input signal. They determine where the return signal is being sent. (37) BAL/PAN This control determines the placement of the signal in its assigned bus. Rotating the control counterclockwise (L) sends more signal to the LEFT output and odd-numbered SUBS; rotating clockwise (R) sends more signal to the RIGHT output and even-numbered SUBS. The C position sends equal amounts to eac

switch allows a post-fader signal to be sent to the HEADPHONE OUTPUT (42) and the AFL/PFL LEVEL DISPLAY (45). A yellow LED above the switch indicates AFL (post-fader) engagement. (47) L & R MASTER FADERS These controls determine the level of the signal sent to the LEFT and RIGHT outputs respectively. As with all faders, the optimum setting is at unity gain (0).

(53) COMPRESSOR I/O (INPUT/OUTPUT) These 1/4" stereo (TRS) jacks allow the internal compressors for each SUB group to be patched to an input channel or to an external device. The tip carries the input (return) signal to the compressor and the ring carries the output (send). (54) SUB OUT These 1/4" (TRS) unbalanced outputs provide signal from the SUB groups. (55) AUX 1 - 6 OUT (UNBALANCED) These 1/4" (TS) jacks provide signal from the AUX buses. (56) AUX 1 - 4 OUT (BALANCED) These XLR connectors
