Sonifex RB-TGHD Multi-Channel High-Definition Tone Generator

The Sonifex RB-TGHD Multi-Channel High-Definition Tone Generator is an 8-channel audio tone generator that provides line identification for multi-channel audio systems, including 5.1 and 7.1 surround sound typically used in high-definition television broadcasts. By using a range of widely accepted industry standard tone sequences such as the EBU R49, GLITS, and BLITS tones, channel identification and associated levels can be determined easily. The RB-TGHD caters for 2, 4, 6, and 8 channel configurations and all the available audio tone sequences for each channel configuration can be cycled through automatically or selected manually, and a loop mode allows patterns of tones to be repeated. A set of 8 LEDs on the front panel indicate which channel is currently outputting audio with the LEDs numbered as both 1-8 and as L, R, C, LFE, LS, RS, LR, and RR.
