Plug microphone into shock mount on reading surface.
Turn main power switch located under reading surface
on. Rotate "MAIN MIC", "TREBLE" and "BASS" controls
fully counterclockwise to minimum volume position.
Turn speaker switch located on dash panel to "on" posi-
tion. While speaking into the microphone, slowly in-
crease "MAIN MIC" volume by turning knob clockwise.

POWER
Connect power supply to 110/120 VAC 3-wire outlet
(220/240 VAC models to 220/240 VAC source).
READING LIGHT
Depress light switch to activate light. ADJUST VISOR
AS NECESSARY. Use GE 25T8DC 110v appliance lamp
or equivalent when relamping all 110/120 sound and
non-sound lecterns; GE 1176 12v for 220v lecterns.
DIGITAL CLOCK/COUNT DOWN TIMER
Select desired mode; adjust time with SET switch. Unit
will remain operational as long as the main power supply
is on. NOTE: Power interruptions will cause the clock
to flash until reset.
ALL MODELS
OPTIONAL HEIGHT ADJUSTMENT
Models with optional reading surface adjustment are
controlled by the switch marked HEIGHT and provide up
to 8 - 9 inches of elevation. To raise or lower, depress
HEIGHT switch.
SOUND MODELS
Adjust until feedback begins, then decrease volume to
stable condition or lower to desired volume level. Adjust
bass and treble controls to desired tonal quality. Turn
SPEAKER SWITCH to "off" position when done using the
sound system.
AUXILIARY MICROPHONE (XLR JACK)
The auxiliary mic input is located under the reading sur-
face and is used for a second mic or wireless micro-
phone input. The volume control is located on the dash
panel. The aux. mic input is balanced low impedance
(600 Ω) and is phantom powered so condenser type mi-
crophone can be used.
AUXILIARY LINE INPUT (1/4" PHONE JACK)
The auxiliary input is used for playback of tape player,
musical instrument, VCR, or an audio feed from another
sound system. The volume control is located on dash
panel.
AUXILIARY LINE OUTPUT (1/4" PHONE JACK)
The signal output is a composite of all the inputs and
can be fed directly to an audio or video tape recorder. Or,
the line output can be fed to another sound system to
combine systems for greater output, or it may be fed to
the input of a hearing impaired system.
EXTERNAL SPEAKER OUTPUTS (1/4" PHONE JACK)
The external speaker outputs can be used to drive exter-
nal speakers in lieu of the internal lectern speaker. When
a plug is inserted into the external speaker jacks, the in-
ternal speaker is disconnected. The powerful (50 watts)
is adequate to drive several speakers provided the total
load impedance is not less than 2 ohms. The output of
the amplifier is self-protecting against overload; how-
ever, low impedance loads (below 2 Ω) will cause exces-
sive heating reducing amplifier output.
