DESCRIPTION
The Furman
HDS-6 / HR-6 Audio Distribution System offers a great-sounding,
cost effective and flexible way to provide custom mixes for
up to sixteen people in recording and live sound environments.
The combination of unique functions add unprecedented functionality
and convenience to any multiple-user audio application.
The system
consists of two components: the rackmount HDS-6 Audio Distribution
System, and one or more HR-6 remote mixers (please note that
the HR-6 remote mixers are sold separately). Linking the distribution
unit and remote mixers is as easy as plugging in cables --
multiple HR-6's are simply daisy-chained together. A pair
of 25 foot linking cables is included with each HR-6, and
other lengths are easily obtained at your local computer store
or through mail order. For applications where daisy-chaining
is not practical, a twelve port or larger ethernet patch panel
can be wired to allow multiple HR-6 units to connect from
a central location. Up to eight HR-6 remote mixers can be
linked to an HDS-6, and two pairs of headphones may be plugged
into each HR-6.
The HDS-6
rackmount distribution system connects to the mixer/console
to provide interface and power supplies to drive a group of
HR-6 remote mixers. Trimpots are provided on the HDS-6's front
panel to match the console output levels to the HDS-6's inputs.
The HDS-6
is ideal as a low distortion headphone driver for the most
critical listening situations. In addition to providing high
current differential buffered signals, it also provides power
and ground to the HR-6 remote mixers.
The HR-6
is a compact six-channel, five-pot remote mixer that clamps
to any mic stand. When used with the HDS-6, the HR-6 allows
musicians to customize their own headphone or monitor mix,
and the engineer doesn't have to touch the board.
The HR-6
provides four mono pots and one stereo pot. The four mono
pots allow each user to create a custom mix of four console
channels or busses. The stereo pot will most often be used
for a main control room mix, or for a stereo effects return.
The HR-6
also provides a "Submixes Included/Excluded" button, which
mutes the four mono pots, allowing only the stereo source
to be heard, without having to alter the HR-6's four monaural
settings.
The HDS-6
/ HR-6 Audio Distribution System and HR-6 Remote Mixer are
designed for high-end audio applications, yet are affordable
enough for home studios and general live sound applications.
Architects and Engineers Specifications
The Audio
Distribution System shall mount in a standard 19" rack, and
shall occupy no more than one rack unit (1 3/4") of rack space.
It shall provide signal and power sufficient to drive a chain
of up to eight remote headphone mixing stations, each of which
shall provide the capability to mix four monaural sources
and one stereo source. Connections to the user's mixing console
shall be via either TRS balanced or unbalanced 1/4" jacks.
Trimpots shall be provided to match console output levels,
including -10 and +4 dBu. LEDs shall be provided to indicate
overload for each channel, link cables reversed, and power
on.The unit shall be internally fused, and shall have a Ground
Lift switch capable of isolating the signal ground from the
chassis. There shall also be an on/off power switch.
The remote
mixer's power output shall be 400 mW at 32 ohms (200 mW at
600 ohms, 500 mW at 100 ohms) from 20 Hz to 20 KHz. Distortion
shall be 0.008% THD or less at full rated power at 1KHz, and
not more than .05% from 20 Hz to 20 KHz. The noise level shall
be at least 96 dB below full rated output at 32 ohms load
with 0 dB in.Each mixing station shall accommodate two sets
of headphones.
Each remote
mixer shall provide four mono pots, one stereo pot and a switch
to mute the mono pots while leaving the stereo pot active.
Provision shall be made for linking multiple remote mixers
using two standard 10Base-T ethernet cables, which shall connect
in daisy-chain fashion. Additionally, simple paralleling of
HDS-6 outputs can be accomplished using appropriate ethernet
patch panels to facilitate multi-room installations where
daisy-chaining is not practical. The remote mixers shall be
provided with removable clamps that allow easy attachment
to mic stands.
The system
shall be the Furman HDS-6 Audio Distribution System and the
Furman HR-6 Remote Mixer.
