Controls and Functions

1. CHANNEL 1 Input

This unbalanced input lets you connect a low-impedance dynamic microphone (30-600 ohms). The connector uses 6.3 mm phone jack. The input features VOICE PRIORITY, which overrides all other input signals once a microphone message is sensed. If you want to have this function disabled permanently, please contact a Yorkville Sound Service Center.

2. MUTE Switch

This switch lets you turn VOICE PRIORITY on or off for INPUT 1 (1).

3. Input Level Controls

These controls let you individually set the volume of the sound source that is connect- ed to INPUT 1, INPUT 2, INPUT 3, INPUT 4, AUX 1 and AUX2 / TAPE. Turning the control clockwise increases the volume of the corresponding source. We recommend to leave the controls of the inputs not used to their minimal setting of “0.”

4. Music Signal Monitor Output Level Control

This control lets you set the volume of the sound output that is connected to the MONITOR OUTPUT (5) and 1W/8Ω (31). Turning the controls clockwise increases the volume of the corresponding source.

5. MONITOR Output

This allows the signal output of the AUX1, AUX2 / TAPE, CASSETTE and TUNER to be monitored. It can be used to control an audio appliance with input with impedance over 600ohms (e.g. earphone or an additional amplifier etc.). The output signal is controlled only by the volume controls of the AUX1, AUX2 / TAPE, TUNER and music signal level control

(4). This function also behaves as a toggle switch for the 1W/8Ω (31) additional loudspeaker.

6. POWER Switch

Using the POWER switch lets you turn the main power on or off.

7. Indicator

When switching the amplifier’s power on, the Peak/Limiter indicator lights momentari- ly. When the amplifier’s output overloads, the OVERLOAD indicator lights and inter- rupts the output. For best equipment life, adjust the volume to a lower setting.

8. LED VU-Meter

This LED indicator displays the signal’s output level. For proper operation of the am- plifier, a correct volume setting is of major importance. The first eight LED segments on the lower portion represent the area between -20dB and 0dB, in which the output- ted level should be kept. If the last two segments on the upper portion are lit for a long period of time, this means that the output signal is being driven into clipping (which usually results in audible distortion). You need to adjust the volume to a lower setting.

9. Zone Selection Switches

Speaker lines of each zone (Z1 ~ Z4) can be connected or disconnected indepen- dently. To connect the speaker lines, turn the switch on. To disconnect the speaker lines, turn the switch off.
