Power
When power is applied, the STANDBY key b is used for power control. The
Standby light c shows green when the Pre aCA7.5 is operating and glows
red when in standby mode. The Pre aCA7.5 will switch from standby to on,
when any input key h-1# is selected.
In regular use the Pre aCA7.5 should be connected permanently to the mains
power supply. When left unattended for a long period (vacations etc) it should
be disconnected from the AC supply.
When the Pre aCA7.5 is switched to Standby, all settings for input selection
and Volume/Balance are retained.
Selecting an Input
The INPUT SELECT keys h-1# switch selected input sources. When an input
key is selected, the red indicator above the key will turn on.
Tape/Disc Playback and Recording
Playback: You can play back a recording by selecting the appropriate key
TP1 h (for a tape recorder connected to TP1) or TP2 g (for a tape recorder
connected to TP2). When TP2 is selected the indicator above the selected
key will light in addition to the selected source. To cancel TP2, press the TP2
key again. If the tape recorder has a three-head facility, selecting the TP2 key
will monitor the recording directly from the third head, whilst recording.
Recording: To record, select an input to record with the relevant Key i-1#
and follow the recording instructions in your tape deck manual.
Copying: Tape copies may be made when playing a tape from the TP1 input
to a tape recorder connected to the TP2 circuit of the Pre aCA7.5.
Note: You cannot record from Tape 2 to Tape 1.
Volume and Balance
(Refer to fig 4)
The LEVEL CONTROL f of the Pre aCA7.5 performs the dual functions of
volume and balance.
Volume: In normal mode the LEVEL CONTROL controls the volume in 1dB
steps. The light ring around the knob is calibrated to show the current
loudness level. When the volume is at minimum the first indicator on the light
ring will be RED. As the volume increases a GREEN light moves clockwise
around the ring. The volume setting is stored when the unit is set to standby.
Balance: Press the BALANCE control key on the remote control f to
change the mode of the front panel LEVEL CONTROL f to that of Left/Right
Balance. The light ring works in "reverse video" with the unlit section
indicating the position of L-R balance. You can alter L-R balance by up to +/-
4dB or switch one channel off when the control is turned to an extreme.
Mute
Pressing the MUTE Key a will fade the volume to minimum level without
disturbing the existing setting. When muted the RED minimum level indicator
will light as well as the existing GREEN light to show that the output is muted.
Move the volume knob up or press the Mute key to fade back up to the
original volume setting.
Listening to headphones
To listen to headphones, press the PHONES key d. The MUTE light at the
bottom of the light ring will now glow orange. The speakers will now be muted
for headphone listening. Press the PHONES key d again to restore
loudspeaker operation.
NOTE: The HEADPHONES key d only operates when headphones are
connected to the rear panel socket of the Pre aCA7.5.
Caution: If you have been listening to headphones at high volume, be sure to
turn the level down before you switch to normal loudspeaker operation.

Programmable Input Sensitivity
You may find an audible difference in level when switching from one input to
another due to the differing outputs of your source components. The unique
calibration memory of the Pre aCA7.5 can be programmed to match the
sensitivity of all inputs with reference to the CD input. To program an offset:
1.
Select CD input and set the volume control to a comfortable listening
level.
2.
Select the desired input and hold the input key down. The volume
display switches to show input offset.
3.
Adjust the level to the same audible volume as the CD player. The
display will read the offset applied.
4.
Press the input key again to store this setting.
Repeat Steps 2 - 4 for each input to set the appropriate sensitivity level.
Fig. 5(a) - 5(c) shows settings for Input Sensitivity levels set -2 dB, 0dB and
+2dB relative to the CD input respectively.
