O P E R A T I O N
Before plugging in the Pre 1L, check to see that the unit is
configured for the correct AC line voltage for country of
use. The operating AC line voltage is indicated on the side
of the shipping box. If the Pre 1L is set incorrectly for the
country in which it is to be operated, contact the dealer or
distributor in your area. If the unit is configured properly,
continue with operation.
Connect the Detachable Power Cord to the Pre 1L chassis
rear (see Figure 4). Plug your Pre 1L into the AC power
source.
Note: Never unplug your Pre 1L during operation.
First shut off your Power Amplifier, mute the Pre 1L
by depressing the Mute/Operate button (H), and
remove AC power by pressing and releasing
Power Switch (I).
All remaining connections to external equipment are made
with single-ended (unbalanced) type audio interconnect.
Connect source units to the Inputs of the Pre 1L (M) or
Tape Input (N); left channel to left channel and right channel
to right channel.
If a tape or other line level recording or processing device
is being implemented, connect the left and right audio out-
put of the unit to the corresponding left and right Tape/
EPL Input (O) of the Pre 1L. Also connect the left and right
Tape/EPL Outputs (M) on the Pre 1L to the corresponding
left and right audio inputs of the external device.
Connect Set 1 of the Main Outputs (L) on the Pre 1L 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 (L) may be used under different situations
and in combination with Set 1. These situations include
biamping, the use of active crossovers, powered sub-
woofers and other equipment; all situations being unique
and system dependent. Refer to the instruction manuals
provided with the other equipment before using the sec-
ond set of Outputs.
The Pre 1L is now ready for operation. Power the Pre 1L by
placing the On-Off button (I) in the ON position. The Power
Indicator LED (F) will stay DIM for approximately 45 sec-
onds. 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
1L 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 1L itself.
To record from a source, place the Tape/EPL-Source but-
ton (E) in the SOURCE position, select the source material
you wish to record via the Selector Switch (A), and com-
mence recording. To play back a tape recording, place the
Tape EPL/ Source button in the TAPE position.
