OUTPUT LEVEL RANGEOUTPUT LEVEL RANGE
These jumpers set the output signal level range for each
channel. They are set at the factory for a power amplifier input
sensitivity of between 90 mV and 1.23 V. If the power
amplifiers used in the installation are very sensitive (10 mV to
100 mV input sensitivity), it may be necessary to move these
jumpers to the LOW output position. If you are unsure of the
sensitivity of your power amplifiers, set to the LOW position
initially. If the HIGH output position is required this will be
determined during alignment.
Left LF Left Channel Low Frequency output (used for
both full-range and bi-amplified systems)
Left HF Left Channel High Frequency output (used
only in bi-amplified systems)
Center LF Center Channel Low Frequency output (used
for both full-range and bi-amplified systems)
Center HF Center Channel High Frequency output (used
only in bi-amplified systems)
Right LF Right Channel Low Frequency output (used for
both full-range and bi-amplified systems)
Right HF Right Channel High Frequency output (used
only in bi-amplified systems)
Ls Surround output (with optional Cat. No. 515
installed–Left surround)
Rs Right Surround channel output (with optional
Cat. No. 515 installed).
