INSTRUCTION BOOK FOR
Special Needs Lecterns
All Models
Power
Connect power supply to 110/120 VAC 3-wire outlet
(220/240 VAC models to 220/240 VAC source).
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 lash
until reset.
Height Adjustment
The reading surface adjustment is controlled by the switch
marked HEIGHT and provides 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” position. While speaking into the microphone, slowly increase “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 “of” position when done using the sound system.
Auxiliary Microphone (XLR Jack))
External Speaker Outputs (1/4" Phone Jack)
The auxiliary mic input is located under the reading surface
and is used for a second mic or wireless microphone 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 microphone 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.
The external speaker outputs can be used to drive external
speakers in lieu of the internal lectern speaker. When a plug is
inserted into the external speaker jacks, the internal 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 ampliier is self-protecting against
overload; however, low impedance loads (below 2 Ω) will cause
excessive heating reducing ampliier output.

If your lectern fails to operate on a known power source, be
sure to check the circuit breaker located on the Power Supply
for a tripped condition. Reset to restore function. If breaker
continues to trip, discontinue use of product until problem
can be diagnosed.
