matically mute all HRM-16 sends except the  
channel D stereo and talkback outputs. This  
unique feature allows each musician to hear a  
rough or final mix and send soloed tracks from  
the mix console. This eliminates the need for  
musicians to relocate to the control room or  
manually change their HRM-16 level settings.  
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  
Note: Both the solo function on the HDS-16 and  
the talkback system on the HRM-16 can be acti-  
vated manually using their front panel controls or  
by optional remote switches.  
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 connector types are used for  
the same channel, the TT connector will be ac-

16’s. Talkback is always available from the mix  
console and the level can be adjusted with the  
HRM-16’s TALKBACK VOLUME control.  
There are two talkback modes designed for  
live and studio situations:  
LIVE/STAGE MODE (DEFAULT)  
This mode establishes communication from the  
HDS-16 to all HRM-16’s but not between them.  
Each HRM-16 user must depress their TALK  
button or switch to speak with the HDS-16 but  
can always receive from it. The HRM-16 users  
will not hear other HRM-16 users or their own  
voice. This is useful for live situations where  
a single HRM-16 user’s communication with  
the mix engineer does not require interaction  
between musicians. Live/Stage was selected  
as the default mode to eliminate feedback from  
adjacent stage monitors.  
STUDIO MODE  
This mode establishes communication among  
all HRM-16’s and the HDS-16 much like an  
intercom system. Any HRM-16 user with their  
TALK button depressed can speak to all HRM-  
16’s and the HDS-16. Each person will also  
hear their own voice.This mode is useful to  
enable discussion between the musicians and  
mix engineer between takes.

This feature allows musicians at the HRM-16s  
to hear rough and final mixes or soloed tracks  
from the recording console without exiting to

about cable losses beyond 100 ft.  
Push the AC-power switch up to the ON posi-

REAR PANEL  
The GROUND lift switch has two positions:  
The HDS-16 rear panel has six, 50-pin, Cen-  
tronics output connectors for the HRM-16s,  
AC-power, and ground switches (Figure 5).  
While male-to-male Centronics cables are  
available from computer retailers, Furman  
manufactures superior quality cables with  
twisted pair construction to optimize sound  
quality and reject cross-talk interference. We  
highly recommend using the 25 twisted pair,  
shielded, 25-ft cable supplied with each HRM-  
16. Contact Furman for other cable lengths and  
linking adapters.  
LIFT: Signal ground is separate from chassis  
ground. Earth ground (AC line cord) is con-  
nected to the chassis only.  
GROUNDED: Signal ground is connected to  
chassis ground; use this setting unless there is  
hum or noise present.  
Note: Be sure all units are turned off before con-  
necting an HDS-16 to one or more HRM-16’s.

TALKBACK  
The HRM-16s receive their input signals and  
power supply entirely through the Centronics  
cable from the HDS-16. Eight mono and four  
stereo channels can be mixed and monitored  
with headphones or sent to a monitor system.  
The eight mono channels may be routed to  
the EFFECTS SEND output on the rear panel.  
The effected signal is returned to the HRM-16  
through the stereo effect returns on the rear  
panel and blended into the mix with the EF-  
FECTS RETURN level control. The HRM-16  
can be easily mounted on a microphone stand  
with the thumb screws and clip provided, or  
placed on a table or shelf.  
Press the TALK button and speak in the direc-  
tion of the built-in microphone above the button  
(three small holes in the shape of a triangle).  
The microphone will pick up voices from up to  
six ft away so you do not need to speak directly  
into it. Use the TALKBACK VOLUME control to  
alter the level of incoming talkback information.  
See page 4 for a complete description of the  
talkback functions.  
REAR PANEL  
The HDS-16/HRM-16 system can be connect-  
ed in parallel or series without compromising  
sound quality or power as long as no more  
than four HRM-16s are connected in series  
from a single HDS-16 output.  
TOP PANEL  
The top panel provides:  
Level controls for four STEREO SOURCES;  
Parallel: Each HRM-16 is connected directly to  
the HDS-16 in a star configuration.  
EFFECTS SEND, L/R pan, and level controls  
for each of eight mono channels;  
Series: One HRM-16 is connected directly to  
the HDS-16 with additional HRM-16’s con-  
nected together in a daisy chain.  
MASTER volume control;  
HI and LO shelving EQ controls with 12 dB  
boost and cut;  
Two, 50-pin, Centronics connectors are located  
on the right of the HRM-16’s rear panel:

HRM-16  
The headphone driver and power supply regu-  
lators are protected against over-temperature  
and current overloads. The regulated power  
delivered from the HDS-16 to the HRM-16 is  
protected against over-current by PolySwitch  
resettable fuses inside each HRM-16. These  
fuses prevent a defective HRM-16 from shut-  
ting down the HDS-16 or attached HRM-16s.  
Both devices reset automatically after clearing  
the fault and removing power to the circuit.  
TALKBACK SWITCH REMOTE: Plug a mo-  
mentary switch into this jack to use instead of  
(or in addition to) the TALK button.  
OUTPUT TO ADDITIONAL  
HRM-16’S  
This connector carries the same signal sent  
to the INPUT FROM HDS-16 connector. Con-  
nect this output to another HRM-16’s INPUT  
FROM HDS-16 connector to achieve a series  
connection. An output that simply replicates the  
input is often called input through because the  
signal is sent out before being processed in  
the device. As a result, the HRM-16’s top panel  
controls do not affect the OUTPUT TO ADDI-  
TIONAL HRM-16’s signal.  
HDS-16  
The regulated power delivered from the HDS-  
16 to the HRM-16 is protected against shorted  
cables by an over-current crowbar circuit. The  
affected power supply turns off in response  
to an over-current condition. Restore normal  
operation by removing the defective cable or  
HRM-16 and turn off the power to the HDS-16  
for at least 30 seconds.

The AC-line fuse is a 1-Amp Slo-Blo. Replace  
it only with a fuse of the same type and rating.
