Da-Lite Multi-Media Lectern - Manual (Page 2)

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
“off”
position when done using the sound system.
Auxiliary Microphone (XLR 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.
External Speaker Outputs (1/4" Phone Jack)
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 amplifier is self-protecting against
overload; however, low impedance loads (below 2
Ω) will cause
excessive heating reducing amplifier output.
Set-Up
Sound 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.
Installing Computer Monitor
The reading surface is hinged to allow access to the inside of the
lectern. Open the keyboard door and release the latch on the
reading surface and lift.
The cables can be routed through the holes in the shelves.
Close the reading surface carefully to make sure the glass does
not hit the monitor.
