¥ MIC (Microphone Controls) ø CH-1 to CH-4 (Channel Input Controls)

1MIC 1 input jack

Use to connect a microphone with either XLR or PHONE

type jack.

2TREBLE control

Adjusts high-range frequencies on microphone 1 and 2. Center click position is provided for flat response. Rotate the knob clockwise to augment treble response (to +12dB), and rotate counterclockwise to diminish

treble response (to –12 dB).

3BASS control

Adjusts low-range frequencies on microphone 1 and 2. Center click position is provided for flat response. Rotate the knob clockwise to augment bass response (to +12dB), and rotate counterclockwise to diminish base

response (to –12 dB).

4MIC 1 LEVEL

Controls sound volume on microphone 1 (attenuation:

–∞to 0 dB)

5MIC 2 LEVEL

Controls sound volume on microphone 2 (attenuation:

–∞to 0 dB)

6MIC switch

Use to select microphone input. OFF: Disables microphone 1 and 2 ON: Enables microphone 1 and 2

TALK OVER: Enables microphone 1 and 2 while attenuating other sound levels. The amount of attenuation can be controlled by setting the rear-panel TALK OVER LEVEL, within the range –4 dB to –20 dB.

7Input selector switches

Use to select an input source from among the com- ponents connected to the various channels.

CH-1: Switches between LINE 1 and PHONO 1/LINE 2

CH-2: Switches between LINE 3 and PHONO 2/LINE 4

CH-3: Switches between LINE 5 and PHONO 3/LINE 6

CH-4: Switches between LINE 7 and MIC 3/PHONO 4

¶On CH-1 to CH-3, the rear panel PHONO/LINE switches are used to switch between PHONO 1, 2, 3 and LINE 2, 4, and 6.

¶On CH-4, switching between MIC 3 and PHONO 4 is

based on the presence/absence of a plug in the MIC 3 connector (when a plug is inserted, MIC 3 is selected).

8TRIM control

Use to control the input signal level.

Rotate clockwise to increase the level (to +9 dB); rotate counterclockwise to decrease the level (to –∞)

9HI control (high-range equalizer)

Use to adjust high-range frequency of input.

When the dial is set to the center click setting, flat response is provided.

Rotate clockwise to increase response (to +12 dB), and rotate counterclockwise to decrease response (to –26

dB).

0MID control (mid-range equalizer)

Use to adjust mid-range frequency of input.

When the dial is set to the center click setting, flat response is provided.

Rotate clockwise to increase response (to +12 dB), and rotate counterclockwise to decrease response (to –26 dB).
