Employing a modular amplifier bank approach to output channels; AT3300 amps are designed for efficient and powerful performance up to 4 channels on a compact 13.5” depth chassis for models AT3302, AT3303 and AT3304. In these models, up to 4 channels may be located at one side of the amplifier’s internal chassis for cooling efficiency. When increased channel counts are required such as 5 to 8 channels, a second toroidal transformer is incorporated to power the additional modular amplifier bank for channels 5-8 as in models AT3305, AT3306, AT3307 and AT3308 on a 16.5” depth chassis.
With this efficient internal mechanical design, a cooling tower for all channels is achieved. A CPU and temperature controlled 140mm (5.5”) computer fan positioned at each amplifier bank ensures continuous and quiet airflow cooling.
