Turn-on/turn-off muting

The amplifier outputs are muted for a couple of seconds after turn-on, and immediately at turn-off.

Short circuit protection

The Output Averaging™ circuit protects the output devices from short circuits and stressful loads.

Clip limiting

During normal operation, the clip limiter does not affect the audio signal and is, in fact, inaudible. It will allow brief clipping of peaks, activating only when continuous, hard clipping occurs. The clip limiter will then reduce the audio signal (up to 10dB) to minimize clipping. When clipping ends, the clip limiter will deactivate and cease its gain reduction.

Mise en sourdine lors de

la mise sous/hors tension

Les sorties sont coupées pour quelques secondes quand on allume l’amplificateur, et immédiatement quand on l’éteint.

Protection contre les

court-circuits

Le circuit Output Averaging™ protège les transistors de sortie contre les court-circuits et les charges difficiles.

Limiteur d'écrêtement

En utilisation normale, le limiteur d'écrêtement n'affecte pas le signal audio et il est en fait inaudible. Il permet l'écrêtement des transitoires et n'entre en action que lors d'écrêtement prolongé. Dans ce ças, le limiteur réduit le niveau du signal audio (jusqu'à 10 dB) de façon à minimiser l'écrêtement. Lorsque l'écrêtement cesse, le limiteur se retire et cesse la réduction de gain.
