R1604: Each mono input channel feature a three band EQ section. The Hi EQ control has an upper shelf
limit of 12kHz, the Mid EQ 2.5kHz and the Low EQ 80 Hz. Each control has a range of -15dB to +15dB cut
and boost.
* The EQ control section should be used in conjunction with the Low Cut Filter (3) to add extra
warmth or extra punch to the mix where necessary.
AUX Section:
There are two types of auxiliary: PRE FADER and POST FADER.
A PRE FADER auxiliary occurs in the signal path before the main channel fader, and therefore the amount of
signal going down the auxiliary is only affect by the auxiliary level control. Any change in the main fader level
will not affect the amount of signal going down the auxiliary. This type of auxiliary is often used for a monitor
mix when the levels need to be independent of the main mix.

Features of the R Series Mixer

Mono Input Channels:

1. Low Impedance (or Low Z) Mic Inputs
The low noise, high headroom Low Z mic inputs for use with balanced or
low impedance microphones or low level external equipment with XLR
connectors.
2. Line Inputs
The features of balanced/unbalanced high impedance mono line inputs for
use with high level signals with1/4 phone plug connectors.
3. Low Cut Filter
The low cut filter can be activated by pressing this button. The slope of this
filter is 18dB/oct., -3dB at 75Hz and should be used when it is necessary to
eliminate or reduce background rumble, breathing noises and popping.
4. Gain Control
The input level on the Mic channels is controlled by using the Gain Control
to achieve the best signal to noise ratio and dynamic range. The Gain
control should be used in conjunction with the Peak LED which will
illuminate if the input gain is too high. The gain circuit has a wide range
from -10dB to -60dB.
5. EQ Section:
R2004: Each mono input channel features a three band EQ section with
semi-parametric mid bands. All bands provide boosts or cut of up to 15dB.
In the center position, the equalizer is off (FLAT). The Hi EQ control has
an upper shelf limit of 12kHz and the Low EQ at 80Hz. For the Mid range,
the console features a semi-parametric equalizer with a filter quality (Q) of 1
octave, tunable from 100Hz to 8kHz. Use the Mid control to set the amount
of boost or cut, and the FREQUENCY control to determine the central
frequency.
