Volume Control and Audio Outputs
To increase volume
rotate the post
clockwise.
The RCA outputs
provide a standard
-10dbu unbalanced
signal.
Please refer to the
Advanced Serial
Control section of this
manual for details.
The volume control is the gray colored post protruding from the rear of the unit next
to the RCA jacks. It controls volume for the RCA line level outputs, as well as for
the optional speaker or balanced outputs. It does not control the volume on the
optional S/PDIF digital audio output.
If using power speakers, you may need to adjust the volume control to about 90
degrees from Off for an optimum. You can then adjust the volume on the powered
speakers.
You can also control the volume via serial or UDP commands. When using the serial
or UDP commands to control volume, you might want to set the manual volume
control knob at maximum otherwise full output volume will not be obtainable.
Balanced Outputs (optional)
The balanced output
level is +4dBu. The
S/PDIF output is a
standard IEC-958
signal.
The AM-4 Digital Audio Machine can be ordered with a module which supplies
balanced line-level outputs and a S/PDIF digital audio output. The balanced outputs
are provided on combination ¼ inch XLR jacks, and the S/PDIF output is on an RCA
jack.
Amplifier Outputs (optional)
Be sure to pay attention
to the speaker polarity
while making
connections.
If equipped with the amplifier option, each amplifier output is capable of up to
20Watts of power into 8 ohms. The line level outputs work along with the speaker
level outputs.
IMPORTANT NOTE: Do not bridge the speaker outputs or damage will occur.
