Input Connections
Best results will be obtained when connecting the VK-500 to a balanced preamplifier.
However, the VK-500 is designed to accept either balanced or single-ended inputs.
Balanced Components
Use balanced XLR interconnects to connect the VK-500 to balanced preamplifier. Input
connectors are clearly marked on the back panel.
Note: The VK-500 input XLR connectors are wired as follows:
Pin 1:
common/shield
Pin 2:
positive
Pin 3:
negative
Single-Ended Components
Single-ended components have RCA connectors. The VK-500 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-500’s 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-500 (one for
each channel). These can accommodate a wide variety of speaker cable terminals. You
can use a 1/2” wrench to tighten these binding posts, however excessive force should be
avoided to eliminate the chance of breakage.
