Notes:

•If your microphone’s cord is longer than 20 feet (6.01 meters), we recommend that you connect it to a balanced jack to reduce signal hum.

•If you connect a microphone to both jacks for MIC 1, MIC 2, MIC 3, or MIC 4, the microphone you connect to the unbalanced jack has priority.

•If you connect a microphone to either MIC 4 jack, set PHONO/MIC 4 on the back of the amplifier to MIC 4.

Connecting a Turntable

Turntable

PHONE/MIC 4

You can connect a low-level audio input source (such as a magnetic cartridge turntable) to the L PHONO and R PHONO jacks on the back of the amplifier.

If you connect a low-level audio input source to the PHONO jacks, set PHONO/MIC 4 on the back of the amplifier to PHONO.

To avoid a low-frequency hum, connect your turntable’s ground wire (usually black or green) to the amplifier’s GND terminal.
