VRM12 – 7

4. CONNECTIONS

WARNING: To prevent the risk of electric shock, do not connect the loudspeaker

with the amplier switched on.

The loudspeaker has two identical Speakon connectors, which are wired as follows:

Inputs:

• Pin 1+ is the positive (+) input,

and connects to the positive (+)

output of your power amplier.

• Pin 1– is the negative (–) input,

and connects to the negative

(–) output of your power

amplier.

• Pin 1+ and 1– of one Speakon are connected internally to the VRM12 crossover’s

input. They are also connected internally to Pin 1+ and 1– of the other Speakon,

which can be used to send speaker-level power to another VRM12.

Through Outputs:

• Pin 2+ is the positive (+) through output.

• Pin 2– is the negative (–) through output.

• Pin 2+ and 2– are not connected internally to the VRM12 crossover’s input. They are

only connected internally to Pin 2+ and 2– of the other Speakon.

Connection Examples:

• Using the second Speakon (Pin 1+,1-) to connect a second VRM12 in parallel.

Make sure that the total average impedance of your loudspeakers does not drop

below the recommended minimum load impedance of your power amplier.

For example, when two VRM12s are wired as shown above, the total average

impedance is 4 ohm. For three VRM12s, the total average is 2.67 ohm. Make sure

your amplier can handle this load impedance, or it may become overloaded.
