7 - Protection systems
Because Audiophony knows what sound professionals
need, our Ti amplifiers are equipped with many protection
systems to guarantee the best possible lifespan for the
internal components of your amplifiers and all devices
connected to their outputs.
- SoftStart System
Upon activation of your amplifier or activation of one of the
protection system, the Softstart system will slowly increase
the output so the speakers will not have to deal with sudden
peaks.
Thermal protection
-
The thermal protection circuit will open output relays in case
of excessively high temperature.
The Protect LED lights up during this process. In the power
transformer temperature gets too high, its temperature
sensor will disconnect all power outputs, The Protect
and Clip LEDs will light up while the ON LED lights off.
Cooling fans will continue operating at low speed and your
amplifier will be fully functional again once an acceptable
temperature has been reached.
Important note about the Bridge mode
1 - In Bridge mode, the load impedance must never go below 8 Ohms.
By connecting 2 x 8 Ohms speakers in parallel mode on a single output, this output will
have a 4 Ohms impedance.
To determine the impedance connected to an output, please proceed as follows:
In case of 2 x 8 Ohms speakers:
CHARGE = 1/(1/8 Ohms + 1/8 Ohms) = 1/ (0,125+0,125) = 1/0,25 = 4 Ohms
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 your speakers.

- Short-circuits
This protection takes effect upon detection of a short-circuit
via one of the output (defective loudspeaker, poorly isolated
speaker cable, etc.).
This system detects short-circuits such as excessively low
impedances and reduce the voltage output of your amplifier
to prevent the destruction of power transistors.
Affected outputs will be disconnected by the thermal
protection system if the short-circuit continues.
- DC Offset protection
The output relays will open automatically to prevent damage
to your speakers if one of the channels detects direct
current via one of its output connectors.
- Ultra-low frequencies (<40 Hz)
The internal high-pass filter gets rid off ultra-low
frequencies. However, if such frequencies were to be
detected, a relay will eliminate them.
