PA300+UHF Shown

Recommended Set-up Procedure

Ideally volume on the unit should be set at maximum before the microphone volume is adjusted to the desired level.
Turn on the main power switch and use either a wireless microphone or cabled microphone to adjust the volume.

Operating The Sound System

• Place the PresentationPro at its desired location.

• CAUTION: Assure the 120/240 switch is in the correct position.

• Plug the power cord into a grounded 120 volt, 60 Hz outlet.

• Connect and audio source. Plug 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.

• Turn the power switch “ON” (the red LED on the rear panel should light).

• Adjust volume (press the Vol+/Vol- on the rear panel or keys on RC-300 remote control), bass/treble controls for desired sound.

• Point the remote control at the speaker grill).

Wireless Receiver (PA300+UHF only)

a) Set the volume controls on both the UHF receiver and the mic to 10 o’clock.
b) If using only neckband or clip on mics, it is recommended that the mic volume on the M316 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.
c) 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.

Wireless Receiver (PA300+UHF only) continued from page 2

d) It is very important to ensure that the channel number selected on the PA300+UHF is the same as the channel
number selected on the mic. The channel indicator can be found on the Belt Pack Transmitter (M316) in the
case of neckband & clip on wireless mics & on the handle of the wireless handheld mic.
e) It is advisable to ALWAYS have spare batteries handy for the Belt pack Transmitters and Handheld radio mic.
Nothing is more embarrassing than to have them wear out during a presentation & not having spares on hand.
f) 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 (read more on page 4).
g) 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.

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 PA300+UHF.

Volume Control

When the main power switch is turned on, the Volume Control is at the lowest level to prevent accidental damage to
the amplier. The volume can be controlled by using the Vol+/Vol- buttons on the rear panel or the RC-300 Infrared
remote volume control. Volume is adjusted (+/- 4.5dB) with each push of one of the volume control buttons. Maximum
volume is reached after approximately ten pushes.

The remote control must be used in front of the speaker as the sensor is behind the speaker grill. The volume control
eects 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”.

Line Out

The ¼” line out is used to connect to the input of another piece of equipment such as a another amplied speaker. The
outputs are monaural and volume level will depend on the volume of the source. For example, the tape or CD player
level is controlled by the tape/CD volume control. Line out is independent of the Volume Control.

Tone Controls

The separate base and treble controls provide a wide range of adjustment for increasing or decreasing either the bass or
treble from “at” frequency response. The center or “12 o’clock” position is at.

Mic Input (Unbalanced)

An unbalanced, low impedance microphone input. For use with standard dynamic microphones that have a 1/4” phone plug.

Mic Input (Balanced)

Use this input for a dynamic (low impedance) microphone with an XLR plug. Condenser/electret (high impedance)
microphones which may need phantom (polarizing) voltage.

Mic Impedance Switch

This switch is used to compensate for mic impedance dierences. It assures full amplier output regardless of the
microphone used. Note: All connections must be made with shielded cable to avoid hum, buzzing, or radio interference.

LED

There are 3 LED indicator lights behind the speaker grill to give visual assurance of power, RF and audio reception.

Feedback Information

What is Feedback? Feedback is a ringing, howling, or shrill sound that is self-generated by the sound system when
using a microphone. It is the result of sound from the speakers being picked up by the microphone(s) in use and then
re-amplied by the system. This can form a self-sustaining loop that can damage the sound system if allowed to
continue, not to mention annoyance to persons nearby.

How to prevent feedback

ALWAYS STAND BEHIND THE SPEAKER WHEN USING A MICROPHONE. If feedback does occur, immediately reduce the
volume. Always plug in the microphone before turning on the power. Reducing the “treble” control may also help.
