Shure DRS-10 User manual

GENERAL
The Shure DRS-10 is a digital switching system that
provides remote scene selection when connected to the
DFR11EQ version 5. The DRS-10 consists of a hardware
adapter, a 10-position switch assembly, and a mounting kit.
The DRS-10 provides remote access to all ten scenes that
can be stored onboard the DFR11EQ. In addition, the
DRS-10 can be customized for use in a three position switch
configuration (not included).
IMPORTANT OPERATIONAL INFORMATION
The DRS-10 works only with the DFR11EQ version 5.
The DFR11EQ must be in global scene mode when a switch
assembly is used (refer to the DFR11EQ User Guide). No
switch assembly can be used to control scene selection si-
multaneously with the software. The DFR11EQ should be
on with the DRS-10 plugged in to execute a scene selection.
Multiple switches can be used to control a DFR11EQ
when wired in parallel (contact Shure’s Applications Depart-
ment for details). When using multiple devices for scene
control, the most recent scene selected using any device
overrides any previous selection. However, if the power is
cycled (turned off, then on) the DFR11EQ may not default
to the correct scene.
CONNECTING THE HARDWARE ADAPTER TO THE
10-POSITION SWITCH ASSEMBLY
To connect the hardware adapter to the supplied switch
assembly (Figure 1):
1. Determine the distance needed between the mounting
area and the DFR11EQ unit. Trim cable to size.
NOTE: Cable not supplied. A two-conductor, unshielded
cable, such as a Belden 8442, is recommended. The total
resistance of the cable run must be less than 100 ohms.
2. Connect terminal 1 of the switch assembly to terminal
C (common) on the hardware adapter using cable.
3. Connect terminal 2 of the switch assembly to terminal
S (switch) on the hardware adapter.

USING CUSTOM SWITCHES
The DRS-10 hardware adapter can be used with a custom-
built switch. Refer to Table 1 for the resistor values needed
in the switch to access the desired scenes.

83.3-4.1 kΩ
91.9-2.5 kΩ
10 0.63-1.1 kΩ
CUSTOMIZING THE DRS-10 FOR USE IN A
3-POSITION SWITCH CONFIGURATION
To connect the hardware adapter to a 3-position switch
(not supplied):
1. Determine the distance needed between the mounting
area and the DFR11EQ unit. Trim cable to size.
NOTE: Cable not supplied. A four-conductor, un-
shielded cable, such as a Belden 9744, is recom-
mended. The total resistance of the cable run must be
less than 100 ohms.
2. Connect a 3-position switch to the hardware adapter as
shown in Figure 2. The switch should be wired to pro-
vide a separate contact between the C (common) termi-
nal and each of the three numbered terminals.
NOTE: Do not use a switch configuration which allows
more than one contact-closure at a time.

CONNECTING THE HARDWARE ADAPTER
TO THE DFR11EQ
Once the switch assembly and hardware adapter are
connected, plug the hardware adapter of the DRS-10 into
the RS232 port of the DFR11EQ (see Figure 3).

MOUNTING THE DRS-10 SWITCH ASSEMBLY
TO A WALL
The switching assembly of the DRS-10 may be
mounted using the supplied mounting kit (Figure 4):
1. Mount a standard electrical box into the wall.
2. Place the position ring onto the switch assembly, fitting
the tab of the ring into the desired numbered groove on
the switch assembly.
NOTE: The switch assembly of the DRS-10 can be cus-
tomized to select up to ten scenes. The location of the
position ring determines how many scenes the switch is
able to access.
3. Peel the plastic sheath from the affixed labels on the wall
plate and hardware adapter. A second 10-position label
is provided for use on custom wall plates.
4. Insert the switch assembly post through the lock washer
and wall plate and attach with the supplied washer and
nut, being careful not to over-tighten the nut.
5. Press the supplied knob onto the switch assembly post.
6. Secure the wire cable to the switch assembly using the
two screw terminals on the back of the assembly, as
previously described in Figure 1.
7. Mount the assembly to the electrical box in the wall.
