Bypass Button; Master Volume - Bryston SP 1 Series Instructions Manual

13. THX Button
Selecting this function (LED illuminated) will automatically
incorporate the THX post processing option for all surround
modes.
(please SEE Appendix B FOR MORE Information)
NOTE: When you choose to watch a DTS encoded DVD or LD movie,
please be sure that the SP1 is in the DTS Movie mode. You may choose
to use the THX features to enhance playback of DTS bitstreams for
motion pictures. Sources originally mixed for a large environment such
as motion pictures may benefit from THX processing.

14. Bypass Button

This button toggles the unit in and out of bypass mode. In
bypass mode (LED illuminated) all of the DSP circuitry is
bypassed, allowing a completely analog circuit path, identical
to the reference standard Bryston BP-25 pre-amplifier.
Only standard format Stereo operation is permitted in this
mode - all other functions are disabled.
15. Analog Balance
This control governs the balance of the analog bypass circuit.
It will only function if the SP1 is in bypass mode.

16. Master Volume

This is the Large Knob located on the far right side of the
front panel. It controls the Master Volume in all modes. It is
fully motorized and can be operated from the remote control
or by hand. It is the final level setting control on the SP1, and
determines what output level will be supplied to the
connected power amplifiers, but not the tape/recording
outputs. It takes into account any speaker level trim
adjustments made during the SP1's setup.
