PROFESSIONAL STEREO MIXER
2. STEREO INPUT SECTION
1. STEREO INPUT JACKS
These are unbalanced 1/4" phone jacks which input a stereo
source with a nominal input and impedance of +4dB/600
Ω
.
If a plug is inserted only in L/MONO, the same signal will be
sent to both the L and R buses.
The nominal input level for these jacks is -20dB ~ +14dB.
2. GAIN CONTROL (TRIM)
According to the level of the input signal, use this knob to
adjust the input to an appropriate level. The best balance of
S/N and dynamic range will be achieved if you adjust the
TRIM control so that the peak indicator lights occasionally.
This control adjusts the channel's input sensitivity between -
20dB and +14dB.
3. PEAK LED INDICATORS
This LED indicators let you check the level of the signal input
to the channel. The peak indicator lights when the input signal
reaches 3dB below the channels clipping point.
This indicator show the level of the post-EQ/pre-fader signal.
If the PEAK indicator lights more than briefly on high-level
transients, you should use the GAIN control to decrease the
input sensitivity of the channel. If this dose not work, reduce
the output level of the connected source.
4. 2 BAND EQUALIZER CONTROLS
This is a 3-band equalizer with center frequencies, range,
and type as shown below. The frequency response is flat
when the knob is in the "
ઓ "position.
5. AUX 1 CONTROL
This knobs control the level of the signals sent to AUX 1 bus.
This control is placed before the channel fader, it will be not
affected by the channel fader.
