VCA-MC Series Amplifier Accessories
Operation Manual
1 Welcome
The VCA-MC (VCA multichannel module) is an optional accessory module for the CTs
4200 or CTs 8200 power amplifier. The module provides independent remote level control
for each channel. VCA-MC4A (Figure 1.1) is the VCA module for the CTs 4200. VCA-
MC8 (Figure 1.2) is the VCA module for the CTs 8200.
Four-pin removable Phoenix-style barrier connectors provide the +10 VDC control voltage,
ground, and control inputs for two amplifier channels. Thus, the 4-channel CTs 4200 uses
two connectors; the 8-channel CTs 8200 uses four connectors. The control inputs are
labeled VCA1 (for channel 1), VCA2 (for channel 2), and so on.
VCA-MC modules can be controlled in one of two ways:
• Optional Crown 1-VCAP or 4-VCAP wall-mount level controls
• An external control voltage of 0 to 10 VDC
1-VCAP: See Figure 1.3. Used in conjunction with a VCA-MC module, this is a single-
gang panel with one potentiometer that provides remote volume control for one or more
CTs amplifier channels. The potentiometer on the panel is wired directly to the VCA con-
nectors on the VCA-MC.
4-VCAP: See Figure 1.4. This is a two-gang panel with four potentiometers that provide
remote volume control for four or more CTs amplifier channels. The potentiometers on the
panel are wired directly to the VCA connectors on the VCA-MC.

1.1 VCA Module Features
• Provides independent remote level control for each channel of a Crown CTs 4200 or CTs
8200 power amplifier.
• Four-pin removable Phoenix-style barrier connectors provide the +10 VDC control
voltage, ground, and control inputs for two amplifier channels.
• Can be controlled by Crown VCAP wall-mount level controls or external DC source
(0 to 10 VDC).
• Any number of control inputs can be electronically tied together to control several chan-
nels from one VCAP or 10VDC voltage source.
• 0 dB attenuation default. If nothing is connected to a control input, the VCA module
defaults to unity gain.
• VCA gain element is in series with amplifier attenuator, allowing the maximum gain of
the system to be set at the amplifier.
1.2 1-VCAP Level Control Features
• Provides remote volume control for one or more CTs amplifier channels.
1.3 4-VCAP Level Control Features
• Provides remote volume control for four or more CTs amplifier channels.

Operation Manual
3 Setup
It is important that you read and understand Section 4 “Operation” and Sec-
tion 5 “Theory of Operation” before completing the setup of the system. Seri-
ous damage may result to the loudspeakers if VCA operation is not well
understood.
The VCA-MC4A and VCA-MC8 can be controlled either by Crown VCAP wall-mount level
controls, by your own potentiometer, or by an external variable-voltage source (0-10 VDC).
3.1 Wiring to the 1-VCAP or 4-VCAP Wall-Mount Control
1. Install a single-gang junction box for the 1-VCAP or a double-gang junction box for the
4-VCAP. Run a cable between the junction box and the power amplifier, allowing some
slack on both ends. No cable is provided. CAT-5 cable will work fine, but Crown recom-
mends using standard twisted-pair shielded microphone cable.
2. See Figure 3.1. In this example, the twisted-pair HOT led is white; the twisted-pair COLD
lead is black. On the VCAP circuit board, pull out and turn over the removable barrier-
strip plug to expose the screws. Then connect the cable leads to the barrier-strip plug
from left to right as follows: COLD lead, HOT lead, Shield. The facing side of the VCAP
circuit board is labeled accordingly.
3. Turn over the barrier-strip plug and insert it into the socket in the VCAP level control.
4. Trap the cable under a wire tie inserted into the holes in the board as shown. Wire-tie
holes are also provided on 4-VCAP panels.
Figure 3.1 Wiring the
VCAP Level Control to the
VCA-MC Module

