SPEAKERS B AND C Binding posts: For use with a single power amp. These left-right bind- ing posts are provided for speaker pairs “B” and “C”. You may connect only passive speak- ers here. See fi gure B.
NOTE: If you’d like to use a pair of powered speakers with your SRM-80A, do not connect them to the “B” or “C” binding posts. Set the AMP/SPK-B/C switch to the AMP- B/C position. Now you may use “A”, “B”, or “C” amplifi er / speaker line outputs for powered speakers.
FROM AMP OUTPUT: These Left-Right bind- ing posts are provided to connect the Left and Right speaker cables from the output of your power amplifi er when the AMP/SPK- B/C switch is set to SPK-B/C. The SRM-80A routes these amplifi ed output signals to either Speaker pair “B” or “C”, depending on which Speaker select button you press on the front panel or the SRM-RU remote unit. Be careful to connect the output of your power amp to these binding posts only. The relay that does the switching is rated at 8A/240 volts. See fi gure B.
REMOTE: Accepts the cable for the optional SRM-RU remote control unit. You will need to use a 5 pin din type cable a midi cable will not work properly.
MONITOR LINE OUTPUTS TO SPEAKER “C” /POWER AMP IN: Use these Left and Right 1/4” phone jacks to connect a pair of powered speakers or passive speakers with a power amp when the AMP/SPK-B/C switch is in the AMP-B/C position. If the switch is set to SPK- B/C there will be no signal present. See fi gure B.
MONITOR LINE OUTPUTS TO SPEAKER “B” /POWER AMP IN: When the AMP/SPK-B/C switch is in the AMP-B/C position use these Left and Right 1/4” phone jacks to connect
a pair of powered speakers or a power amp
/passive speakers. See fi gure A. When the AMP/SPK-B/C switch is set to SPK-B/C both B and C output signals will be present at these jacks. The SRM-80A uses these jacks to send either B or C output signals to your power amp, and the power amp’s speaker output is returned to the SRM-80A via the FROM AMP OUTPUT binding posts mentioned above. From there, the SRM-80A sends the amplifi ed signal to the passive speakers connected to the SRM-80A’s “B” and “C” speaker binding posts. See fi gure B.
MONITOR LINE OUTPUTS TO SPEAKER “A” /POWER AMP IN: Use these Left and Right 1/4” phone jacks to connect a pair of powered speakers or a power amp / passive speakers.
INPUTS/OUTPUTS “B,” “C,” AND “D”: RCA jacks for the inputs and outputs of an unbal- anced device such as a cassette, CD player/ recorder or MiniDisk.
INPUTS/OUTPUTS “A”: Left-Right 1/4” TRS jacks for the inputs and outputs of a balanced, pro level device.
SOURCE INPUTS: These 1/4” TRS jacks are provided to connect your studio’s main mixer, soundcard or multi-track recorder output to the SRM-80A.
LEVEL SELECT SWITCH: Selects +4dBu or 0dBu = 0 indication.
