manual abstract
Over' load indicators for each input. • PHONO IN jacks for direct connection of player. AUX IN jacks for connecting a tape recorder or submixer. • MASTER OUT and BUSS IN jacks for stacking. • REC OUT jacks for recording. • Peak indicating bar LED display. • Built-in reverberation unit. • Headphone monitor circuit. OWNER’S MANUAL THE CONTROLS AND THEIR FUNCTIONS CONTROL PANEL REAR PANEL CONTROL PANEL O STANDBY Switch Controls the ON OFF function of each channel, and determines the effect for the channel. At ECHO or REVERB, the channel is ON. ©OVERLOAD Indicator ©ATTENUATOR Control Each input channel is equipped with a preamp circuit with a normal input level of — 50dBm (microphone level). The ATTENUATOR control ©allows connection of high level inputs. When the OVERLOAD indicator © lights, the input ievel is too high and distortion may result. Turning the Channel 1 or 2 ATTENUATOR controls ©fully counterclockwise activates the record player equalization circuits. ©EQUALIZER: HIGH Control ©EQUALIZER: LOW Control Tone controls for the input channels. REAR PANEL a INPUT Jacks For inputs of-50dBm to -lOdBm. b MASTER OUTPUT Jacks For stacking mixers or for feeding an external amplifier. The output level is controlled by the MASTER VOLUME controls©©. c SPEAKER Jacks Two speakers can be connected to each output channel as long as the total impedance for each channel is over 40. d ECHO SEND Jack ©EFFECT Volume Determines the send level to the effect device selected with the STAND BY switch O. This output is taken after the VOLUME control©which means that the send level is affected by changes in the VOLUME control ©. ©PANPOT Control Determines the position of the sound in the stereo field. ©Channel VOLUME Control Determines the input level for each channel. ©MASTER VOLUME Control (left) ©MASTER VOLUME Control (right) Controls the overall output level at the speakers and at the MASTER OUTPUT jacks b. e ECHO RETURN Jack ECHO SEND —j INPUT OUTPUT}-RETURN f MIXING BUSS IN Jacks Direct line ievel connections to the mixing portion of the system. A second mixer can be connected here to increase the total number of channels avialeable for mixing. g AUX INPUT Jacks A line level buss input whose input level is controlled by the AUXILIARY VOLUME Control ©. When the pin jacks and phone jacks are used simultaneously, the phone jacks have priority. © HEADPHONE Jack © HEADPHONE VOLUME Control © REVERB VOLUME Control © ECHO VOLUME Control © AUXILIARY VOLUME Control These controls control the input level from the internal reverberation unit, external echo machine, and auxiliary device. © PEAK LEVEL Indicators Shows the output level of the PA-80. © POWER Switch © PILOT Lamp h RECORDING OUT Jacks For connection to tape recorder LINE IN jacks. The output level at these jacks is not affected by the MASTER VOLUME controls©©. I PHONO Jacks J GROUND Terminal For record player grounding. Also for making common ground connections to other equipment when needed to prevent hum. K AC OUTLET Maximum output: 300 watts; not affected by POWER switch ©. CONNECTIONS Make sure POWER switch © is OFF before making and breaking connections. Lower the MASTER VOLUME controls 0© to minimum before turning the POWER SWITCH © ON or OFF. Speaker system such as PS-60 or PS-80 (With speakers of 80 or more, two per channel may be used) Echo Machine (DC or RE series) Sub Mixer such as PA-80, PA-150, or Boss KM series (When using PA-80 or PA-150, use MASTER OUTPUT jacks) OPERATION Mixing with a microphone or instruments 1 8 After making the necessary connections, turn all the knobs to either 0 or OdB. Set the STAND BY switch to STAND BY. Turn on the power switch. Set the STAND BY switch of the channel to be used to either ECHO or REV. With the connected instrument in performance, after the Overload Indicator has lighted up, turn the ATTENUATOR control to the left until the overload indicator goes off. Then from that level, further turn to the left to set at approximately — I OdB. Set the channel volume to “5”. - . + □ □ 11 □ 12 □ For reverberation, adjust the reverberation volume and the effect volume of the channel where you want to give the reverberation effect to an appropriate level while emitting sound. FOR PLAYING RECORDS 16 □ Set the first and second channels to either ECHO or REV and set the channel volume to “0”. Turn the attenuator of the first and second channel to PHONO. Adjust the channel volumes and master volumes of the first and second channels to appropriate levels. Set the master volume for the “L” “R” channels to an appropriate level. For this, if the level meter lights up till OdB, the output is rating (125 W/4Q). While emitting a sound, adjust the tone quality (HIGH, LOW) you want to obtain with each channel. For stereo, set the panpot of channel 1 to “L” and for channel 2, “R”. For monaural, set both the channel one and two panpots to “0”. If the earth line of ...
