Auxiliary Inputs
Two auxiliary inputs are provided for connecting audio from laptop computers or multimedia players.
Output level is adjusted by the auxiliary volume control located above the AUX IN.
Auxiliary / Line Out
Addtional powered speakers can be connected to the PL-19 from the RCA/LINE OUT.
Connections and Functions
NOTE: When first connecting other equipment to the “AUX-IN” make certain that their power is off and
volume control at minimum.
Recommended Set-up Procedure
1. Volume on PL-19 should be set at maximum before the microphone volume is adjusted to the de-
sired level.
2. Turn on the main power switch and use either a wireless microphone or cabled microphone to
adjust the volume.
Operating the Sound System
1. Place the Lectern at its desired location.
2. Plug the power cord into a grounded 90-240 volts AC, 50-60Hz.
3. If using a microphone into either the XLR MIC input jack or the ¼” phone mic input or a wireless
Califone microphone. An audio source can be plugged into the AUX or LINE IN jacks.
4. Turn the power switch “ON” (the red LED on the rear panel should light).
5. Adjust volume (press the Vol+/Vol- on the rear panel, bass/treble controls for desired sound.
6. Point the remote control at the speaker grill.
The PL-19 accepts one
wireless mic and combo
¼”/XLR in addition
to the gooseneck mic
built into the desktop.
If connecting either a
wireless or wired mic
to the PL-19, do not
turn the amplifier on
until all input & output
connections have been
made.
Wireless Receiver
1. Set the volume controls on both the UHF receiver and the mic to 10 o’clock.
2. If using only neckband or clip on mics, it is recommended that the mic volume on the M319 Belt
Pack Transmitter (not the UHF receiver) is turned to maximum. The volume control on the Belt Pack
Transmitter can then be used to adjust the mic volume.
3. If using mics which DO NOT have individual volume controls it is recommended that the microphone
volume control be set at 10 o’clock and then re-adjusted to the desired volume as required.
4. It is very important to ensure that the channel number selected on the Lectern Control Panel is the
same as the channel number selected on the mic. The channel indicator can be found on the Belt Pack
Transmitter (M319) in the case of neckband & clip on wireless mics & on the handle of the wireless
handheld mic.
5. It is advisable to ALWAYS have spare batteries handy for the Belt Pack Transmitters and Handheld radio
mic.
6. Nothing is more embarrassing than to have them wear out during a presentation & not having spares
on hand.
7. If a mic is being used within 4 to 6 feet from the front of the speaker this will produce what is known as
“feedback “ - a shrill screeching sound. Ensure the operator is far enough away to prevent this (

).
8. The wireless microphones can be used up to 150 feet from the main unit. N.B. The channel numbers are
preset at the factory so unless anyone tampers with them there is no need to worry.
9. If using the wireless receiver, make sure the frequency is set on the Califone wireless mic or transmitter
to the same matching frequency on the Lectern Control Panel.
Volume Control
1. When the main power switch is turned on, the Volume Control is at the lowest level to prevent
accidental damage to the amplifier.
2. The volume can be controlled by using the Vol+/Vol- buttons on the rear panel. Volume is adjusted
(+/- 4.5dB) with each push of one of the volume control buttons. Maximum volume is reached after
approximately ten pushes.
NOTE: The remote control must be used in front of the speaker as the sensor is behind the speaker grill.
The volume control effects the loudness of both wired and wireless microphones.
Line Inputs
The line-level RCA input jacks can be used with audio sources such as computers, DVD players, LCD
projectors, CD players or connecting another wired PresentationPro. (The L+R stereo outputs to a mono
signal without the need for adapters.)
NOTE: For wireless microphone operation, the wireless receiver audio output can be plugged into “Line-
In”.
