9. AC inlet
Connect the supplied power cord.
10. Remote control connector
Removable terminal block.
(1) Remote volume control terminals
[REMOTE VOLUME]
Connecting a 10 kΩ linear taper volume control
across these terminals will allow remote control
of preamplifier output and speaker output levels.
(2) Power remote control terminals
[POWER REMOTE]
Allows remote control of the unit's power
ON/OFF.
No-voltage make contact input.
(3) Mute control terminals [MUTE CONTROL]
Shorting these terminals mutes the Mute
Receive inputs (the inputs set to be muted).
The mute control works regardless of whether or
not there is a signal to a Mute Send input (the
input set to activate muting).
11. Mute sensitivity control [MUTE SENSE]
Adjusts the threshold level in a range of 36 dB
for the Mute Send inputs to activate the mute
function. Turn clockwise to increase the
threshold level (lower sensitivity), and
counterclockwise to decrease the level (higher
sensitivity).
12. Preamplifier output jack [PRE AMP OUT]
0 dB, 600 Ω, unbalanced RCA jack. Outputs all
input signals. Connects to a signal processor
such as a limiter or equalizer. (Refer to p. 7.)
13. Mute assignment switches
[MUTE ASSIGNMENT]
Assign the individual inputs to Mute Receive
(inputs to be muted) or Mute Send (inputs to
activate muting) function. When a signal enters a
Mute Send input, Mute Receive inputs are all
muted.
(1) Mute Receive assignment switches
[MUTE RECEIVE (INPUT CH)]
Allow all inputs (INPUT 1 – 8 and Module) to be
assigned to Mute Receive function.
(2) Mute Send assignment switches
[MUTE SEND (INPUT CH)]
Allow the inputs 1 – 3 and Module input to be
assigned to Mute Send function.
Notes
• Avoid assigning both functions to the same
input.
• The audio signal level to activate muting is
independent of input volume settings. So, the
Mute Receive input is muted if a signal enters
the Mute Send input even when the input
volume is turned down.
To avoid unwanted muting caused by
This figure represents the A-724.
3. Input 1 – 8 volume controls [INPUT 1 – 8]
Adjust the corresponding input signal levels. Turn
each control clockwise to increase and
counterclockwise to decrease the level.
4. Master volume control [MASTER]
Adjusts the overall signal level. Turn the control
clockwise to increase and counterclockwise to
decrease the level.
5. LED level meter
Indicates an output level.
6. Bass control [BASS]
Adjusts bass response. Turn clockwise to increase
bass output, and counterclockwise to decrease it.
The center position provides flat characteristics.
7. Treble control [TREBLE]
Adjusts treble response. Turn clockwise to
increase treble output, and counterclockwise to
decrease it. The center position provides flat
characteristics.
8. Module input volume control [MODULE]
Adjusts the signal level of the module input on the
rear panel. Turn the control clockwise to increase
and counterclockwise to decrease the level.
