* Tinned fiberglass printed circuit boards to withstand higher currents and increase durability.

* Aluminum front panel and steel chassis.

* Electronic protection circuit against short circuit or output overload.

* Advanced design and internal layout developed for easy circuit maintenance.

* Circuit protection against overheating with thermo mechanical sensor.

** Forced cooling made by two turbo fans (one for each channel) and heat sinks with large dissipation area.

* Automatic DC level control at the amplifier output. (maximum 5mV).

* DC protection circuit at the output, with high current relays.

* Super sized power supply with toroidal transformer.

* Electronically balanced inputs with XLR connectors.

Class AB circuit, suitable for working in any frequency range.

Operates only with 240V network. (RS512 - Bi-Volt).

* Subsonic and ultrasonic frequency filters.

BARGRAFF type VU for easy power monitoring.
