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 amplifier. 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 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”.

Line Out

The ¼” line out is used to connect to the input of another piece of equipment such as a another amplified 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 “flat” frequency response. The center or “12 o’clock” position is flat.

Mic Input (Unbalanced)

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