523 DUAL-MONAURAL PREAMPLIFIER / OWNER’S MANUAL
ENGLISH
In the past, the differing number of channels in each component
made integration between two-channel and multichannel
components difficult. Sending multichannel processor output
signals to a stereo Preamplifier distorts calibrated processor output
levels. Multichannel processor volume controls adjust the relative
volume level of all channels in unison. However, stereo Preamplifier
volume controls adjust the relative volume level of just the front left
and right channels, leaving the center, surround, and subwoofer
channels unaffected.
To avoid these problems when the preamplifier is connected with an
associated surround sound processor, the SSP Mode allows selected
input sources to pass through the preamp without interference. When
SSP Mode is activated, the preamp’s volume control is deactivated
to prevent the preamp from distorting channel balance. As a result,
the processor controls the relative volume level of all channels while
maintaining its calibrated output levels.
To connect the preamp with a surround sound processor:
1. Make sure the preamplifier and all associated components are
powered off and disconnected from electrical outlets.
2. Connect the output connectors on the surround-sound source
component to the input connectors on the surround-sound
processor. For example, if the source component is a Blu-ray
disc player, connect it to the appropriate input connectors on the
surround sound processor.
3. Connect the front left and right output connectors on the processor
to the desired analog input connectors on the

preamplifier. For best performance, use balanced connections
whenever possible.
4. Connect the center, surround, and subwoofer output connectors
on the processor to the appropriate input connectors on the power
amplifier(s).
5. Connect the preamplifier’s outputs to the amplifier(s) connected
to the system’s left and right (main) speakers.
To activate SSP Mode for a selected input:
CAUTION: Before activating the SSP mode for any input, set
the associated surround sound processor volume control to a
reasonable level to prevent sending dangerous signal levels to the
associated loudspeakers.
1. Activate the Setup menu by pressing the Setup button
2. Select Input Setup, and press Enter
3. Select the analog input you wish to configure for SSP use, and
press Enter
4. Select SSP, and press Enter
5. Set the SSP parameter to On, and press Enter
6. Press the Setup button four times to step backward through the
menu hierarchy and exit the Setup menu
