Bosch - PLE-SDT Tuner

This is a professional Bosch tuner from the PLE-SDT series, designed for public address and audio distribution systems, presented in a rack-mmountable equipment format. The unit features a robust construction with a black metal chassis, clearly identifying the front and rear panels, and a functional design characteristic of professional audio equipment.

On the front, the Bosch brand appears in the center, accompanied by the label “TUNER.” The panel includes an information display, a numeric keypad for station or program selection, tuning and programming buttons, and status indicators. The equipment also provides connections and controls associated with playback and source selection, including USB and SD card support, enabling the use of different audio sources.

At the rear, there is an antenna input, a USB port, and several individual output level controls labeled “TUNER,” “COMBINED,” and “USB/SD.” There are also multiple RCA audio outputs, organized by channel and source, namely TUNER, COMBINED, and USB/SD. This configuration allows the unit to be integrated into sound distribution systems and connected to other audio equipment.

The identification plate visible in the photographs confirms the Bosch brand and the PLE-SDT series designation, indicating equipment intended for professional audio applications. The label also bears the relevant compliance markings and electrical information, including compatibility with 110–120 V and 220–240 V power supplies at 50/60 Hz, a feature the buyer should consider according to the configuration used.

The equipment shows signs of use and cosmetic wear appropriate to its age and prior use, including some markings, superficial scratches, and signs of handling visible on the chassis and front panel. The controls, buttons, connections, and engravings remain present, allowing clear identification of their different functions. The photographs show the device in generally good exterior condition, though the buyer is advised to treat the images as part of the description of its aesthetic state.

Given its features, this is a particularly interesting unit for collectors of professional audio equipment, sound technicians, installers of sound systems, churches, auditoria, commercial spaces, institutional facilities, or sound distribution systems that use Bosch PLE-series equipment. The device stands out for its professional build, the variety of inputs and outputs, and the ability to use different audio sources via the tuner, USB, and SD.
