The TR-800-A4R from Bosch is a 2-audio channel UHF frequency-agile wireless beltpack for use with the BTR-800. The TR-800-A4R is a metal cast magnesium case, an LCD-based user interface, stage announce activation, WTA (Wireless Talk Around), enhanced ClearScan, detachable antennas and an auto-sensing headset connector that automatically switches between the electret and dynamic headset mics.
Turns the beltpack power on and controls headset volume.
When pressed, the user’s audio is disconnected from the wired intercom, auxiliary input/output and the base station’s local headset. Other beltpack users, on that audio channel, can hear the user as normal.
When pressed, the user’s audio is routed to the SA (Stage Announce) connector on the back of the base station. The user also loses their sidetone as an indication that stage announce is activated. The other wireless beltpacks and wired users do not hear the user’s audio. The button is non-latching and activates the nearby red LED.
Allows user to select either audio channel A or B.
Light flashes once when the unit is turned on if the battery is good. If the light stays on, the battery is low. If the light does not flash, the battery is dead. A normal microphone gain setting causes the LED to flash at the beginning of most words at normal speech levels. If the gain is too high, the LED is red during the complete word at normal speech levels.
LED is on when the talk button, SA or WTA is active.
The TALK LED, turns red when enabled. A quick press and release latch the talk function unless latching has been disabled. Holding the button for over half a second causes the audio path to be enabled only for as long as the button is held. If the talk function is latched on, pressing the talk button again turns it off.
