The B-D2020 is a compact, lightweight Dante/AES67 beltpack for commentators, presenters and pitchside reporters. It provides a programme microphone output that can be diverted silently to two independent talkback outputs, together with a combined feed. Its two listening volume controls can each receive mono or stereo audio. The OLED displays microphone level and on-air or talkback status, and provides access to talk-key modes, microphone gain, limiter, 48 V phantom power and sidetone. Microphone gain is adjustable from 0 to +66 dB in 1 dB steps. The talk keys can operate momentarily, latch, be disabled or serve as cough/mute keys. Connections include a three-pin XLR microphone input, a 6.35 mm TRS headphone output and networking through RJ45 or locking etherCON. The unit can receive up to four audio channels from a maximum of two network devices. Power is supplied by PoE or a 12 V DC adaptor. Dimensions are 115 x 83 x 45 mm; weight is 0.34 kg.
