Parasound Halo C1 Controller manual Play some music that you know has high peak levels

ADJUSTMENTS, MENUS, AND SETUP continued 33

adjustments controlled by the “Preset setup” submenu under “Audio setup.” When you select a source that has an associated preset, the preset’s bass and treble settings replace those made on the main “Audio setup” screen and the center, surround, and subwoofer level changes are added to the values selected in “Level setup.” If you use the tone and speaker level adjustments on the Master remote to change these settings, your changes will persist as long as the C 1 is set to that input but will be erased from memory and lost as soon as you change to another input.

A source set to “No change” will use the global settings made in the “Audio setup” menu until you change its settings with the Master remote, and changes made that way will be remem- bered whenever you come back to this source.

A source set to “Flat trims” will use the global settings made in the “Audio setup” menu until you change them with the Master remote, and will return to the global settings once you have changed sources.

Analog monitor is used to adjust input sensitivity for analog audio signals, to insure against overloading the analog-to-digital converters in the C 1, and also to allow balancing analog sources so that volume will not shift annoyingly when you switch between them.

To use this feature, select the desired analog audio source on the “Source setup screen,” then select “Analog monitor.” This will change the on-screen display to a level scale flanked by fluctu- ating level-meter bars for each channel, plus shorter bars that linger briefly to help you see the most recent peak levels:

replaced by “Digital input” and no adjustments can be made.)

Component video lets you associate the selected input with any of the three component-video inputs on the C 1. Note that this is true even of the Audio 1 through Audio 4 inputs, which are not associated with any composite or S-video inputs.

Balanced source assigns the balanced analog Left and Right inputs to one of the ten main sources, not necessarily the one selected in the “Source” line of the “Source setup” screen. If you are not using the balanced input for any source, set this to “Off.”

Balanced routing offers two routes from the balanced input to the outputs of the C 1. “Bypass” gives the shortest, most direct route possible through the C 1, with the signal passing only through the volume controller, and then to the left and right front channel balanced outputs (and to the “Rec/Out” jacks in the “Tape Monitor” area of the C 1 rear panel). In this mode, the signal is unaffected by tone controls and other adjustments and surround modes are unavailable. In “DSP” mode, all adjustments and surround modes can be used.
