Balanced Components
Use balanced XLR interconnects to connect the VK-250 to a balanced preamplifier. Input
connectors are clearly marked on the back panel.
Note: The VK-250 input XLR connectors are wired as follows:
Pin 1:
common/shield
Pin 2:
positive
Pin 3:

Single-Ended Components
Single-ended components have RCA connectors. The VK-250 power amplifier is
designed to work with either single-ended or balanced preamplifiers connected to its inputs.
All that is required to connect a single-ended preamplifier with RCA connectors to the
VK-250 inputs is the optional balanced to single-ended adapters. These adapters are
available from Balanced Audio Technology at a nominal charge.
Input Adapters:
RCA Female to XLR Male
Speaker Connections
There are two sets of high quality binding posts on the back panel of the VK-250 (one for
each channel). These can accommodate a wide variety of speaker cable terminals. You
can use a 7/16” wrench to tighten these binding posts, however excessive force should be
avoided to eliminate the chance of breakage.
Monoblock Connection: On VK-250M Power Monoblock either left or right output
connector can be used for speaker wires, or both, in case of bi-wiring.
External 12V Trigger Input/Output
VK-250 is equipped with the external 12V trigger connectors – Input and Output. To
control the VK-250 the external device must supply the standard 12V signal.
12V Trigger Output connector can be used to drive another device’s input for daisy-chain
operation of multiple units.
