Single-Ended Components
Single-ended components have RCA connectors. The VK-220 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-220 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-220 (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.
External 12V Trigger Input/Output
VK-220 is equipped with the external 12V trigger connectors – Input and Output. To
control the VK-220 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.
