Manley PURIST PREAMPLIFIER - Manual (Page 6)

FRONT PANEL
A SET GAIN Switch to select general gain of the preamp to personal preferences. Due
to a lack of current standards of power amp and preamp sensitivity this feature
provides a simple method to scale the overall gain of the system or allow one to
reduce the power amp gain to reduce noise. Note that changing this switch can
introduce "pops" into the system - so MUTE the audio momentarily while changing
this control.
B SELECTOR SWITCH Switch to select between inputs. Counterclockwise:
VIDEO, TUNER, DIG ,CD, TAPE, AUX,. NOTE: always turn volume control
(level) down before switching selector switch to avoid surprise differences in source
levels. NOTE: inputs which have nothing plugged in to them can pick up noise.
C VOLUME CONTROL Adjust the stereo input level of the selected signal.
D&E BALANCE ADJUSTS These very useful controls modify the gain of each channel
by changing the line amplifier's feedback. When set to 12 o'clock (straight up) both
channels will produce the same gain at optimum setting. Rotating the controls
clockwise will increase the gain (lower feedback) and rotating the controls
counterclockwise will reduce the gain (more feedback) of the corresponding channels
with approximately 10 dB of total swing. Thus neither control will fully mute the
signal. Different sound characteristics can be achieved with these controls to optimise
the gain, speed, and slew rate of this preamplifier to your system, but small
differences of level between two channels can be equalled or trimmed out with these
controls when used as dual-mono balance controls. In some systems the optimum
setting of both controls is fully clockwise, thus, the least feedback. Musically this
tends to produce a subtly more aggressive, fast, punchy and more forward
presentation. In systems that already have this quality the optimum setting will likely
be from fully counterclockwise to a mid position. Some describe the more feedback
sound as more laid back, mellow or "tube-like" warmth. Experiment! There is no
right or wrong. Your taste will set these controls (maybe even differently for different
CD's!)
F MUTE / OPERATE Toggle switch that provides a simple cut or mute to the audio
signal.
G NAME PLATE Illuminated from the back when the unit is powered on.
F POWER SWITCH Switch up (1) to turn on the power, down (0) to turn the power
off. Do not ever flip the power on and off and on and off rapidly-- you can damage
the power supply.
