Resumen del manual
Your SRM-80A will make monitoring, mixdown, and dubbing simpler and faster, thus helping you achieve professional results.

By connecting the control room outputs of your mixer, inputs and of up to three power am pli fiers or powered speak ers, speaker outputs of one stereo power amplifier, and up to three pairs of speakers, you will have a highly useful and sophisticated audio playback monitor system.

Please also refer to the “System Set-Up #1” drawing on the facing page. . Cables needed: 2 Pair: Speaker to Binding Posts, the banana plug type (Speakers B, C) 1 Pair: 1/4” TRS Balanced to Monitor Line output “A” (Powered Speakers) 6 Pair: RCA I/O to Devices 2 Pair: 1/4” TRS Balanced to Device “A” L/R I/O 1 Pair: 1/4” TRS Balanced to “SOURCE” L/R Input 1 Pair: 1/4” TRS Balanced to Power Amp L/R Inputs 1 Pair: Power Amp Out to “FROM POWER AMP OUT” Binding Posts (banana plugs) . Make sure SRM-80 and all other devices are switched “OFF” before making any cable connections. . Decide which devices will be labeled “A”, “B”, “C”, and “D”. Device “A” should be any pro level balanced units, such as a DAT machine. Label the Output Select Switch and the speaker pairs on the front panel tabs. Use adhesive labels so you can relabel for different configurations. . Mount the SRM-80 in your rack. Depending on your setup, it may be easier to cable all your gear before mount- ing the SRM-80 in your rack. Otherwise, go ahead and mount it now. . Set AMP/SPK - B/C Switch to SPK - B/C. . Connect passive speaker cables to “SPEAKER C” and “SPEAKER B” Binding Posts. . Connect Power Amp L/R Output cables to “FROM AMP OUTPUT” Binding Posts. . If you have the optional SRM-RU remote unit, which we highly recommend, connect its 5-Pin cable to “RE MOTE.” . Connect 1/4” TRS Balanced cables from your powered monitors to MONITOR LINE OUTPUT “A” L/R. . Connect 1/4” TRS Balanced cables from MONITOR LINE OUT PUT “B” L/R to your power amp “IN” L/R. . Connect RCA cables from “L/R In/Out” to devices “B”, “C”, and “D”, according to your setup plan. . Connect 1/4” TRS Balanced cables from “A” L/R, I/O to device “A” . Connect 1/4” TRS Balanced cables from “SOURCE” L/R to source device. (e.g. mixing console stereo out or soundcard out). . Set the Ground Lift Switch to the position that reduces any hum or buzz. . Set the “0db / +4db” switch to the appropriate meter scale for the equipment being used. . Power up your equipment, being sure to turn on your power amp last. . Set “SPEAKER TRIM” controls at about 75%. After powering up the system, adjust levels as needed. To dial in your speaker levels use broadband pink noise and sound level meter. The Alan Parsons/Stephen Court align- ment CD is very good, and a decent meter can be had for about $40 at Radio Shack. For using more than 1 pair of power speakers or multiple power amps see System Set-up #2 on the next page. SRM -80A / E – SIGNAL ROUTER/MONITOR source select knobs labeled OUT PUT SELECT A through OUTPUT SELECT D. Monitoring any of these sources can be done using the MONITOR SELECT knob, high- power headphone amp and uniquely thought- out speaker selection system that consists of three balanced line level speak er outputs A, B, and C. All of these outputs are compatible with powered monitors or passive speakers using a power amp. The unique feature is that the B and C outputs can be combined into one output for use with 2 pairs of passive speakers and only one power amp.

Each mon i tor speaker output has its own front panel trim control, so equal listening levels can be main tained despite differ enc es in speaker ef ficien cies. The SRM-80A has balanced inputs for the SOURCE and A inputs, and balanced outputs for channel A output and A, B, and C monitor line outputs. INPUTS B through D utilize un bal anced RCA jacks. The SRM-80A allows easy signal routing between these dissimilar jacks. TO SOURCE IN DAT RECORDER TO "B" NIFROM “B” OUT OUTPUT ...
