Important Note: When bridging the CV Series amplifier at one of the distributed voltage outputs, it is
necessary to connect the Common connections for the distributed voltages together. The commons on
the secondary side of the output transformers are floating. This is not true for the low-impedance
outputs. Their respective commons are connected internally.
Power Sequencing
A three pin Euro style terminal and mating connector are supplied with each amplifier to allow
the amplifier power to be sequenced ON or OFF remotely. These terminals are located on the
rear panel of the amplifier. The three terminals are from left to right, the “Ground, Send and
Receive. (See Figure 9)
When used with more than one amplifier the “SEQUENCE” feature will turn ON or OFF the
amplifiers sequentially at about 0.5 second intervals, preventing a large turn on surge though
the AC mains supply that could possibly cause disruption of the flow of current through the AC mains.
Note: Use a remote supply of 12 to 15 VDC. Maximum current required is 20mA at turn-on,
drops to ~1mA after amp turns on.
Important NOTE: The SEND terminal on the Sequence connector has a +15Vdc potential
whenever the amplifier is “ON”. The User should take caution not to short this terminal to
‘Chassis Ground”. The +15Vdc supply, internal to the amplifier, could be damaged.
Turning A Single Amplifier ON / OFF
First, place the CV amplifier’s power switch in the Standby (fully down) position. Connect the positive side of a
5to15VDC >20mA supply to the “RCV” terminal of the SEQUENCE connector. Connect the negative side of the
supply to the “GROUND” terminal
of the sequence connector.
As long as the DC voltage is
present the amplifier will remain on.
Opening the circuit at the
“SEQUENCE” connectors
interrupts the DC voltage, and the
amplifier will turn off. If a switch is
used to control the “SEQUENCE”
circuit, it should be a SPST (single
pole single throw) switch, not a
momentary contact closure. A
control device such as a contact
closure contained within a system
such as Creston®, AMX® or
Panja®, as examples, can be used
to remotely control the Power
ON/OFF function of the amplifier.
The contact closure must be a
latching type and not a momentary
contact closure.

Sequencing Multiple Amplifiers ON / OFF
When using multiple amplifiers that utilize the “SEQUENCE” feature of the CV Series amplifiers, connect the
amplifiers in the following manner. Starting with the first amplifier in the sequence to be turned on, connect the
positive side of a 5 to15 VDC >20mA supply to the “RCV” terminal. Next connect a wire from the “SND” terminal
of the first amplifier to the “RCV” terminal of the next amplifier to be turned on. Continue in this manner until all
