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.

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
5
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.
These Tip, Ring, Sleeve (TRS) jacks are designed to

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
detented

Page 5
R Series Mixers R-1604FX & R-2004FX
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.

Stereo Input Channel:
R-1604FX & R-2004FX R Series Mixers
The stereo channels on the R-1604FX and the R-2004FX feature two ,
,,
line level inputs with Tip / Sleeve (TS) jacks for left and right input signals. These
1

/
unbalanced
inputs can accommodate both stereo and mono inputs. When using a mono source,
connect the cable t o the LEFT input only and the channel PAN control will operate
like the other mono channels on the mixer.
Each stereo channel features a three band EQ section. The HI,control is centered
at 12kHz, the MID,control is centered at 2.5kHz and the LOW,control is centered at
80Hz. With a stereo source signal, the AUX / EFX controls operate the same as the
mono channels except they sum,,the stereo signal and it becomes a mono signal
on the AUX / EFX busses (outputs). This has no affect on the stereo signal being
sent to the MAIN MIX / ALT 3-4 busses.

41. Channel Insert Jacks (R-2004FX only):
equipped with Channel Insert jacks. These jacks are wired pre-fader, post EQ and pre Aux Send. The Insert
jacks provide a method of routing a channel's signal through a external serial effects device (such as a gate
or a compressor or even several serial processing devices connected to each other) and return that
processed signal back to the mixer channel. These insert jacks can also be used as post EQ direct outputs
for recording or other external signal routing. Special cables are required to accomplish some of these
configurations. Refer to the CONNECTIONS portion of this manual for more details.
