1ICON300 / ICON700
INTRODUCTION
Congratulations on your purchase of the Phonic Icon 300 or 700
power amplier. The Icon Series is a line of professional power
ampliers specically 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 ampliers
with a common power supply.
FEATURES
● Automatic dual-speed, high efciency 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 amplier 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 lter prevents speaker transformer
saturation with minimal effect on program material
● Power-up muting
PRECAUTIONS
1. When rst powering up the amp, keep the amplier 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 veried. These precautions are necessary with
all high-power ampliers, 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 amplier is operating.
ABOUT THIS MANUAL
Please be reminded that a power amplier 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 le it in a safe place for future reference.
FRONT PANEL DESCRIPTION
1. Power Switch
The power ON/OFF switch with an LED indicator.
2. Protect LED Indicator
The Icon 300/700 features several types of protection to prevent
damage to the circuitry during turn-on or fault conditions. If the
LEDs light up, this indicates that one of the various protections
is safeguarding the different sections of the amplier and in
these cases, the power output is normally switched off until
normal operating conditions are restored.
Loudspeaker protection: the power-on protection relay
prevents damaging thumps to the speakers as the power
comes on. When the amp is switched on, the protect LED
will light for a few seconds, and then go out, indicating that
the relay has closed.
Thermal protection on the heat sink: If the amp overheats,
thermal shutdown protects the circuitry until the temperature
is reduced to a safe level.
Short circuit protection: The Protect LED Indicator will also
light up if the speaker terminals are short-circuited, or the
impedance of the load is too low. In these circumstances,
the Protect LED will stay on until the fault conditions are
rectied.
Some protection situations require the amplier to be
switched off and then back on for normal operating
conditions to be restored.
3.Signal “Status” LED Indicator
Each channel of the Icon 300/700 features a signal LED to show
that there is an audio signal at the input to the channel. The
threshold for the indicator is -26dB, which should be enough to
avoid noise triggering the LED.
4. Limit LED Indicator
The Icon 700 has a built-in limiter on each channel to prevent
clipping. Should the signal reach a level high enough to cause
clipping, the limiter momentarily reduces the input signal level,
just enough to prevent it. The limit LED lights whenever this
occurs.
1. Read these instructions before operating this
apparatus.
2. Keep these instructions for future reference.
3. Heed all warnings to ensure safe operation.
4. Follow all instructions provided in this document.
5. Do not use this apparatus near water or in locations
where condensation may occur.
6. Clean only with dry cloth. Do not use aerosol or liquid
cleaners. Unplug this apparatus before cleaning.
7. Do not block any of the ventilation openings. Install
in accordance with the manufacturer
’
s instructions.
8. Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including
.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug
has two blades and a third grounding prong. The wide
blade or the third prong is provided for your safety. If
the provided plug does not into your outlet, consult
an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or
pinched particularly at plug, convenience receptacles,
and the point where they exit from the apparatus.
11. Only use attachments/accessories by the
manufacturer.
12. Use only with a cart, stand, tripod, bracket, or
table by the manufacturer, or sold with
the apparatus. When a cart is used, use caution
when moving the cart/apparatus
combination to avoid injury from tip-
over.
13. Unplug this apparatus during lighting
storms or when unused for long
periods of time.
14. Refer all servicing to service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