VCA-MC Series Amplifier Accessories
page 8 Operation Manual
5. Align a supplied barrier plug with the corresponding pins in the VCA-MC4A or
VCA-MC8 module. Attach the cable to the plug as follows:
Connect twisted-pair HOT lead to the VCA channel terminal(s) you want to control.
Connect twisted-pair COLD lead to the +10V terminal.
Connect cable shield to the GND terminal.
The pin labeled GND on the VCA module is connected directly to the internal ground of the
amplifier. NOTE: Do not connect this pin to any ground or extend it for any other
purpose.
In the VCAP wall-mount panel, do not connect the ground pin to the VCAP metal panel or
its junction box.
3.2 Wiring Your Own Potentiometer
You may use your own linear-taper potentiometer to control the VCA-MC module. We rec-
ommend using a 5 k ohm potentiometer; however, values up to 100 k ohms are acceptable.
A potentiometer near 100 k ohms may require an RFI bypass capacitor.
Wire the potentiometer as shown in Figure 3.2. Connect one end-terminal of the pot to the
power-supply ground and VCA ground; connect the other end-terminal to +10 VDC, and
connect the wiper to the VCA control input of your choice (VCA1, VCA2, and so on).
3.3 Wiring to an External Variable DC Voltage Source
The VCA-MC control input is the pin labeled VCA1, VCA2, and so on. It is possible to drive
the control input from an external voltage source such as a Crestron control system. Con-
nect a variable voltage source (0-10 VDC) between the ground pin and control input on the
MC-VCA module. No build-out resistance is required. DO NOT connect to the +10V pin.
The voltage range of the control input is 0 TO 10 VDC. If this range is
exceeded, proper operation is not guaranteed and damage may result to the
VCA card or amplifier.
It is not recommended to draw more than 20mA from the 10V supply. (20mA is approxi-
mately equivalent to having a 5 k ohm potentiometer connected to each channel of an 8-
channel amplifier. Crown-supplied VCAP panels are equipped with 5 k ohm potentiome-
ters). The 10V supply will survive a direct short.

NOTE: When connecting your DC supply to the control pin and ground pin, be sure to avoid
ground loops. The control input filters out most AC voltages but a ground loop can modulate
the gain element of the VCA if the interference is of great enough amplitude.
3.4 Wiring for Multi-Channel Control
Often it is beneficial to control multiple amplifier channels with one control. For example,
some channels of the amplifier may be driving full-range loudspeakers, and other channels
driving subwoofers — all for the same room. In this case, it is convenient to control all of
those channels with the same control. Also, for correct operation when channels are bridged,
control inputs for the bridged channel pairs should always be wired together.
To electrically tie control inputs together, connect the control inputs of the channels together
with a jumper wire, as shown in Figure 3.3. Connect the tied combination to the VCAP wall
panel, or to the external voltage source.
It is recommended (but not mandatory) that the control inputs of bridged channels be electri-
cally tied together even if the VCA option is not used for that channel pair. Wire used to con-
nect two control inputs together should be as short as possible.

4 Operation
4.1 Operation Using the VCAP Wall-Mount Level Control
1. Turn the amplifier's back panel attenuator fully counterclockwise (off).
2. Unplug the connections to the VCA-MC module if they have been previously installed.
Remember that each connector has two channels on it. Don't unplug the VCA control for
a channel that is in use, because full volume will be sent to that zone since the
VCA attenuation is 0dB when nothing is connected!
3. Turn on your audio source. Set its output level to the maximum value you expect to use it
at. You should not hear any sound yet.
4. Slowly turn the amplifier attenuator clockwise until the system's volume is at the maxi-
mum value you want it to operate at. (Remember to refer to the power rating of the speakers.)
If the sound from your speakers is distorted within the first several detents, consider
decreasing the output level of your audio source.
5. The volume limit of the system is now set. This volume limit is relative to the input level
you just used to set it. If the input level from the audio source increases, so will the output
level of the amplifier. The volume limit is not an absolute limiter.
6. Turn off the amplifier.
7. Plug the VCA control (potentiometer or independent 0-10V DC source) into the VCA-MC
module.
8. Turn the amplifier on.
The VCA level control can now be used to set the system volume at any level between off and
the “volume limit” you just set. See Table 1.

