A SELECTO R SWITCH

This knob is rotated to select a Line Level Input (S).
The Selector Switch is bypassed when the Tape/EPL
(External Processor Loop) mode is selected by
depressing the Tape/EPL-Source button (F), or when
SSP mode is selected by depressing the SSP button (D).

B BALANCE CONTRO L

This knob controls the relative balance of the left and
right channels to compensate for any discrepancies
caused by speaker placement, source imbalance, etc.
Full rotation to the left or right of the center detent will
fully attenuate the left or right channel.

C VOLUME CONTROL

This knob allows variable control over the Pre 2L’s output
level. Turn it clockwise and the music gets louder!

D - SSP (SURROUND SOUND PROCESSOR) INPUT BUTTON

This button selects an external Surround Sound Processor
(SSP) input signal. When selected all preamp functions
are completely disabled. The only way to deselect SSP
mode is to press the SSP button a second time.

E HEADPHONE INPUT JACK

The Headphone Jack accepts 1/4” stereo headphone
plugs. Upon insertion of the headphone plug, the main
amplifier outputs are disabled. All other preamp functions
remain operational. Removal of the headphone plug
restores the main output signal.

F TAPE/EPL (EXTERNAL PROCESSOR LOOP)-

SOURCE BUTTON

When this button is in the SOURCE position (button is
not depressed) the signal is routed through the
Selector Switch (A) to the Tape/EPL Output (R).
Listening and taping is done in this mode. When the
button is depressed, the source signal is taken from a
tape or processor source through the Tape/EPL Inputs
bypassing the selector switch.

G INFRA RED RECEIVER

The Infra Red signal from the Pre 2L’s remote co
is received here, to operate the Volume, Mute an
SSP controls.

H L E D

When the LED is lit the Pre 2L is “ON”, receiving
power. When the Power Button (K) is depressed
LED will be dimly lit Green. After the power-up de
has timed-out (approx. 40 seconds) the LED will
bright green. Upon activating the SSP button (D),
LED will be lit orange. When in Mute mode the in
LED will flash ON-OFF at approximately 1 second in

I MONO/ST EREO BUTTON

When in the ON position (button depressed), the
Mono function is enabled. This function sums all
selected input signals together, and directs them
both channels. As long as the button is depresse
left or a right mono signal will be sent to both cha
of the preamplifier. All other preamplifier functions
operate normally.

J M U T E - O P E R ATE BUTTON

When in the OPERATE state, this button will allow
normal function. When in the MUTE state, the mu
signal is prevented from reaching the Outputs (Q
indicate a muted condition, the indicator LED (H)
flash OFF-ON at approximately 1 second intervals

Please Note that Muting does not work wh
SSP Mode.

K ON-OFF B UTTON

When in the ON position (button depressed), line v
is received by the Pre 2L circuitry from the AC so
Due to the warm up characteristics of tubes, it w
take 40 seconds for the tubes to pass signal. It is
suggested that the Volume be turned down for th
first minute. After the power-up time-out (approx
sec.) set the desired volume level. When in the O
position (not depressed), the Pre 2L is not receiv
power and is not operational.
