Powering On And Startup Procedures - Sonic Frontiers THE LINE SERIES Owner's Manual

POWERING ON & STARTUP PROCEDURES
Do not attempt to turn on your preamplifier until ALL prior steps
have been completed.
1. The Line 1 or Line 2 Power Switch (M), or Line 3 power but-
ton (AA) should be switched to the ON position. The LED display
window will initially remain blank for 10 seconds. During this
time (PRE-STANDBY), power is being applied to the tube fila-
ments. After 10 seconds six (6) dots will light up in the LED dis-
play window. The preamp is now in STANDBY mode.
Note: The Line 2 and Line 3 Power Supply LED (Z) will light the moment the power
switch is turned on.
2. You may now push the STANDBY button (L), and the output
MUTE will also be displayed in the LED window. The unit will
remain muted for a further 22 seconds, while the preamp stabi-
lizes, before going into OPERATE mode.
3. After 22 seconds, the preamp will be in OPERATE mode,
with the default BAL 1 input indicated and the left and right
numeric LED's will display your preset volume levels. All displays
are at maximum brightness, and the volume/balance will be set
to your saved levels. If you are turning the preamp on for the first
time, the volume will be set to 30.0.
4. When you have selected your desired input (BAL 1, BAL 2, or
SE1-SE4) you can change the phase polarity from 0˚ to 180˚,
change the mode from STEREO to MONO, MUTE the output,
and select TAPE concurrently. The maximum number of functions
displayed in the LED window at any time is five, plus the volume
levels.
5. When you select SSP (Surround Sound Processor) mode it will
illuminate in the LED display window, and all other functions in
the LED window will blank and are completely disabled. The
Surround Sound Processor signal is directly connected to all the
preamps balanced and single-ended (unbalanced) outputs.
When SSP is deselected the preamp will return to the previously
selected input and level (not the default settings).
SHUTTING OFF POWER
W A R N I N G
Always turn "off" your power amp first, before
turning off the preamp. Failure to do so may
cause a transient pulse to be delivered through
the amplifier to the speakers.
When shutting off power from the preamplifier, it must always be
put into STANDBY mode first. Then turn the power off via the
Power Switch (M) on the Line 1 & Line 2, or the Power Button
(AA) on the Line 3.
It is recommended that you leave the preamplifier in STANDBY
mode when unattended, rather than shutting off the main power
completely. This is done by simply pressing the STANDBY button.
However, if the preamplifier will not be used for an extended
period of time, you should shut off the main power completely.
