Description
The black DB-TPA1A 3.5W Audio Power Amplifier from RDL is a 2-pair audio amplifier compatible with the RDL Format A twisted pair products. Each D-TPA1A receives stereo audio and 24VDC power through a rear-panel RJ-45 jack. The left and right audio signals received on pairs B and C of the twisted pair cable are summed to mono and amplified. The amplified output level is set by an internal VCA, which is controlled by a front-panel volume control. The VCA attenuator provides years of scratch-free gain adjustment.
The DB-TPA1A circuits are all designed for low power consumption. 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. When the user reduces the audio level to minimum, the class D output stage is switched off. This Sleep mode remains active until the user turns up the output level.
The output drives either a 4 or 8Ω speaker. The speaker cable connects to the module using a detachable terminal block. The front panel does not include any illuminated indicators, thereby making the DB-TPA1A Amplifier suitable for installation in dark rooms or areas. Installation is simple and quick, requiring only the connection of the speaker leads and the twisted pair RJ-45.
The DB-TPA1A Amplifier may be fed and powered from any RDL Format-A sender, and is useful in hospitality installations fed from a sender connected to a TV monitor (for example: FP-TPS4A Audio Sender from TV with fixed audio output level).
Use the DB-TPA1A Audio Power Amplifier wherever a single speaker, user-adjustable, wall-mounted amplifier is needed. It can be combined with other RDL Format-A products for a cost-effective, high-performance audio system.
