2734 Power Amplifier

2734-B Power Amplifier

The 2734 is a compact class D power amplifier, intended for acoustical measurements in the field or laboratory. All controls and connectors are placed on the front panel, enabling you to set up the 2734 very quickly, and to operate it in horizontal or vertical position. The 2734 is built into a robust flight case making it safe and easy to carry along.

There are two variants of the 2734. The 2734-A is the basic version, whereas the 2734-B includes a wireless audio receiver which can be used to send a stimulus to the amplifier. Both models can be operated remotely using the optional UA-1476 wireless remote control.
