ProTone 7005

4-channel power amplifier with controlled power supply

ProTone 7005 is a class D 4-channel power amplifier with controlled power supply. This controlled power source provides power stabilization of voltage distribution bus of the whole device even during wide supply voltage fluctuation.

Design and ergonomics of «ProTone 7005» are well thought-out: a mode indicating element is located on the front board allowing to control the working mode of the device. There are input and output connectors such as 3-pin XLR, balanced connector, speakON 8, speakON4 on the back board. VPL peak limiter could be defined by DIP-switcher to protect acoustic system.

Efficient thermal management of the power amplifier is assured by three electronically controlled coolers; the rotation speed of coolers is being adjusted in accordance with the internal temperature inside the power amplifier’s housing. ProTone output stages are designed to perform optimally on 2.66 Ohm load in low-frequency range.
