4 ICON 300/700
INTRODUCTION
Congratulations on your purchase of the Phonic
Icon 300 or 700 power amplifier. The Icon Series is
a line of professional power amplifiers specifically
designed for contracting application. These two
models each has independent channels and is
available for driving 200V, 140V, 100V, 70V, 50V or
25V "constant voltage" lines. Each channel has its
own power transformer (toroidal type) secondary
to provide maximum audio separation (minimum
sound leakage) between two channels, minimizing
interaction that can otherwise occur on amplifiers
with a common power supply.
FEATURES

Automatic dual-speed, high efficiency fan
cooling

Rear panel detented gain controls for
security and resetability

Stereo, bridge or parallel operating
modes

XLR and barrier strip inputs

XLR in and outs for multiple amplifier
operation & easy signal pass-through

Fully short-circuit, temperature and DC
offset protection

Barrier strip connection determines output
mode - 25V, 70V, 100V and direct outputs
available simultaneously

Toroidal output transformers provide full
electrical isolation and meet worldwide
safety agency approval

Built-in 45 Hz subsonic filter prevents
speaker transformer saturation with
minimal effect on program material

Power-up muting
PRECAUTIONS
1. When first powering up the amp, keep the
amplifier gain controls all the 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 AV Voltage before connecting the
AC plug
3. Speaker Output Shock Hazard! The Icon
300 and 700 amps are capable of producing
hazardous output voltages. To avoid electrical
shock, make sure the cover is in place over
the output terminals, and do not touch any
exposed speaker wiring while the amplifier is
operating.
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.
