Functions

1. Channel Reverb control: Controls the mount of reverb added to the input signals.

2. Channel Treble control: ±15dB

3. Channel Bass: ±15dB

4. Microphone/Low impedance XLR input: Connect balanced low-impedance microphones with an input impedance of 1K ohms. PIN 1 = shield, PIN 2 = positive (hot), PIN 3 = negative (cold)
   WARNING: When using condenser microphones, make sure that Phantom power (15V) is switched on (see item 15).

5. Line/High impedance 1/4″ input: This input may be used as either a high-impedance microphone input or for line-level devices such as a cassette player, CD player, video projector, or laptop. Will also allow connection from an electric guitar, bass, or keyboard. It is a two-conductor input with an impedance of 10K ohms.

6. Channel volume control: Volume level should be lower than the master level. This control acts as a preamp; if you are using a device that has a volume output control you will need to match levels by adjusting the level controls on each unit.

7. Master EFFX controls:
   Volume: Controls the level of the effects added back to the master mix.
   Echo: Controls character of the reverb that is added back to the master mix. It changes the rate at which the echo decays.
   Delay: Controls the delay of the reverb that is added back to the master mix. Increasing this control will simulate the effects of a larger room.

8. MP3 Player:
   Play button: Press during play to pause; press button again to resume play.
   Stop button: Press during play to stop current track.
   Repeat button: Press during play to repeat current song. Press again to repeat all songs. Press again to exit repeat mode.
