USER’S MANUAL

POWER SUPPLY
Ensure that the insource voltage (AC outlet) matches the voltage rating of the product. Failure to do so could
result in damage to the product and possibly the user. Unplug the product before electrical storms occur and
when unused for long periods of time to reduce the risk of electric shock or fire.
2
EXTERNAL CONNECTION
Always use proper ready-made insulated mains cabling (power cord). Failure to do so could result in
shock death or fire. If in doubt, seek advice from a registered electrician.
FUSE
To prevent fire and damage to the product, use only the recommended fuse type as indicated in this manual. Do
not short-circuit the fuse holder. Before replacing the fuse, make sure that the product is OFF and disconnected
from the ACD outlet.
PROTECTIVE GROUND
Before turning the unit on, make sure that it is connected to Ground. This is to prevent the risk of electric shock.
Never cut internal or external Ground wires. Like wise, never remove Ground wiring from the Protective Ground
Terminal.
OPERATING SAFETY INSTRUCTIONS
Read these instructions. Follow all instructions. Keep these instructions. Do not discard. Heed all warnings. Only
use attachments accessories specified by the manufacturer.
This symbol indicates that the disposal of this product is submitted to local regulations. Please
contact your local dealer.

Important Safety In truction
This symbol, wherever used, alerts you to the presence of un-insulated and dangerous voltages
within the product enclosure. These are voltages that may be sufficient to constitute the risk of
electric shock or death.
This symbol, wherever used, alerts you to important operating and maintenance instructions.
DO NOT REMOVE ANY COVERS
Within the product are areas where high voltages may present. To reduce the risk of electric shock do not
remove any covers unless the AC mains power cord is removed. Covers should be removed by qualified service
personnel only. No user serviceable parts inside.
POWER CORD AND PLUG
Do not tamper with the power cord or plug. These are designed for your safety. Do not remove Ground
connections! If the plug does not fit your AC outlet seek advice from a qualified electrician. Protect the power
cord and plug from any physical stress to avoid risk o electric shock. Do not place heavy objects on the power
cord. This could cause electric shock or fire?
SERVICING
Refer all servicing to qualified service personnel only. Do not perform any servicing then those instructions
contained within this User’s Manual

Introduction

Thank you for purchasing Audiopole FORCE 700. This professional class-D amplifier can deliver 700 W and
weighs only 4.5 kg.
STEREO mode is a standard stereo amplifier that delivers 2 x 200 W 8 Ohms or 2 x 350 W 4 Ohms. The
BRIDGE mode allows you to get 700 W 8 Ohms securely. Finally, the PARALLEL mode allows to amplify a
mono source using the resources of amplification of the 2 channels. The device features a choice of
connectors that adapt easily to most of uses. So the balanced XLR inputs are doubled by unbalanced RCA
jacks and the speaker outputs have secure SPEAKON terminals.
•2 x 350 W 4 Ohms, 2 x 200 W 8 Ohms
•700 W 8 Ohms (BRIDGE mode)
•Class-D amplification
•Weight 4.5 kg
•3 operation modes: STEREO - BRIDGE - PARALLEL
•Balanced XLR inputs, unbalanced RCA inputs
•SPEAKON and Output screw terminals
•2U rack

Control & Setting

1 – POWER
Power ON OFF switch. Before any action, turn the potentiometers (2) and (3) to maximum attenuation (- ∝).
The start is protected by a 7 second delay.
2 – CHANNEL 1
Channel 1 input signal attenuator.
Increasing the level is done by turning the knob in a clockwise direction.
3 – CHANNEL 2
Channel 2 input signal attenuator.
4 – SIG
Channel 1 signal indicator.
The intensity of the Green Led varies depending on the level of the input signal.
5 – SIG
Channel 2 signal indicator.
6 – CLIP/PROT
Channel 1 clipping signal.
The red Led, provides information about the state of the input signal. Normally, it should illuminate only
occasionally. If the light stays on, the input level is too important and there is a risk of distortion. So adjust the
level with the attenuators (2) and (3) or decreases the source volume.
7 – CLIP/PROT
Channel 2 clipping signal.
8 – BRI POW
BRIDGE mode indicator power.
The two-color LED lights up green when the amplifier is powered; It turns red when the BRIDGE mode is
switched on.

11 – MODE
Mode selector: PARALLEL – SREREO – BRIDGE, (see chapter 4).
Any action on this switch must be carried out with the amplifier off.
12 – OUT
Speaker outputs on screw terminals.
Check the cables tightness before use.
13 – OUT
SPEAKON outputs.
Do not use the binding posts and SPEAKON outputs simultaneously.
14 – Cooling fan
Do not obstruct the air input and exit of the amplifier cooling. Any impediment to the free movement of air in
the amplifier may cause a failure not covered by the warranty.
15 – AC INPUT
Plug in the mains cable. Before any connections make sure that the power cable is not damaged. The
connection to the mains supply must have an earth connection. The mains voltage supplied must conform with
the electrical characteristics of the appliance (see chapter 8).

Operation Mode
7
STEREO Mode
This is the standard mode: both channels functioning independently, the attenuators (2) and (3) respectively
controlling each channel input level. The recommended nominal load impedance is 8 or 4 Ohms per channel.
The speakers are connected to terminals or to the SPEAKON output connectors as shown in the figure below.
BRIDGE Mode
It is a monophonic mode, both channels work with the same signal input, but in phase opposition. It follows a
voltage output multiplied by two, and therefore issued two times more power on double load impedance.
ONLY channel 1 is used. The input signal is connected to input 1, both volume controls on the front panel must
be positioned on the same value: position 0 dB is recommended (at bottom right).
Be careful, speakers are connected to the red terminals 1+ and 2+ from the SPEAKON channel 1 connector.
Check that the load impedance is not less than 8 Ohms (see Chapter 7)

PARALLEL mode
In this mode the two channels of the amplifier receive the same signal connected to the input 1, two
attenuators (2) and (3) remaining active. The speaker outputs use identical to Stereo mode wiring.
In tallation Tip

In case of installation in cabinet or rack, ensure the ventilation requirements. The depth of the unit is 277 mm.
The dimensions in height is 2 units rack (89 mm).
Do not position audio high-gain equipment like preamplifiers or recorders just above or below the amplifier.
Despite the protections of the radiation device, magnetic fields can induce hum in unscreened ancillary
equipment. Do not obstruct the inputs and exits of air for the cooling of the amplifier. Any impediment to the
free movement of air in the amplifier may cause a failure not covered by the warranty.
The operation of the amplifier in an environment where the air is confined or polluted requires frequent internal
cleaning. Smoke and dust particles accumulated inside the appliance can cause failures not covered by the
warranty. This cleaning should be done by qualified personnel.
Before any work on the wiring, be sure to turn the control knobs fully counterclockwise and turn off the
amplifier.
Only use good quality speaker cables, unshielded.
Use good quality audio cables, shielded, for inputs. A balanced or unbalanced type connection is feasible.

Connector
9
Available on FORCE 700, input connectors are balanced (XLR) and unbalanced (RCA). Cables and fact
sheets related to connecting to other equipment must therefore be of the same nature. Are listed below types
of cords found in trade with their electrical connection diagram.

Unbalanced cable
Impedance Load
When connecting multiple speakers or speakers on the same channel, various types of connection are
possible. The type of installation changes the impedance of the load applied to the amplifier. Generally, when
this impedance decreases the power increases. It is therefore possible to obtain a greater power, but this is
limited by the characteristics of the amplifier. Knowledge of the load impedance is therefore crucial in order to
not cause trouble.
