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.

1. Low Impedance (Low Z) Mic Input jacks: The low noise, high headroom Low Z mic inputs are for use with balanced, low impedance microphones.

,,

2. Line Input jacks: These 1/4 Tip, Ring, Sleeve (TRS) jacks are designed to be connected to (-10 to +4dBu) balanced or unbalanced line level sources.

The Low Cut Filter is activated by engaging this button. 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.

In order to achieve the best signal to noise ratio and adequate 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 and +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 detented 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 detented 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: There are two types of AUX (Auxiliary) available on the R Series mixers. Pre-fader (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.

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 MUTEswitch, 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 soundingmix,, of the balance of signals from each input.
