Product description The stainless steel 3.5W Audio Power and Headphone Amplifier from RDL features one line input, an amplified output to drive a 4 or 8Ω speaker and a separate headphone amplifier. It features a balanced line level input that may be connected unbalanced. The gain range accommodates standard unbalanced levels as well as professional balanced levels. Its amplified output levels are controlled by a front-panel volume control. This amplifier features a mini-jack headphone output on the front panel. When a headset is plugged in, the power amplifier may be switched off. The two recessed slide switches located on the top of the rear enclosure are set prior to mounting the module. One switch is provided for setting the input sensitivity. The mute switch determines whether the power amplifier operates when headphones are plugged in. Amplification for the speaker output 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. Furthermore, the amplifier is designed to be mounted in a wall box. Its front panel does not include any illuminated indicators, making it suitable for installation in dark rooms or areas. The wiring is connected through a rear-panel detachable terminal block and module operation is from a 24 VDC ground-referenced power supply. - Wall-mounted amplifier with two outputs
