ALL MODELS

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.

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

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.

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 (

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 (

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 (

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.
