4. Remote Level
The Remote Level Connector is used to connect a Remote Level Control to the
CV Series amplifier. The connector is a Euro Style connector with the following
connection points, from left to right. (See Figure 5)
RTN – Return, CV2 – Control Voltage for Channel 2 on Dual Channel models,
CV1 – Control Voltage for Channel 1, and +5V volt send from the VCA package.
More information on how to connect this feature is available later in this manual
5. Standard Input Module
A Standard Input Module is included with each CV Series amplifier. The Standard Input Module allows
the use of a balanced or unbalanced line level input via a panel mounted female XLR connector or a
three pin Euro Style connector. The sensitivity of the input is adjustable with a jumper selection on the
input card PCB at either a .775V
RMS
or 1.5V
RMS
input level. An additional jumper selection is available to
select Bridged Mono mode, Normal Dual Channel input mode or Parallel Mono input mode. (See
Appendix B) In the Bridged and Parallel input mode, a single input will drive both channels on a dual
channel amplifier. Both a Single channel (MSSI) and Dual channel (MSDI) input cards are available and
are provide with the appropriate CV Series amplifier.
Caution! Before removing the input module for any reason, make certain that the amplifier’s AC mains
are first switched OFF or disconnected.
6. XLR Connector
Female XLR connectors are provided on Standard Input Modules to receive Balanced or Unbalanced line
level input signals. Pin 2 is (+) hot, Pin 3 is (-) negative and Pin 1 is chassis ground. To use the XLR for
an unbalanced input signal, connect the (+) signal to Pin 2, and the shield to Pin 1 with a jumper from Pin
1 to Pin 3.
7. Euro Connector
A three-pin Euro Style connector is provided on the Standard Input Module to receive a Balanced or
Unbalanced line level input signal. Counting from left to right, Pin 1 is (+), Pin 2 is (-) and Pin 3 is chassis
ground. For an unbalanced input signal connect pin 1 to (+), Pin 2 to the Shield and connect a jumper
from Pin 3 to Pin 2.
8. AC Line Cord Receptacle
An IEC type AC line cord receptacle is provided to receive the line cord included with the CV Series
amplifier. An appropriate line cord termination is provided based on the country of destination with each