Detent 0 is full counterclockwise. Dentent 30 is full clockwise. Note: This table is for refer-
ence only. Actual attenuation may vary ± 1 dB.
4.1.1 Troubleshooting
If the amplifier gain does not respond to the wall-mount potentiometer, a miswire is sus-
pect. Check the pinout at both ends of the cable. Make sure that each potentiometer is wired
to the correct channel’s VCA control input (VCA1, VCA2, etc.). Check that the +10V and
ground connections are made properly.
If the operation of the VCA control is inverted (i.e., full volume when the control is full coun-
terclockwise), check the VCA control wiring (refer to Section 3).

VCA-MC Series Amplifier Accessories

4.2 Operation Using Your Own Potentiometer or an External 10VDC Variable
Source
1. Turn the amplifier's back panel attenuator fully counterclockwise (off).
2. Unplug the connections to the VCA-MC module if they have been previously installed.
Remember that each connector has two channels on it. Don't unplug the VCA control
for a channel that is in use, because full volume will be sent to that zone since
the VCA attenuation is 0dB when nothing is connected!
3. Turn on your audio source. Set its output level to the maximum value you expect to use it
at. You should not hear any sound yet.
4. Slowly turn the amplifier attenuator clockwise until the system's volume is at the maxi-
mum value you want it to operate at. (Remember to refer to the power rating of the speak-
ers.) If the sound from your speakers is distorted within the first several detents, consider
decreasing the output level of your audio source.
5. The volume limit of the system is now set. This volume limit is relative to the input level
you just used to set it. If the input level from the audio source increases, so will the output
level of the amplifier. The volume limit is not an absolute limiter.
6. Turn off the amplifier.
7. Plug the VCA control (potentiometer or independent 0-10V DC source) into the VCA-MC
module.
8. Turn the amplifier on.
Using the potentiometer or the DC supply control, set the supply voltage to achieve the
desired attenuation according to the equation below:
Vc = Attn (dB) / (–7)
[Vc is the dc control voltage; Attn (dB) is the attenuation in decibels.]
0 VDC results in no attenuation (0 dB).
10 VDC results in full attenuation (–70 dB).
4.2.1 Troubleshooting
If the amplifier volume does not respond to the external DC supply, a miswire is suspect.
Check the pinout at both ends of the cable. Check that the +10V and ground connections are
made properly. If you are using an external 10VDC variable supply, make sure that the sup-
ply is switched on and is wired to the correct channel’s VCA control input (VCA1, VCA2,
etc.). If you are using your own potentiometer, check that it is wired as in Figure 3.2.
If the operation of the VCA control is inverted (i.e., full volume when the control is fully
counterclockwise), check the VCA control wiring (refer to Section 3).

VCA-MC Series Amplifier Accessories
Operation Manual
5 Theory of Operation
The amplifier attenuator and the VCA attenuator are in series (Figure 5.1). The gain of the
series combination is the sum of both attenuator settings. For example, if the amplifier
attenuator is set at –10 dB and the VCA attenuator is set at –33.3 dB, the total attenuation is
–43.3 dB. (See the CTs Multi-Channel Series Operation Manual for attenuation vs. detent of
the amplifier attenuator.)
Figure 5.1 System Block Diagram
This unique design allows the system designer to limit the power available to the user of
the VCA control. In the above example, the amplifier attenuator is set at –10dB. In this con-
figuration, the VCA control can vary the total amplifier gain only from a quiet –80dB to a
maximum of –10dB. This mode of operation keeps a novice user from turning up the sys-
tem too loud and damaging the loudspeakers.
