Analog Connections
Input Connectors: The SP20 provides ve pairs of single-ended input
connectors: SE1 - 4, PHONO and MONITOR. Please note that input SE4
can be selected as a unity gain input; in this case, SE4 should only be
connected to a component with a volume control (such as a home theater
processor). For further information about the SE4 unity gain (PROC mode),
see the section ‘PROC Mode’ on page 16. In addition, there are two pairs
of balanced input connectors: BAL1 and BAL2.
Never connect a source with a xed level output (DVD player, tuner, CD
player, etc.) to the unity gain input. This could cause serious damage to the
ampliers or speakers in your system.
Output Connectors: Two pairs of balanced and one pair of single-ended
main outputs are provided.
Record Output: The tape outputs should be connected to your recorder’s
‘Record’ or ‘Line’ inputs. These outputs provide a xed-level two-channel
signal (L, R) to your recorder from whichever input is selected. The xed
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. SE2 or
BAL1). 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.
IR Input: The IR input can be used to link the SP20 to an IR repeater
system with a standard mono 1/8” connector.
12V Trigger Jack: The +12V DC output connector provides the ability to
remotely turn on and off other linked components such as power ampliers
having similar capabilities.
