If a tape or other line level recording or processing device
is being implemented, connect the left and right audio output
of the unit to the corresponding left and right Tape/
EPL Input of the Pre 2L. Also connect the left and right
Tape/EPL Outputs on the Pre 2L to the corresponding left
and right audio inputs of the external device.
Connect Set 1 of the Main Outputs (Q) on the Pre 2L to a
stereo amplifier or two mono amplifiers; left channel to left
channel and right channel to right channel. Set 2 of the
Main Outputs may be used under different situations and
in combination with Set 1. These situations include biamping,
the use of active crossovers, powered subwoofers and
other equipment; all situations being unique and system
dependent. Refer to the instruction manuals provided with
the other equipment before using the second set of
Outputs.
The Pre 2L is now ready for operation. Power the Pre 2L
by placing the On-Off button (K) in the ON position. The
Power Indicator LED (H) will stay DIM for approximately 45
seconds. During this time, the Main Outputs are muted
while the tubes are warming up and stabilizing. As soon as
the Power Indicator LED is at steady, normal intensity, the
Pre 2L is ready for operation.
Select a ready signal source with the Selector Switch (A).
Balance is adjusted through use of the Balance Control (B);
turning it left and right will adjust the left and right levels
r e s p e c t i v e l y. The center detent is an indicator for equal, or
balanced, left and right levels.
Volume is adjusted through use of the Volume Control (C).
Turning this control clockwise increases the volume level
of both channels. Be sure the level is sufficiently low when
turning the unit ON or returning to the OPERATE mode
after MUTING, to prevent damage to speakers, amplifiers
or the Pre 2L itself.
To record from a source, place the Tape/EPL-Source button
(F) in the SOURCE position, select the source material you
wish to record via the Selector Switch (A), and commence
recording. To play back a tape recording, place the Tape
EPL/ Source button in the TAPE position.
P D E T ACHABLE IEC AC POWER CORD SOCKET
Plug the Detachable Power Cord into this socket (see
Figure 4). The Pre 2L is factory set for the correct
operating voltage for the area in which it is sold (see
shipping box for voltage setting). If a different operating
voltage is required, please contact an authorized Sonic
Frontiers or Anthem dealer, distributor or the factory
directly.
Q MAIN OUTPUTS ONE AND TWO
These outputs connect to the single-ended inputs of
other units such as power amplifiers or a crossover
unit; connect left channel to left channel and right
channel to right channel. The set of two allows for
easier biamping and greater flexibility when dealing
with components such as electronic crossovers, a
powered subwoofer, etc.
