Rear Panel Features

19. DSP PROCESSORS

Two 24-Bit processors provide a host of great sounding effects including Flange, Reverb, Echo, & Chorus.

The channel EFF 1 & EFF 2 send controls deliver the sig- nals to the dual processors. Note: Reduce these levels if the red PEAK LEDs are flashing on the processors.

Turn up the MAIN controls to add effects to the MAIN L/R

OUTPUTS.

The MONITOR 1-2levels control the amount of effects that go to the MONITOR outputs.

20. EFF 1&2 SND JACKS

The EFF 1&2 SND jacks can send signals to external proces- sors. These are the same signals sent to the internal EFFECT 1 and EFFECT 2 processors.

21. AMP CLIP LED’s

The amp CLIP LEDs indicate when the internal power amps are starting to distort (clip). Reduce the MAIN L/R, MONI- TOR 1 or MONITOR 2 master volumes to prevent distortion.

22. PROTECT LED

The mixer will “protect”, engaging relays to mute the speak- ers if: a) impedance is below 4Ω on any amplifier b) short- ed speaker cables, or c) ventilation problems. If this LED comes on, shut the mixer OFF and check for cable prob- lems, proper impedance and obstructed rear cooling vents. If you encounter an over-heat problem, leave the mixer ON allowing the fan to cool down the internal components. The mixer will auto-reset.

23. POWER LED

The Power LED indicates when the mixer is powered on.

25. EFFECTS FOOT SWITCH JACK

The optional FS22 will remotely shut off EFFECTS 1 or 2.

26.PHANTOM POWER SWITCH AND LED

The PHANTOM power switch turns on the microphone phantom power in the channel XLR jacks. This power is used for supplying a voltage to condenser microphones. The LED indicates the phantom power is turned on. The phantom power will not damage conventional dynamic microphones. Note: Make sure the phantom power is switched off before connecting or disconnecting micro- phones to the mixer. It is recommended to allow 5 seconds for the phantom power to discharge before making any microphone connections.

27. POWER CONNECTIONS

The rear panel contains the POWER SWITCH and AC power cable connection.

28. AMP PATCH INSERTS

The AMP PATCH INSERT jacks offer full flexibility for mixer to amp signal routing.

These jacks are T-R-S (Tip-Ring-Sleeve). Tip is the power amp input. Ring is the signal sent from the mixer. The built- in power amp limiters are post insert.

Patching a compressor or equalizer between the mixer and the amp can be done by using a stereo insert cable (like Carvin’s AP1). Connect the RING signal to the INPUT of the external device, and the TIP signal from the OUTPUT of the device.

Plugging in a standard 1/4” cable (mono) into the AMP PATCH INSERT jacks allows any external signal to be sent to the internal power amps.

***DO NOT USE A BALANCED SIGNAL CABLE***

29. SPEAKER CONNECTIONS

For the RX800 and RX1200, there are 4 groups of speaker

EFFECT PARAMETERS

Each of the four effects have variable parameters that are easily adjusted by the SELECT and the PARAMETER controls to get the desired effect. Each “SELECT” & “PARAMETER” is described below. Note: An audible noise will be heard while adjusting the effects.

A)ECHO: Use SELECT to change the amount of regeneration (number of repeats). The PARAMETER control adjusts the delay time between the original signal and the echo.

B)REVERB: SELECT the amount of presence (high frequen- cies) in the reverb. The PARAMETER control adjusts decay.

C)CHORUS: SELECT the amount of reverb with your chorus. The PARAMETER control adjusts the depth.

D)FLANGE: SELECT the amount of speed with your flange (phasing effect). The PARAMETER control adjusts depth.

24.ADJUSTING THE GRAPHIC EQUALIZER

When the EQ sliders are in their center position, they do not affect the audio signal. When EQ sliders are raised or low- ered from this position, they boost or cut respectively a nar- row frequency band. To reduce feedback in the low fre- quency range, try lowering one of the 80 or 160 Hz sliders. High frequency feedback is usually reduced by lowering one of the 2k or 6k Hz sliders.

To help prevent feedback, the main speakers should be placed in front and away from the microphones.

For tone enhancement you may want to raise the 80, 160 (for deeper bass) and the 6k, 12k sliders (for crisper highs) form- ing a “smile” curve as shown.

jacks. Each group has one Twist-Lok (Speakon™) and two 1/4” outputs (wired in parallel).

AMP 1 is for LEFT speakers.

AMP 2 is for RIGHT speakers.

AMP 3 is for MONITOR 1 speakers.

AMP 4 is for MONITOR 2 speakers.

NOTE: 4Ω MIN IMPEDANCE PER AMPLIFIER (Maximum one 4Ω or two 8Ω speakers per amp). MAKE ALL SPEAKER
