IMPORTANT SAFETY INSTRUCTIONS

To reduce risk of electric shock, never open the unit. There are no user serviceable parts; refer service to an authorized Rockville service center.
Do not expose this unit to any kind of moisture.
Please ensure that the unit is situated in a properly ventilated area.

Functions

Channel Reverb control: Controls the mount of reverb added to the input signals.
Channel Treble control: ±15dB
Channel Bass:±15dB
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
Line/High impedance ¼” 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.
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.
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.
MP3 Player: Play button: Quickly press during play to pause; press button again to resume play.
- Stop button: Quickly press during play to stop current track.
- Repeat button: Quickly press during play to repeat current song. Press again to repeat all songs. Press again to exit repeat mode.
- Next button: Quickly press to go to next track.
- Previous button: Quickly press to go to previous track.
Play LED indicates MP3 player is on.

IEC AC Power socket
User serviceable fuse
Speaker outputs: 1/4″TRS jacks accept 4-ohm or 8-ohm speakers.
WARNING: Do not operate below rated minimum impedance.
Effect Return: 2-conductor 1/4″Iine input connects the mixer to the output of an external effects device which is receiving an unamplified main mix signal from the LINE OUT jack.
Line Out: ¼”TRS line output is used to connect a powered subwoofer or to send the line signal to an external device.
Tape input: Used to connect line level sources such as DJ controllers, mixers, samplers, CD players, cassette decks, DAT machines, MP3 players, etc. Mono audio sources can be connected using an RCA “Y” cable connector.
RCA Record out: Sends signal to a recording device or any other line level device.

Setup

In this setup there is a powered sub-woofer connected to the ¼”Out jack and two 8-ohm speakers connected to the ¼”8-Ohm Speaker Outputs on the back of the unit.

In this setup there is a powered stage monitor connected to the ¼” Out jack and two 8-ohm speakers connected to the ¼” 8-Ohm Speaker Outputs on the back of the unit.
