* 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.
