4.1 - Front panel
[1] - Mounting brackets
Allow you to insert your amplifier into 19" (482 mm)
[2] - Cooling vents
Wi series amplifiers (apart from the Wi640) are
equipped with two fans located at the rear.
The air flow goes from the rear to the front and
lowers the temperature of internal components.
Never obstruct these vents and clean them on a
regular basis to make sure your device benefits from
the longest possible lifespan.
[3] - Power Button
Activates the device.
[4] - Signal LEDs
These green and yellow LEDs light up when an
incoming signal is detected.
[5] - LED Clip
Lights up when the clip threshold has been reached,
to indicate the input is saturated and the outgoing
signal distorted.
Adjust the output level of your source to go back to
adequate sound levels and prevent serious damages
to your speakers and amplifier. The sound quality
will be highly improved as well.
Note : Wi amplifiers feature 2 identical
channels (1 and 2), the description below
only refers to one channel for legibility
[6] - On LED
This blue LED lights up when the amplifier is
connected to an electrical outlet and the power
switch positioned onto ON.
[7] - Protect LED
This LED lights up to indicate the channel is in
protection mode, the output signal is interrupted by
an internal relay. The protection mode is activated
when the channel is overheating or a serious
problem has been detected. Its aim is to protect the
speakers connected to the channel in default.
Usually, this LED briefly lights up upon activation of
your device but should light off quite slowly. This is
to protect your speakers against current peaks when
your amplifier is initialising.
[8] - Input attenuator
Each channel features an input attenuator allowing
you to limit the incoming signal level.
This attenuator features 21 notches. On its left, it
attenuates the incoming signal by 80dB, on its right,
the signal is not attenuated and the amplifier works
at full power. When activating the "mono bridge"
mode, attenuator 1 only will affect the sound level,
whereas each attenuator adjusts the sound level of
the corresponding channel in "Parallel" mode.

[1] - Cooling fan
The air flow goes from the rear to the front and
lowers the temperature of internal components.
Never obstruct these vents and clean them on a
regular basis to make sure your device benefits from
the longest possible lifespan.
[2] - Combo input socket
This connector allows you to power up your
amplifier with a line-level signal. It is fully compatible
with both symmetrical and asymmetrical signals
but we recommend, whenever possible, to use
asymmetrical signals as it will help you getting rid of
parasitic noises when using low-quality cables. This
connector can also be used to connect Jack 6.35
TRS and male XLR plugs. Polarities are spread as
- Pin 2 (Tip) = Signal +
- Pin 3 (Ring) = Signal - Pin 1 (Sleeve) = Ground
[3] - Link connector
Allows you to send the incoming signal to another
[4] - HPF (High Pass Filter) switch
When "ON", the incoming signal is filtered.
Frequencies below 40 Hz are disposed of. This
function allows you to get rid of parasitic noises and
send a signal appropriate to the broadband of your
loudspeakers. When "OFF", a filter still eliminates
frequencies below 5 Hz to protect the input of your
amplifier against direct currents.
[5] - Switch Limiter
Activates the "Limiter" function allowing you to
automatically reduce the sound level of excessive
signals and prevent them from being distorted.
[6] - Parallel / Stereo / Bridge Selector
Allows you to select the operating mode of your
- Stereo: Standard mode, each channel amplifies
the signal currently received.
- Parallel:The signal sent to input 1 is amplified in
a similar manner by both channels.
- Bridge: The two amplification channels are
added and only the input 1 signal is amplified.
[7] - Output via terminals
Allows you to connect speakers via a cable with
terminals plugs, or directly connect stripped cables.
In "Bridge" mode, use the red terminals to connect
your speaker.
[8] - Output via Speakon® connector
Allows you to connect speakers via a cable with
SpeakOn® connectors. More details about wiring
are available in next chapter.
[9] - Circuit breaker
Turns off the power supply in case of mains failure or
voltage overload. Press it again to reactivate it.
[10] - Power input
Connect here the supplied power cord to power up
your amplifier.

Wi series amplifiers feature multiple protection
systems born from Audiophony's long experience
in professional sound solutions, to ensure the
best possible lifespan and protect the internal
components of your device and connected sources.
- SoftStart system
The SoftSart protection system gradually powers up
your unit upon activation in order to preserve your
- Thermal protection
In case of overheating, the thermal protection will
open output relays. The Protect LED will light up
during this process. If the power transformer is also
overheating, its temperature sensor will disconnect
all power outputs, the Protect and Clip LEDs will
light up while the "On" LED will turn off. The cooling
fans will operate at lower speed.
Your device will be fully operational again once the
standard temperature has been reached.
7 - Protection systems
- Short-circuits
In case of short-circuit (defective loudspeaker,
poorly isolated cable, etc.) this system will
automatically protect the amplifier. This system
detects short-circuits such as too low impedances
and reduces power stages levels. If the short-circuit
remains, all outputs will be disconnected by the
thermal protection system.
- Direct current protection
Whenever a channel detects a direct current
via its output connectors, all output relays will
automatically open to prevent damages to your
- Very low frequencies (<40 Hz)
The internal high-pass filter gets rid of very
low frequencies. Despite all that, whenever an
excessively low frequency is detected a relay will
deactivate the output.
Important note about the Bridge mode
1 - In Bridge mode, the load impedance must never fall below 4 Ohms.
For the record, connecting 2 x 8 Ohms speakers in parallel on one of the amplifier
output will result in a 4 Ohms load for this output.
Calculating the impedance connected to an output can be done as follows:
Let us return to our 2 x 8 Ohms speakers:
LOAD = 1/(1/8 Ohms + 1/8 Ohms) = 1/ (0.125+0.125) = 1/0.25 = 4 Ohms
This clearly demonstrates you cannot add an extra speaker connected in parallel to
this bridged output without falling below a 4 Ohms impedance.
2 - In stereo mode the minimum impedance is 2 Ohms: 4 x 8 Ohms speakers
connected in parallel per side.
3 - Never connect the ground of the cables of your speakers.
