Operating instructions
The 740A has a custom-made display on the front of the unit showing
the current status and allowing you to access the 740A System
Configure menus. Here you can adjust the listening settings of the
amplifier to personal preference. The menu system is easy to navigate
and control, simply by using the input select buttons to turn a feature on
(solid circle) or off (no circle) and the volume control knob to
increase/decrease settings.
Volume
Adjust the volume control knob on the front panel (or using the remote
control). The display will show the change in volume in decibels (dB).
‘OdB’ indicates maximum volume while lower volume settings progress
into the negative range. This can also be changed to volume units (0-72)
in the System Configure menu.
Speaker A/B
Press the
Speaker A/B
button to scroll through the speaker sets
connected via the rear panel: speakers A, B or A and B.
Balance
Press the
Mode
button to enter Balance mode. BALANCE will appear on
the display and can be adjusted using the volume control. Press the
Mode
button again to return to Volume mode or wait 5 seconds for the
740A to automatically exit Balance mode.
Bass and Treble
These controls allow subtle adjustments to the tonal balance of the
sound. Press to release and rotate to adjust (press back in when desired
settings found). An icon appears on the display to show if Bass/Treble
has been adjusted. In the central position these controls have no effect.
These controls only modify the sound through your loudspeakers and
the Pre-Out sockets; they do not affect the signals sent through the Tape
Out connections. With a well produced CD and a good system the tone
controls are unnecessary and can be switched out by pressing the
Direct
button:
This completely removes them from the signal path for maximum
fidelity. If the musical recording is of poor quality or other factors are
affecting the sound quality, it may be necessary to adjust the tone
controls to compensate.
