Coach AudioAmplifier 12.24

Description

The Coach AudioAmplifier 12.24 has an output power of 2 x 20 watts. The amplifier has been designed for use with Coach MultiMedia systems from Bosch. The Coach AudioAmplifier 12.24 provides low-level inputs (ISO D1, D2, D5) and, in addition, high-level inputs (ISO D7-D10) that can be used, for instance, for connection to the loudspeaker outputs of the radio. Levels can be adjusted with the Audio Gain control. When the arrows are in the vertical position, this means that the factory preset gain settings are set. The rotation directions for increasing or decreasing the gain are indicated by the + and – symbols. The amplifier is switched on and off via the radio (ISO A5 or D6). To make microphone announcements, two dynamic microphones can be hooked up. For microphone announcements, the Coach AudioAmplifier 12.24 is switched to microphone mode. Microphone A has priority over microphone B. The volume level is set using the corresponding input control for microphone A or B on the amplifier. Optionally, it is possible to connect a level control for both microphones (ISO D3, D4). Microphone announcements can also be made when the radio is turned off. The amp needs sufficient ventilation. Therefore, be sure to mount it in a well-ventilated and dry place.
