HP Sources Description
Tracks A, B (MS) Stereo monitoring of discrete M (mid) and S (side) track pairs. Highlighted media is source of monitor
program. Upon playback will function as MS track monitor.
Monitor A,B (MS) Stereo monitoring of playback (post-record) discrete M (mid) and S (side) track pairs. Highlighted
media is source of monitor program. When not in playback, headphones have no program.
Inputs 1+2, 1+2 Summed inputs appear in each ear for summed mono monitoring of both inputs.
Tracks A+B, A+B Summed tracks appear in each ear forsummed mono monitoring of both tracks.
When tracks (A or B) are monitored in headphones, audio assigned to the tracks is heard in headphones
during recording. During playback the recorded track audio is heard in headphones.
To set the available headphone source options for headphone monitoring enter the HP: Monitor
modes menu. Once you enter the Monitor Modes menu you will immediately be in slot-1. Rotate the
Rotary Switch to select the source you wish to appear first in your Headphone monitor list. Once the
chosen source appears, press the Rotary Switch or the soft key ENTER (tone) key to move to the next
slot. Continue down the list to select the source for each slot in the list. Once all sources have been
chosen, press (done). This will exit the headphone monitor mode setup. You can exit the selection
process by pressing the stop or cancel (backlight) key at any time.
If DONE is pressed in the first headphone slot, the 722 will select a single option (Tracks A, B) for head-
phone monitoring. The 10 factory presets will be erased.
MS Stereo Monitoring
The MS stereo mode decodes discrete Mid-Side stereo signals to a left/right stereo signal for moni-
toring purposes. This allows for a proper stereo signal to be monitored in the field while discrete
M and S signals are recorded for later post production. For the MS decoder to operate properly, the
Mid signal is connected to input 1 and the Side signal is connected to input 2. The amount of stereo
“spread” is fixed to a 50/50 percentage from Mid to Side signal.
If MS is selected for input linking, do not use MS stereo monitoring. This would result in two MS decod-
ers being inserted in the signal path. The resulting audio in the headphones would be the discrete M and
S signals!
Rotary Switch Behavior
The action of the Rotary Switch during recording and playback is set from among the three available
options:
• Disabled: pushing the Rotary Switch has no effect.
• Selects Favorite Mode: places the headphone source into the mode selected in the HP Favorite
menu.
• Playback/Monitor Drive Select: pushing the Rotary Switch toggles between CompactFlash,
internal hard drive, and external hard drives for playback and monitoring while recording.
