Parasound Halo C1 Controller - Manual (Page 17)

Page 1 of the C1/C2 Menu
Of the items on the Page 1 menu, the MODE–, +MODE,
DIM, and ZONE functions have already been discussed in the
last chapter, but the others are new. Here’s what they do:
• THX ® : With most modes, this key simply switches THX
Cinema processing on or off (see “Technically Speaking”). In
Direct mode, however, pressing it again may select other THX
modes, depending on the speakers selected in “Speaker
Setup/Size” and choices made in “THX Audio Setup.” If one or
more surround-back speakers are present, pressing this key
again will select the THX Surround EX mode; if two surround-
back speakers are present, repeated pressings will bring up
THX Ultra2 Cinema and then THX MusicMode. The C 1 will
then cycle through these three modes for each press of the
THX key, returning to Direct (and switching THX processing
off) when you press either Mode key.
THX Surround EX will not activate if no surround-back speak-
ers were selected during Setup, or the source signal does not include surround channels. In the
first instance, the display will read “No Surround-back Speakers”; in the second, it will read
“Incompatible Source.”
When THX modes are selected for an incompatible source or speaker setup, the C 1 will
remember the selection and will automatically apply it if the setup is changed or a compatible
source is selected.
• TAPE: Switches the main-zone audio output to the signal from the Play/In jacks of the rear
panel’s Tape Monitor section, and to stereo mode. This allows you to hear not only the input sig-
nal being fed to your recorder but, by pressing the key, the output from the same recorder.
If an analog tape recorder with separate recording and playback heads is connected to these
jacks, you can use this feature to hear the signal from the tape you’ve just recorded, delayed by
the fraction of a second it takes the tape to travel from the recording to the playback head.
If a digital recorder’s analog input and output jacks are connected to these jacks, using this fea-
ture will let you check the signal after it’s been through the recorder’s A/D and D/A converters,
to be sure the signal level does not reach overload levels. (Distortion, which increases gradually
as analog tapes overload becomes obnoxiously high almost at once when digital converters
reach their overload point.) Note that signals from the digital inputs are not sent to the Rec/Out
analog jack and should be recorded digitally from one of the digital outputs on the C 1.
• DYN, or Dynamic Range, activates Dolby’s “Late Night” mode when the C 1 is playing Dolby Digital
soundtracks. This reduces the dynamic range of digital movie soundtracks by making the soft sounds
louder and the loud sounds softer. In late-night listening, this enables you to hear all the dialog with-
out awakening your family (or neighbors) when the sound effects get loud. With anything other than
Dolby digital signals, the displays will read “Incompatible source” when you press this key.
• EBASS, or Enhanced Bass, is for use in systems that have some “Large” speakers, i.e. those
able to deliver adequate bass on their own. (See “Size” under “Speaker Setup,” next chapter).
When EBASS is off, bass from the program channels with “Large” speakers goes only to those
speakers, and the subwoofer receives bass from the LFE (Low-Frequency Effects) channel and
bass from the channels whose speakers you selected as “Small” during setup. With EBASS on,
bass from all program channels goes to the subwoofer as well. This can lead to a bass increase,
which will probably be more welcome with movie soundtracks and with pop and rock music
than with classical music. However, in some rooms it can lead to decreased bass at specific fre-
quencies, caused by interference between the subwoofer’s bass output and that of the other
speakers; if that occurs, you can try reversing the polarity of your sub or simply shut EBASS off.
• TEST: Sends a calibration-noise signal to each channel in turn, for use in checking channel iden-
tification and setting speaker levels. For channel identification, the signal advances from channel
to channel every 2 seconds, starting from the left front and moving clockwise to the center,
