The labs are equipped with a TOA Power Amplifier, model A506A.
The amplifier is connected to a set of satellite speakers strategically
placed throughout the room for the best possible acoustics. Audio
can be played on the lab speakers from the instructor's computer,
the VCR, and the Cassette Player. To play audio in the lab from
the various devices, please refer to the diagram below.
Input #1 Currently NOT IN USE
Input #2 Currently NOT IN USE
Input #3 Volume for Wireless Microphone
Input #4 Volume for VCR (use only when showing movies in combination

Input #5 Volume for the Instructor Workstation. Volume is
also controlled by the Windows Volume Control. Always check
MASTER Volume Control
ON/OFF Switch. If there is no sound, make sure the
power is ON!
To disable audio in the lab, Either lower the Master volume
to 0 on the Amplifier, or Power it off.
Audio from the Instructor Workstation is shared between the
headphones (located on the Instructor Desk) AND the main lab
speakers. This allows an instructor to listen to audio at the
instructor's computer without disturbing the rest of the lab.
The Wireless Microphone works in combination with the amplifier.
Simply locate the on/off switch on the rectangular pack, switch
it to the ON position, and adjust the volume using input #3
on the amp. If the volume is set too high, feedback will result.
The default volume should be set to the correct level. Use the
lapel clip to position the microphone on a shirt pocket or collar.
