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. clip leD indicator (icon 300)
The LEDs light up at clipping status, whenever any conditions
occur that could cause problems for the amp, such as an outof-spec load and waveform distortion. Because of the Icon's
ability to enter and exit clipping with as few audible artifacts as
possible, you may not hear any distortion even if the indicator
ashes. In general, a few ashes every now and then will not be
a problem. However, if the LEDs ash often or remain on for any
extended period of time, then turn down the volume controls
to reduce the signal level going to the Icon amp. If this doesn't
solve the problem, check your output cables and speakers.
4.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.
5. limit leD indicator (icon 700)
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 (ie. output power is over 400W per channel), the limiter
momentarily reduces the input signal level, just enough to
prevent it. The limit LED lights whenever this occurs.
rear Panel DescriPtion
6. Gain controls
These two knobs and the level controls for channels one and
two respectively. Turning clockwise will increase its gain and
counter clockwise will decrease its gain. Please always powerup with the volume all the way down, and increase the volume
slowly to make sure that no conditions exist which could annoy
your audience or harm your speakers.
7. cH1/cH2 inputs (Xlr connectors)
These inputs are provided for making balanced connection to
mixers, preamps, etc. The XLR inputs are wired as per the
following convention:
8. Balanced Barrier strip inputs
These connection points provide the best option for permanent
or long-term installation. Connections should be screwed down
tight to exclude oxygen, and care should be taken to avoid loose
strands of wire that may cause short circuits.
9. CH1/CH2 Parallel Pass Through XLR Connectors
These XLR output connectors are provided for parallel
connection to another Icon or other amplier.
10. Stereo/Parallel/Bridge Switch
In stereo operation, two separate signals are treated separately
by channels 1 and 2 of the ampliers.
In Parallel operation, one signal is treated by bother channel
1 and 2 of the amplier. In other words, a signal connected to
Input CH1 (6) or CH2 (7) is sent to both Output CH1 (10) and
CH2 (11).
In Bridge operation, both channels are congured to drive a
single load with a single signal to CH1 (only CH1 is operative,
and CH2 input must be vacant) at twice the power.
This switch should only be used when the Amplier is off;
otherwise the speakers' components could be damaged.
11. Direct output connectors, cH1/cH2
These are barrier strips to connect low impedance speakers.
Spade lugs and bare wires should both be screwed down tight
to exclude oxygen, and care should be taken to avoid loose
strands of wire that may cause short circuits.
12. audio transformer outputs, cH1/cH2
These are barrier strips to connect distributed line (25V, 70V,
100V, 140V and 200V). Spade lugs and bare wires should both
be screwed down tight to exclude oxygen, and care should
be taken to avoid loose strands of wire that may cause short
circuits.

Balanced connection - Attach as shown. Connect the (+) wire
and ground wire to terminal pins as marked.
Direct low impedance:
Unbalanced connection - Attach input signal wires as shown.
Use the non-inverting (+) input and the ground terminals of the
header, and also connect a wire jumper between the inverting
(-) input and the ground terminal. The wire jumper will prevent a
reduction in gain caused by a oating unbalanced input.
Input sensitivities - - Audio signals of these levels will produce
full rated output power at 8 ohms.

barrier Strip Output Connections
Barrier strips located on the rear panel allow speaker cable
connections to the amplier output. See the diagrams for
details on connecting speakers and/or distributed (23-, 70-,
or 100-volt) lines. Insulated connectors of the type shown are
recommended.
Always make sure the amplier is turned off before you
change any output connections.

Bridge Mono Conguration for Direct Outputs
1. Set into bridge mode
2. Connect the signal to channel 1's input only. Do not
connect an input signal to channel 2.
3. Use on channel 1's gain control to set the level. Both
channels' signal and clip indicators should ash identically
when the amplier is operating.
audio Transformer Outputs
Make sure the sum of the power settings of all the speakers
does not exceed the power rating of the amplier. It is a good
practice to allow a 20% safety margin. For example, if the
amplier has a power rating of 300W, it is always a good idea to
make sure the sum of the loudspeaker loads on the distributed
line is 240W or less.
25 volt line output connection
Loose screw terminals, insert wire connectors under screws.
Tighten screw terminals.
50 volt line output connection

Bridge Mono Conguration for Audio Transformer Outputs
1. For driving 140V or 200V distributed lines, the amplier must
be set into bridge mono mode.
2. Connect the signal to channel 1's input only. Do not
connect an input signal to channel 2.
3. Use only channel 1's gain control to set the level. Both
channels signal and clip indicators should ash identically
when the amplier is operating.
Parallel Mono Conguration
The "Parallel mode" ties the two channel inputs together so
that both are driven by the same signal, without the need for
external jumpers or wiring. After the inputs, both channels
operate independently. Though they carry the same signal, their
gain controls affect only their respective channels, which must
be used separately. Please refer to the previous Rear Panel
Description. Never parallel the speaker outputs.
Low-Impedance and Distributed Speakers on Icon
Ampliers
If your application calls for connection of an 8 ohm speaker and
a distributed line to the same amplier channel, the Icon 300
and Icon 700 are among the very few ampliers that can do
that. However, since most of the audio power is drawn by the
direct-connected speaker, you must derate the distributed line;
and the distributed line should have a total power load of no
more than one-fourth of the ampliers normal distributed line
power rating.
Computing maximum allowable distributed line load with a
known low-impedance load
MaxTOP = [MaxRatedPL - ((2 x MaxRatedPL)/Impedance)]/2
MaxTOP is the sum of the power taps of the speakers connected
to the Audio Transformer outputs.
MaxRatedPL is the maximum rated power of the amplier into
a two ohm load.
Impedance is the load impedance connected to the direct
outputs.
Example: One channel of an Icon 700 has an 8-ohm load
connected to the Direct (low impedance) output. Then the
maximum power left available to drive a distributed line is:
140 volt line output connection,
bridge mono mode
200 volt line output connection,
bridge mono mode
MaxTOP = [550-((2x550/8)/2)] = 206 Watts
