INFORMATION ON THE HR-SSOOOU'S AUDIO SYSTEM
Hi-Fi and normal audio
To provide true hi-fi audio accompaniment to video entertain­
ment and, at the same time, compatibility with regular VHS
tapes, the H R-SSOOOU employs a unique audio recording
system. Hi-fi audio signals ( 2-channel) are recorded deep into
the tape's magnetic coating, and the video signal is recorded on
top of the audio signals in a shallower layer. At the same time,
another audio head records normal audio signals ( monaural)
onto the usual longitudinal audio track. Since this longitudinal
audio track is exactly the same as on monaural VHS tapes,
Tape pattern recorded with the HR-S5000U
Hi-fi audio recording and reproduction are available only
from the hi-fi audio track while the longitudinal audio track
provides normal audio.
MTS ( Multichannel Television Sound) compatibility
When stereo and SAP (Second Audio Program) programs are being received, the indicators light to inform you of the type of
broadcasts. Then you can select the desired soundtrack for recording with a single switch. The normal ( longitudinal) audio track is
monaural. Therefore, stereo programs are recorded in mono on the normal audio track. SAP programs can only be recorded on
the normal audio track.
Lights when an SAP program is being received. For record·
ing the SAP soundtrack, see "2ND AUD Setting" on the
right.

Note:
• Off-air MTS programs are received in accordance with the Broadcast Television Systems Committee (BTSC) standard. The
method of transmission of stereo programs via cable varies from area to area and may not be compatible with the BTSC
standard. Consult ygur local cable company for compatibility in your area.
VHS tapes recorded on the H R·SSOOOU can be played back on
other monaural VHS machines, and vice versa.

Note:
• You can record audio only (without recording any video signal) on the normal and hi·fi audio tracks. This means
you can record a continuous B·hour FM program onto a single cassette (T-160). For this purpose, make a SOURCE
setting for AUX and connect an audio source, such as an FM tuner, to the AUD I O I N connectors. Nothing should
be connected to the VIDEO IN or S-VIDEO IN connector.
