SONIFEX TELEPHONE BALANCE UNITS

HY-03 Analogue telephone hybrid

DHY-04 DSP based telephone hybrid

DHY-04 series is the ‘redesign of DHY-03’ telephone hybrid units with the addition of Ethernet connectivity. Ethernet connectivity enables the engineer to configure and control the unit via a remote web browser. The addition of AES/EBU digital inputs, along with analogue audio inputs give for better quality and performance, whilst the addition of speed dial buttons, located on the front panel, aids ergonomic usage.

Other features of the DHY-04 include dial tone recognition (DTMF), which allows a remote caller to dial in using a pre-programmed password and automatically connect to on-air status. Like the DHY-03, DHY-04 offers full adaptive echo cancellation to 127msec default is set to 24msec, however DSP increases the unwanted sideband rejection to 70dB (measured using tone, ref. 0dBu peak output) as opposed to 72dB of the DHY-03.

Dimensions (WxDxH): 218 x 45 x 175mm, DHY-04; 483 x 45 x 175mm, DHY-04S or T

Versions available:

DHY-04 Single unit, freestanding
DHY-04S Single unit, rackmounting
DHY-04T Twin unit, rackmounting
