Both standard phone jacks and XLR connectors (balance) are provided for outputs. • This compact size mixer contains as many as 24 channel inputs, making it possible to deal with a number of sources in a small space. The input channels 1 and 2 can also be used for microphones. • The Bus In jacks allows you to stack the mixer easily. • Four sets of Effect Send and Return jacks are provided. AUX Send can select Pre or Post. Returns consist of three stereo jacks and one with panpot. • The Phones Mix In allows you to monitor through headphones the monitor mix signals or sequencer's click sound. Moreover, the mixer features a highly sensitive Fader, easy-to-read Level Meter and Peak/Signal Indicator, etc. Q] Block Diagram and Signal Flowing ............................ 3 1.

Using any other adaptor will cause trouble. • Do not use the same socket.used for any noise generating unit such as a motor or variable lighting system. • Before connecting the AC adaptor to the socket, turn the unit off. • After connecting the AC adaptor to the Power Connector on the unit, connect the power cable to a socket. • When disconnecting the power cable from the socket, do not pull the cord but hold the plug. • Handle the cables gently. • When the unit is not to be used for a long period of time, disconnect the AC adaptor from the socket. • When making or breaking connections, turn all the unit off. • For about a few seconds, muting circuits work, therefore no sound is output. • Turn on the power amplifier after turning on the mixer, and turn off the mixer after turning off the amplifier. These should be done with the Faders of the mixer set to 0. • Operating this device near a neon or fluorescent lamp may cause noise interference. If so, change the angle or the position of the device. • Avoid using this device in extreme heat, humidity or where it may be affected by dust or vibration. • Keep the AC adaptor away from the unit, or hum may be caused. • Use a mild detergent and soft cloth for cleaning. Do not use solvents such as thinner. • Do not place or drop a heavy object on the power cable or connection cord. • Do not touch the inside of the unit, as it may cause you an electric shock and the unit a breakdown. • Do not let any solid or liquid material in this unit. • Do not give strong shock to the unit. • If this unit does not operate properly, unplug the power cable immediately and contact your local Roland service. • The XLR connectors of this unit adopt the connection system of 1 st=ground, 2nd= cold and 3rd = hot. 2 H BLOCK DIAGRAM AND SIGNAL FLOWING PRE FADER SIG AUÄ bfcLtL. I — 1. Channel Section UNBAL “ I BAL -Q- MASTER OUT-L j=Q^f1 PHONES UNBAL I BAL MASTER OUT-R Input signals are sent to the Headamplifier where the sensitivity is adjusted. When signals are fed in, the Peak/Signal Indicator light green, and when the input signals are too high levels, it lights red. The signals level-adjusted at the Headamplifier are processed at the Channel Fader, then divided into L and R at the Panpot, then finally reach the Master Section. A part of signals goes to the AUX Volume without going to the Fader, and the other signals go to the Effect Volume after the Fader instead of going to the Panpot. 2. Master Section a. Return The signals fed into Returns 1, 2 and 3 are sent to the Buffer Amplifiers, then to the Master Outputs after level-adjusted at the Return Volumes. Return 4's input singals also go to the Buffer Amplifier, then to the Return Volume, divided into L and R at the Panpot, and finally go to the Master Outputs. b. Phones Mix In The signals sent into this jack are processed at the Buffer Amplifier, mixed with the Main Bus signals, go to the Headphone Amplifier, then to the headphone volume, then to the Headphone Output c. Master Output The signals sent from each Channel are mixed, then level-adjusted at the master fader, then sent to the Master Outputs. d. Effect Send The signals sent from the Effect Volumes of each Channel are mixed, then level-adjusted at the Effect Send Volume, then sent to the Effect Sends. e.
