Delta n 0 digital pre-amplifier
Balance control
This is set so that in the normal (' 12 o'clock') position the left
and right signals are amplified equally. Adjusting the balance control anti
clockwise will then move the stereo image to the left; moving the
control clockwise moves the image to the right.
For optimum performance the balance control is inside the
feedback loop of the Delta 1 lO's line amplifier stage. As the control's
range is limited to approximately + 1 OdB, it is not possible to mute one
channel completely.
Volume control
This adjusts the listening levels of the left and right channels
together, through both loudspeakers and headphones. Note that neither
the volume or balance controls affect the level of signals sent to the
tape outputs.
The volume control is motorised for remote control (see p
10). The special clutch used allows it to be adjusted manually without
any risk of damaging the drive motor Flowever, take care not to force
the volume knob beyond its end stops (at approximately 7 o'clock for
minimum volume and 5 o'clock for maximum).
Headphones socket
The Delta 110 incorporates its own high quality headphone
amplifier which is suitable for both high and low impedance headphones
using a standard 'A inch (6.35mm) jack plug. It is not generally suitable
for use with electrostatic headphones.
Note that the Delta 110's two main stereo outputs are
automaticaliy muted when the headphone jack is pushed home.
