1. General Description

1.1

MP69 series power amplifiers are a type of PA conference devices that integrate the equalizing

function, frequency shift function, front and back stage amplification function. The products

provide 4 audio source input ports, 6 microphone input ports, a line output port and 4 power

amplifier's output terminals, etc. Among them, you can select one audio input from 4 channel

audio input ports and control it's volume. The volume of the 6 microphones can be controlled

independently. A master-volume control is provided for controlling the total output volume. The

7-band equalizers (EQ) have been provided to adjust the output. The shifted frequency of

microphones is 0-5Hz higher than the original frequency.

MP69 series products have rated voltage outputs of 100 V, 70 V, and rated resistance outputs of 4

Ω, 8 Ω, 16 Ω. They are divided into four kinds of power model 60 W(MP6906), 120 W(MP6912),

250 W(6925) and 350 W(6935).

The products are designed according to the requirements of the conference hall having no whistle,

with the tone loud and clear and the volume adjustable. The products provide with multiple

protection, well-found function and with the stable operating state and can meet the requirements

of conference site for the sound amplification and the background music.
