RDL DB-PA3 overview

  • 1Description

The wall-mounted, black DB-PA3 3.5 Watt Audio Amplifier from RDL comes with two line inputs and an amplified output to drive a 4 or 8-ohms speaker. It features a balanced line level input that may be connected to unbalanced. The gain range will accommodate standard unbalanced levels as well as professional balanced levels. In addition, it also features a stereo mini-jack input on the front panel, which is designed to receive standard -10 dBV consumer level signals from sources such as, a computer or personal media player. The left and right audio signals received on the mini-jack are summed to mono and amplified. When a source is connected, the rear-panel input is switched off. The amplified output level is controlled by a front-panel volume control.

A recessed slide switch on the side of the chassis is set during installation, which determines the sensitivity of the balanced rear-panel input. Amplification is provided by a high-efficiency Class D power stage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat for all levels of expected voice or music modulation. It is designed so that it can be mounted in a wall box. The front panel of the amplifier does not include any illuminated indicators, which makes it ideally suited to installation in dark rooms or areas. Its wiring is connected through a rear-panel detachable terminal block. The module operation is from a 24 VDC ground-referenced power supply.
