FRONT PANEL FUNCTIONS

[1] MIC INPUTS

RCF F 6X provides 2 mono Mic inputs via XLR connectors. The Balanced XLR Microphone preamp input provides a gain range from 0 dB to -50 dB. All the F 6X’s MIC-LINE inputs are supplied with an 80 Hz Hi-pass filter. Enable the 80 Hz Hi-Pass filter when using voice microphone to reduce low frequency pop, bump and rumble noise (see section [7] of this manual). +48 V Phantom Power is provided for the Mic input: 1-2. Enable the Phantom power in the presence of Condenser and Electret Microphones or in the event of D.I. box usage (see section [9] ).

[2] LINE INPUTS

Line inputs TRS jack 1 and 2 provide a gain of +20 dB to -30 dB to line level signals.

**[3] STEREO INPUTS

**
RCA and TRS jacks 3/4 and 5/6 provide stereo inputs for line sources.
Note that MONO sources can be connected to jack inputs 3 and 5.

[4] MAIN OUTPUTS

These XLR male connectors provide +4 dB balanced audio output coming from MAIN MIX. Connect your main speaker system to XLRs, named L and R. The audio level of MAIN MIX OUT L and R is controlled by the dedicated MAIN MIX rotary knob (see section [24] of this manual). L and R XLR MAIN MIX outputs are replicated with L and R TRS jack.

[5] AUX/FX OUTPUT

This TRS jack connector provides +4 dB balanced audio output from the auxiliary send. Connect your stage monitors or external effects input here.

[6] FOOTSWITCH

This TS jack connector allows the use of MOMENTARY switches or foot pedals to MUTE and UN-MUTE the audio from the internal FX return. When the FX is muted via footswitch the red LED near the FX MUTE button lights up (see the section [23] of this manual). In this state, the effect can be unmuted either by pressing the FX MUTE button or the FOOTSWITCH again.

[7] CHANNEL 1 AND 2 GAIN

MIC input (XLR). This control permits the gain for MIC input to be set with a range from 0 dB to -50 dB.
If the LINE INPUT (TRS jack) are in in use the gain range permitted is from +20 dB to -30 dB.

[8] CHANNEL 3/4 AND 5/6 GAIN

STEREO LINE INPUT (TRS jack). The control allows a gain range from +20 dB to -30 dB.

[9] +48 V SWITCH

Dedicated to the Mic input this switch allows the enabling of the +48 V Phantom Power to the Mic input 1-2. Enabling the Phantom power is necessary in the presence of Condenser and Electret Microphones or in case of D.I. box usage.

[10] LEVEL METER

This 9-LED element level meter allows you to control the Main Mix output level. Keep the output level below the “CLIP” indication to avoid overloaded signals which can cause distortion.

[11] MONO CHANNELS EQ

[15] AUX/FX MASTER KNOB

This potentiometer controls the MASTER level of the single AUX SEND.

[16] PHONES LEVEL

This knob controls the level of the PHONES OUTPUT (section [20] of this manual). The Phones Output reproduces the Main Mix signal.

[17] PAN

These controls allow positioning of the signal present in the mono channel in the stereo image of the MAIN MIX.

[18] BAL

These controls, characteristic of stereo channels, allow balancing of the position of a stereo channel into the stereo image of the MAIN MIX.

[19] FX RET ROTARY KNOB

This potentiometer controls the level of the signal coming from the internal PRO DSP FX.

[20] PHONES OUTPUT

Connect headphones here to listen the MAIN MIX. To avoid hearing loss set the PHONES LEVEL control ( [16] ) to minimum (-∞) before connection and wear headphones.

[21] MONO CHANNELS ROTARY KNOB SECTION

This section allows the control of the single level of the 2 mono input channels.

[22] STEREO CHANNELS ROTARY KNOB SECTION

This section allows the control of the single level of the 2 stereo input channels.

[23] FX MUTE BUTTON
