Connections

INPUT CONNECTORS: The Reference 10 provides
seven pairs of BAL/SE input connectors: 1, 2, 3, 4,
5, 6, and Processor. The BALANCED/SINGLE ENDED
selector (touch screen) or BAL/SE (remote) should be
selected to match the type of connection used (BAL
or SE) on each input.
Connect either the BAL or SE connectors for each
input. Never connect the BAL and SE connectors
simultaneously for each input.
OUTPUT CONNECTORS:
outputs are provided.
RECORD OUTPUT: The BAL/SE tape outputs should
be connected to your recorder's 'Record' or 'Line'
inputs. These outputs provide a fixed-level two-
channel signal (L, R) to your recorder from whichever
input is selected. The non-variable output level will
be the same as the output of the selected source.
It is possible to dub or copy from one recorder to
another by connecting the output of the source
recorder to an unused set of stereo inputs (e.g. 5 or
6). The signal will then be routed to the Record Out
connectors when that input source is selected.
RS-232 Connection: The RS-232 connection allows
for remote control via systems such as Creston or
other automation systems.
12V IN/OUT REMOTE START JACKS:
input/output jacks provide the ability to remotely
turn on and off other linked components such as
power amplifiers having similar capabilities.

Installation Instructions

While the Reference 10 does not dissipate an
unusual amount of heat, it is important that it be
provided with reasonable airflow to assure long,
trouble-free operation.
