Getting Started

1. Power Supply

The R Series mixer is supplied with an external power supply unit. Use only the power supply supplied with

your mixer. Using any another power supply could damage your mixer or other equipment. Connect the

power supply to the mixer BEFORE connecting it to the power source outlet. It is important to allow for

adequate ventilation for the mixer as it may become warm during long periods of operation. Be sure to allow

for free air flow around the mixer. The mixer is shipped with the correct power supply for the country in which

it is to be used. This can be verified by checking the label on the power supply. If the mixer is to be used in a

country using a different source supply voltage, then a different power supply will be required. Consult your

dealer to acquire the correct power supply for the appropriate location.

2. Packing

The exterior and interior packaging has been designed to protect the mixer during transit. If any shipping

damage has occurred, consult your dealer and the shipping provider.

3. Safety

Avoid excessive heat, humidity, dust and vibration. Store and operate the mixer away from locations where it

is likely to be exposed to high temperature or humidity. Also, avoid locations which may be subject to

excessive dust and lint or vibration / physical shocks that could cause mechanical damage to the mixer.

WARNING: REFER ALL MAINTENANCE, REPAIRS AND MODIFICATIONS TO QUALIFIED SERVICE

PERSONNEL! THIS PRODUCT CONTAINS NO USER-SERVICEABLE PARTS!

For the protection of the mixer and other audio equipment, always turn off the power on the mixer and other

system components before connecting or disconnecting audio cables.

4. WARRANTY

The R Series mixers come with a limited warranty covering any defects in workmanship for a period of one

year from the date of purchase. This warranty is non-transferable and applies only to the original purchaser.

If any warranty related issues occur, contact your dealer.

Mono Mic / Line Input Channels:

microphones.

2. Line Input jacks:

be connected to (-10 to +4dBu) balanced or unbalanced line level sources.

3. Low Cut Filter:

When activated, this filter provides an 18dB per octave roll off with -3dB at 75Hz

and can be used to reduce mic handling noise, wind and popping when

microphones are used. It is also useful for minimizing excessive low frequency line

level signals.

4. Gain Control:

dynamic range, the input preamp level of each Mic channel is controlled by the

Gain Control on each channel. To set the Gain Control, place the desired channel

in SOLO mode and watch the left LED bar-graph meter in the Master section of the

mixer while the signal source for that channel is active (whether it be a singer using

a microphone or an instrument connected to the LINE INPUT of the channel). The

ideal level is between 0dB an d +3dB. If the PEAK LED on the channel lights up

consistently, the Gain Control is set too high. It is acceptable for the PEAK LED to

flash periodically, especially with instruments like drums or level peaks during loud

portions of a performance.

5. EQ Section

Each mono channel on the R-1604FX features a three band

Equalization ( EQ,,) section. Each band allows for up to 15 decibels of boost

(increase) or cut (decrease) of the signal in the tone range for which it controls (HI,

MID, LOW). In the center position, the equalizer is bypassed (FLAT) and

the control has no effect on the tonal characteristics of the signal. The EQ

control is centered at 12kHz and the EQ control is centered at 80Hz.

Each mono channel on the R-2004FX features a three band Equalization section along

with a sweepable mid-band control. Each band allows for up to 15 decibels of boost (increase) or cut

(decrease) of the signal in the tone range for which it controls (HI, MID, LOW). In the center

position of the knob, for each band, the equalizer is bypassed (FLAT) and the control has no effect on the

tonal characteristics of the signal. The EQ control is centered at 12kHz and the EQ control is

centered at 80Hz. The band control is slightly different in that it has two knobs. One knob controls the

center frequency (100Hz to 8kHz) and the other knob controls the amount of boost or cut for the selected

frequency.

AUX SECTION:

(labeled PRE) and post-fader (labeled POST).

: A PRE fader aux derives its signal independent from the channel fader. Any changes made on the

channel fader do not affect the signal that is sent to the AUX buss (output). This type of AUX is

commonly used for a stage monitor mix in sound reinforcement applications. It could also be used as a

headphone mix in a recording application.

There are two types of AUX ( Auxiliary ) available on the R Series mixers. Pre-fader

POST: A POST fader aux derives its signal after the channel fader. Any changes

made on the channel fader affect the signal level that is sent to the AUX

buss (output). This type of is commonly used to supply audio signals to an

effects processor such as a reverb or a delay in both sound reinforcement and

recording applications.

Each AUX control is mono and post EQ. Any changes

made to the equalizer section of a channel will affect the AUX / EFX signals as well

as the MAIN output signals. There is 15 dB of gain available for each AUX / EFX

SEND knob.

With this switch, it is possible to change AUX 1 to either

PRE or POST fader mode.

Each EFX control is post-fader. Any changes made to the

channel fader will also result in a change of level of the signal being sent to the EFX

buss (output).

On the mono channels, the PAN control adjusts the balance of

the signal being sent to the left and right MAIN MIX (or ALT 3-4, if a channel is

muted). Turning the PAN control fully left on a stereo channel will cause the right

input,s signal level to decrease. Turning the PAN control fully right on a stereo

channel will cause the left input,s signal level to decrease.

Engaging a channel,s SOLO button allows for monitoring the input signal

of that channel (as well as any other channels that are in SOLO mode) through the

Headphone and Control Room outputs, as well as being able to see that signal level in

the left LED bar-graph meter. When any channel is in SOLO mode, the meter will only

display the levels of the channel(s) that have their SOLO button(s) engaged. The

SOLO ON LED lights up (located just below the LED bar-graph meters) when any

SOLO buttons are engaged.

The MUTE switch, on each channel, allows for muting of the channel,s signal from the

MAIN MIX buss and also reroutes the signal to the ALT 3-4 output when it is engaged. The AUX mode

and EFX send busses (outputs) are affected by an engaged MUTE button and the signal is removed from those

busses when a channel (or channels) are muted. The AUX buss is not affected by an engaged MUTE

button.

The PEAK LED lights up when the input signal is driven too high in level.

The SIG LED ( Signal Present ) will light up when a minimal signal level of -20dBu is

present at the input of a channel.

The fader allows for control of the level of the signal that is being sent to the

MAIN MIX fader, or the ALT 3-4 master fader, if the channel is muted. When the fader is set at the 0dB

position, the signal is not being increased or decreased from the level that has been set with the Gain

Control. Adjust the level of each fader to acquire the best sounding mix,,of the balance of signals from

each input.
