Function description

Amplifier

INPUT1, INPUT2 and INPUT3 Level control

These knobs are designed for volume level controlling.

TONE CONTROL

These knobs are used to attenuate a high and low frequency. High frequency can by adjusted in ±10dB range at 10kHz point, low frequency can by adjusted in ±10dB range at 100Hz point.

PEAK INDICATOR

If signal in the input or output is clipping this LED starts blinking.

SIGNAL INDICATOR

This LED indicates the audio signal in the input.

POWER INDICATOR

This LED lights if amplifier is on.

POWER SWITCH

By using this switch amplifier can be turning on and turning off.

POWER CONECTOR AND FUSE

Power connector is designed for main powers connecting to amplifier. This connector is combined with fuse holder and 1A, 250V fuse.

OUTPUT TERMINAL

This terminal is designed to connect audio line in to amplifier. There are available 4 types of output: low impedance 4Ω output, low impedance 8Ω output, 70V output and output for 100V audio line. Please find same connection examples below.

There is possibility to connect external power supply, external battery etc. Please find the connection example.

REC OUTPUT

This line level output is designed for recording.

AUX INPUT

This is line level audio input, designed for connecting external CD player or FM/AM tuner to amplifier.

BALANCED INPUT1, INPUT2 ,INPT3

These balanced phoenix inputs are universal, the sensitivity of this inputs are selectable by DIP switch.

When microphone sensitivity is selected phantom power can be activated by using phantom power switch. Please note: Phantom power will be activated in all inputs at same time. INPUT1is priority input.

Priority level can be controlled by MUTE LEVEL knob.

MONITOR OUTPUT

This output is designed for audio monitoring. There are two types of output, first for the speaker (1W/8Ω) second for earphones etc. (1V/600Ω) connecting. The volume of this output can be controlled by level knob. This knob is located near the output connectors

TEL INPUT

Emergency input (from PBX station etc). The volume of this input can be controlled by level knob. This knob is located near the TEL input connectors.

DIP SWITCH

By using DIP switch you can set input gain and turn on/off phantom power. When 1-3 switch is set to the

ON position inputs sensitivity is suitable for line level input. When 1-3 switch is set to the OFF position inputs sensitivity is suitable for microphone level input. When switch No 4 is set to the ON position

Phantom power (15V DC) is available in all microphone inputs.
