Resumen del manual
Please read it carefully before setting up this Vocal Sound System for the first time. Copyright0 1977 CBS Musical Instruments a Division of CBS Inc. »100 watts RMS power into 4 ohms with 220 watts peak music power. • Four separate input channels. Two jacks for each channel. « High or Low Impedance Microphones. (See Page 2). «Each channel’s controls separated and numbered for easy identification. «Reverb switch on each channel. •Two portable speaker columns each containing 4 8-inch high fidelity speakers. Four separate sets of volume and tone controls allowing boost and cut of both treble and bass on each of the four channels. ®Reverb switch on each channel.

For best results, the popular “high” impedance microphones should be used. However, in the event that microphone cables in excess of 20 feet are necessary, the use of “low” impedance microphones with a plug-in impedance matching transformer is recommended in order to maintain the treble response. CONTROLS Volume Control/Reverb—Controls volume for individual channel output. Pull knob out to switch reverb,, “on,” for each channel. Treble Control—Provides additional high frequencies as required. Bass Control—Regulates desired amount of bass response. MASTER CONTROLS Reverb Control—Regulates amount of reverb for all channels simultaneously. Volume Control—Simultaneously controls the output of all channels of the amplifier. JEWELED PILOT LIGHT Indicates when amplifier is turned on.

DISCONNECT POWER SUPPLY BEFORE CHANGING FUSE. loo Watts RMS HUM BALANCE OUTPUT INPUT MADE IN U.S.À. SPEAKER COLUMN OUTPUT JACKS REVERB UNIT INPUT/OUTPUT JACKS HUM BALANCE CONTROL Gives player control of polarity. Position “A” and “B” ground to each side of the AC line respectively. The “Off” position disconnects all but the third line chassis ground. Try each position to find minimum hum condition. —Disconnect amplifier AC plug from outlet before changing fuse. Remove fuse by pressing in and unscrewing cap. Use fuse type specified on chassis back plate. Turns amplifier on and off. Allows tube filaments to remain heated during standby periods. Amplification is instantly available without warm-up time. No danger of unwanted sound when in quiet periods. Connect output of amplifier to each of 2 speaker sound columns. Foot switch jack, for on/off foot control of reverb. Connect to internally mounted reverbation unit. Once the ground switch has been positioned to provide minimum hum, the hum balance control can be used to further reduce hum. This control should not need adjustment unless tubes or other components have been changed. Each 8 ohm column is supplied with four 8" high efficiency speakers. Two jacks are installed on each column. It is suggested that the lower jack be used to connect the SOUND COLUMN to the amplifier. The upper jack is convenient for connecting an optional auxiliary horn tweeter, monitor speakers or any additional sound column. If the red pilot light doesn't light when the power switch is turned "on," verify that the AC cord is plugged into an operating outlet and that the fuse is installed and operable. If in doubt try a new fuse. If there is no sound: 1 Verify that the "STANDBY" switch is in the "ON" position. Check the volume control on the channels in use and the Master Volume Control. At the "1" setting, the volume is off. Inspect the microphone and speaker plugs for positioning in their respective jacks. If the microphone you are using has an on/off switch, be sure this switch is in the "on” position. Check for bad connections or broken lines or connectors between the major components of the P.A. system. Minimizing Feedback Acoustic feedback is the condition which occurs when the microphone picks up a sound from the speakers and the sound is reamplified over and over until it builds into a loud, ear-splitting roar. This condition can develop with any Public Address System. A room will have a maximum volume level and when the volume is increased above that level feedback will result. The following suggestions will increase the volume which can be used in any given area without feedback resulting. Use a hig...
