5. NOMENCLATURE AND FUNCTIONS
[Front]
1. Power switch
Power is switched on and off with each depression
of this switch.
2. Power indicator
Lights when the power switch is set to ON.
3. Assignment keys [ST, 1, 2]
Select one of the following output destinations
to which the post-fader input signals are routed.
Signals are output when pressed.
ST: Stereo output
1: MONO 1 output
2: MONO 2 output
4. Protective cover
Used to protect the setting position of the
assignment keys (3) from accidental operation.
It can be used as a writing plate.
5. Peak indicator
Lights when the output signal reaches 3 dB below
clipping. Be sure to adjust each input level so that
the Peak indicator does not light continuously.
6. Equalizer controls [EQ: LOw & hIGh]
Adjust stereo output signal tone.
LOW: Low frequency adjustment (20 Hz, ±15
dB shelving)
HIGH: High frequency adjustment (20 kHz,
±15 dB shelving)
7. Stereo output level control
Adjusts stereo output level.
8. Input level controls [1 – 6]
(1 – 2: Monaural input, 3 – 6: Stereo input)
Adjust the input level of each channel.
9. Mute key
Activates muting when pressed. (Indicator lights.)
[Muting function]
This function works only for the stereo output
channels. Attenuates the signals applied to
Channels 3 through 6 by detecting signals applied
to Channel 1 or 2. (This function does not work for
the monaural output signal.)
10. Monaural output level controls
Adjust monaural output level.
4. FEATURES
• 2 monaural inputs, 4 stereo inputs, 1 stereo output, and 2 monaural outputs. Assignable each input signal to
3 output channels individually.
• Sub-input terminals for stereo output channel and each of 2 monaural output channels.
• Microphone input or line input for monaural input selectable depending on the signal level. Built-in limiter
circuitry eliminates distortion under excessive input levels. High-pass filter as well as PAD (only for MIC input)
in the monaural line available by the internal switch settings.
• Peak indicator to detect clipping.
• An "Automatic Muting" circuit automatically mutes the stereo output signal by detecting the monaural input
signal. (ON/OFF switchable)
• A recording output and equalizer (high and low frequencies) for the stereo output channel.
• 2 channel monaural outputs usable as sum outputs for the stereo output channel individually by the internal
switch setting.
• Protective cover for protecting the setting position of each input usable as a writing plate.
• Knobs supplied in different colors and size easily replaceable depending on the intended use, improving
operability of the unit.
