AUDIO DISTRIBUTION
SYSTEM
The HDS-16, a 2-U rack-mountable device
normally located near the main mixing console,
provides the power and signal conditioning
for a maximum of eight HRM-16’s. Individual
channel sends from the console connect to the
HDS-16 inputs.
FRONT PANEL
The front panel serves as the patch bay for all
input connections: eight mono and four stereo
¼-inch and TT input connectors. All connec-
tors are balanced and use the Tip/Ring/Sleeve
(TRS) wiring convention. Both ¼-inch and TT
connectors can be used but not for the same
channel. If both con nec tor types are used for
the same channel, the TT connector will be ac-

Figure 2 shows the TALKBACK connectors at
the far left of the front panel. Connect the mix
con sole’s line-level, talkback-microphone out-
put or cue send to the HDS-16’s ¼-inch INPUT
jack. This signal is distributed to the HRM-16s
on the Centronics cable along with the other
channels. Use the RETURN FROM HRM-16
connector to monitor talkback from the HRM-
