Status:
The unit goes into Balance Setting mode while either the Balance L
or the Balance R button is held down or the Balance button is
pressed.
16. User toggles between suppressing and displaying out-of-balance display
information (Front Panel or RS-232 port)
User may not want to display permanent out of balance conditions all the time.
User input:
User presses mute button while holding down balance button.
Addressable through RS-232 port also – see specific section for
command structure.
Indication:
Left or right bar on front panel display toggles between display and
no display.
Status:
No functional change in unit.
17. User changes absolute phase (Remote or Front Panel)
Absolute phase between positive wave fronts and negative rarefactions of sound
(watch the woofer of your loudspeaker on bass notes) varies from recording to
recording (and sometimes within different tracks on a recording), sometimes by
design, and sometimes in error. High resolution systems are easily able to resolve these
anomalies, and the user may wish to correct the problem by changing the phase of the
signal.
User input:
User depresses Phase button on front panel or remote, or sends a
discrete phase or phase reverse signal from external remote.
Indication:
The LED for phase toggles between 0
0
(off) and 180
0
(red).
Status:
The unit changes output polarity with respect to input.
18. User fades signal (remote only) (unmated only)
Fading/lowering the signal quickly (as opposed to muting it to zero level) is sometimes
desired, and is faster to lower the volume than the sequential volume control.
User input:
User presses Fade button on remote control.
Indication:
Volume level indication on front panel jumps directly to 20.
Status:
Output volume level drops directly to volume level of 20 (including
offset.) If the volume level is less than 20, or if the unit is in Mute
mode, pressing the Fade button will not change the level.
19. User monitors input while recording (any input) (Front Panel only)
If the user wants to be able to listen to the recording as it is being made on such an
equipped tape deck then the monitor function is used. The selected input being
recorded will still be routed to the record output (which is connected to the input on
