1 Welcome
Thank you for purchasing the Crown
R.S.V.P.
(Remote Switching Voltage
Provider) accessory module, de-
signed for use with Crown’s CT-10
series amplifiers. The
R.S.V.P.
takes
advantage of Crown’s CT-10 series’
soft-start feature, eliminating the
need for expensive sequencing
equipment or complicated startup
routines.
Using Crown’s
R.S.V.P.
module, you
can control the power-up/power-
down function of your CT-10 series
amplifier from across the room—or
across the stadium. Each
R.S.V.P.
unit controls 21 amplifier remote
jacks. That’s enough to control a 6-
foot (1.83 meter) rack of amplifiers
and still have one jack left over to
chaintoanother
R.S.V.P.
Unitsarein-
dividually powered, allowing you to
daisy-chain any number of
R.S.V.P.
s
for remote control of an unlimited
number of amplifiers.
Power-up/power-down can be con-
trolled using an auxiliary device
(such as an
IQ System
) via the aux
port, or through the use of a pair of
momentary switches. Remote mo-
mentary switches can be connected
inparallel,soyour amps can be con-
trolled from various locations: front of
house, backstage, lighting booth,
and so on. With a maximum switch-
ingdistanceofupto2000feet(609.6
meters) per unit, the
R.S.V.P.
can
provide on/off capabilities any-
where—oreverywhere—youneed it.

trol 21 separate CT-10 series amplifi-
ers, or the
R.S.V.P.
can be
daisy-chained to other

3 Installation
This section will give the necessary
information for installing the
R.S.V.P.
into your equipment rack. It will also
provide ways to incorporate the
R.S.V.P.
into your system. Please
read this section thoroughly, as the
R.S.V.P.
has special cooling and
mounting requirements.
3.1 Cooling
Make sure that the vent holes of
the
R.S.V.P.
are NOT obstructed.
When mounting the unit in the back
of your rack, avoid blocking air flow
to all of your rack-mounted equip-
ment
.
3.2 Mounting
The
R.S.V.P.
is designed to be
mounted in the REAR of a standard
19-inch (48.3-cm) equipment rack.
Placing it in the back of the rack pro-
vides a more tamper-resistant loca-
tion and allows for easier access to
equipment.Fourkeyholes on the unit
can accomodate up to a #10 screw.
For a more secure installation, four
0.2- inch (0.5-cm) holes are also
available.
.
3.3 Wiring for Amplifiers
Convenient RJ-11 connectors link
the
R.S.V.P.
to the remote CT-10 se-
ries amplifiers. Please note that the
RJ-11jacksare polarity sensitive. Pin
4 must be grounded, and Pin 3 must
be supplied with a positive voltage
pull up (positive with respect to
ground). Refer to Figure 3.1 for RJ
jack pin assignments.* The maxi-
mum signal that can be exposed to
theRJ-11jacksis35VDCor25VAC.
(RJ-11connectors areavailablefrom
the Crown Parts Department.)
Figure 3.2 shows one possible sys-
tem configuration using the
R.S.V.P.
andarackofCT-10seriesamplifiers.
Runs of less than 30 feet (9.15
meters) between the
R.S.V.P.
and
the amplifiers are required for the
R.S.V.P.
to function properly. Up to
21 CT-10 series amplifiers can be
controlled from a single
R.S.V.P.
However, daisy- chaining together
units, as shown in Figure 3.3, can
provide for an unlimited number of
amplifiers in a system.
* The mating connector for the
R.S.V.P.
RJ-11 jack contains 4 contact pins in a 6-slot
case, as shown. For additional information please contact your local dealer or
Crown Technical Support.

3.4 Daisy-Chaining Multiple
R.S.V.P.
Units Together
You’ll need standard cable with RJ-
11 connectors to daisy-chain mul-
tiple
R.S.V.P.
units together. (Refer to
Section 3.3 for information on the RJ-
11 connectors.) To slave
R.S.V.P.
units, connect one end of the cable
from one of the “To Amplifier Re-
mote” ports on the
R.S.V.P.
unit
which will be configured as the mas-
terunit.*Connecttheotherendofthe
cable to the “Slave/Aux In” port on
the remote unit. This run can be as
long as 2000 feet (609.6 meters), al-
lowing control of several systems
from one location.
See Figure 3.3 for a sample system
configuration when daisy-chaining
multiple
R.S.V.P.
s. Figure 3.4 shows
several units in a bus configuration,
while Figure 3.5 shows how to set up
a star configuration using several
R.S.V.P.
s.
* Note: The unit selected to be master will be wired to receive the power-up/power-
down signal from momentary switches via the On/Com/Off connectors, or from an
attached IQ System via the Slave/Aux In port.
3.5 Wiring for Remote
Control via the “Slave/Aux
In”Port
In addition to providing for daisy-
chaining of
R.S.V.P.
units, the “Slave/
Aux In” port also allows for control of
yoursystem to be providedusing an
IQ System
via the IQ Aux port (see
Figures 3.6 and 3.7). In fact, the sys-
tem can be controlled by a variety of
auxiliaryunitsaslongastheyprovide
10-35 VDC or 10-25 VAC output.
Simply connect one end of the cable
to an IQ Aux Out port (or other auxil-
iary equipment of your choice). Be
sure to refer to your equipment’s ref-
erence manual for proper wiring in-
structions. Then connect the other
endofthecableto the“Slave/AuxIn”
port on the
R.S.V.P.
unit. Runs of less
than 2000 feet (609.6 meters) are
recommended to ensure proper
functioning of the
R.S.V.P.
unit.
