DOLBY DIGITAL / DTS
Digital recordings in Dolby Digital or DTS formats are reproduced via the channels employed in the original
recording (up to the maximum channels present in the current setup).
NOTE
• The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. The DVD
includes its own setup menu that (among other things) lets you select the default bit-stream format,
and includes an “Auto” setting that directs the player to choose the Dolby Digital/DTS signal whenever
these are available. In a few cases, you may have to set the player’s bit-stream manually to “DOLBY
DIGITAL: ON”. In the case of DVDs that carry both Dolby Digital and DTS, you will select one or the
other from the disc’s (not the player’s) main menu.
• While most Dolby Digital recordings are 5.1-channel surround productions, older examples may be
multichannel, 2-channel, or even monaural; the L70 will automatically reproduce the Dolby Digital
signal with the maximum number of channels available.
The table below indicates which SURROUND MODEs are available with the two types of audio signal
sources: digital- or analog-input 2-channel (whether the actual signal is monaural, stereo or surround-
encoded), and digital-multichannel (Dolby Digital or DTS). Where a SURROUND MODE is not available to
a given signal source, it will not appear in the selection rotation.

SELECTING SURROUND MODES
Keying the HTR L70 remote’s “SURR MODE” button steps through each of the L70’s SURROUND MODEs
available to the current input signal. It also momentarily displays the SURROUND MODE in the OSD.
NOTE
Changing the type of input signal may automatically change the SURROUND MODE: If the new signal
is a Dolby Digital or DTS recording, it will automatically invoke its native mode. The reverse is also true
if Dolby Digital or DTS was previously selected.
