Extra Information RB-DHD6 - Digital Headphone Amplifier, Six Outputs
USED BUT IN NEAR PERFECT CONDITION
The RB-DHD6 digital 6 way headphone distribution amplifier is a 1U rack-
mount which receives a digital input signal, as either AES/EBU or S/PDIF and
converts it to 6 individually buffered, jack-plug, headphone outputs, each with
their own volume control.
Useful for connection to digital mixing desks, digital routers and matrices, the RB-DHD6
connects directly to an AES/EBU or S/PDIF output to provide the highest quality audio
directly to the headphones. The input connectors consist of a single balanced XLR-3 for the
AES/EBU input and a single unbalanced phono connector for the S/PDIF input.
A button located on the rear panel is used to select either the AES/EBU, or S/PDIF, input and
de-emphasis on the output can be controlled via dipswitch. If de-emphasis is selected, the
RB-DHD6 will decode 50/15μs emphasis when indicated by certain channel status bits in the
incoming digital audio data.
When operating, the front panel power LED flashes red and amber whenever the unit is not
synchronised to the incoming digital signal.
Sync & Power Indicator
The LED on the front panel is normally red to indicate that power is present on the unit.
However, it also has a secondary role to indicate the status of the digital inputs
Flashing between red and amber – indicates a loss of a valid digital input signal.
Headphone Outputs
The headphone outputs on the front panel consist of six ¼” stereo jack sockets, designed to
drive 150 mW into 32Ω to 600Ω professional headphones.
Volume Control
The headphone outputs each have their own volume control and have a maximum output
level of +12dBu. |
