Introduction

Congratulations on your purchase of the Phonic MAR 1 Reference Amplifier. Like other

Phonic MAR series power amplifiers – MAR 2/4/6, this unit is designed to provide a good

combination of power, audio clarity, reliability and durability. Especially, optimized for

studio monitoring applications and moderate-power live performance setups, the amps

main features include:

l 150 watts per channel into 4 ohms, 100 watts per channel into 8 ohms

l Front panel LED Indicators for Protect, Clip & Signal

l Detented dB gain controls

l Built-in protection system for short circuit, DC, and temperature monitoring

l Power-up muting

l -26dB signal presence LEDs on each channel

l Quality Neutrik combo Input connectors for professional use

l Stereo/Parallel switch

l Ground floating switch

l Massive, custom-designed extruded heat sinks ( individual for each channel) for

cool operation

l No Ventilation fan is needed, allowing for quiet operation and reduced ambient noise

in the studio.

l Extremely low noise and distortion, suitable for quiet applications such as recording

studio, church and museum.

Precautions

1. When first powering-up the amp, keep the amplifier Gain Controls all the way off, in

order to block potentially damaging or annoying sounds caused by defective cables or

hookups. When turning up the Gain, do it gradually, until normal operation is verified.

These precautions are necessary with all high-power amplifiers, since they have

enough power to blow most speakers in abnormal situations.

2. Check the AC Voltage before connecting the AC plug.

3. The amplifier is protected from surges in power-line voltage by the fuses. Should your

unit ever fail to power-up, first unplug the power cord, and then replace the fuse with

exact type and value.

About This Manual

Please be reminded that a power amplifier is a high-current, high-power device

and should be treated with respect and care. Please read this manual before

connecting and operating your unit and file it in a safe place for future reference.
