Balanced Audio VK-655SE - Manual (Page 7)

Balanced Components
Use balanced XLR interconnects to connect the VK-655SE to a balanced
preamplifier. Input connectors are clearly marked on the back panel.
Note: The VK-655SE 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-655SE 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-655SE inputs is
the optional balanced to single-ended adapters. These adapters are available
from Balanced Audio Technology.
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-655SE (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.
Monoblock connection: On VK-655SEM Balanced Monoblock either left
or right channel output can be used to connect speaker wires, or both, in
case of bi-wiring.
External 12V Trigger Input/Output
VK-655SE is equipped with the external 12V trigger connectors – Input
and Output. To control the VK-655SE the external device must supply
the standard 12V signal.
