Format determines if the digital-channel output follows the professional AES3 or
consumer SPDIF standard.
We expect that AES will be appropriate for almost all users, but some
consumer sound cards may require SPDIF.
BS.1770 Safety Limiter ON/OFF activates or defeats the BS.1770 Safety Limiter,
which is applied only to the digital radio processing. This control affects the behav-
ior of the digital output receiving the HD feed (see step 12 on page 2-35).
BS.1770 Integration Time sets the integration time of the BS.1770 Safety Limiter
and the "Integrated" BS.1770 loudness indication (the solid bar on the L

Included with each preset in the "HD Limiting" page in PC Remote. The only HD
controls described in this section and shown in Table 3-12 have no FM analog coun-
terparts. There are many other HD controls that have analog FM counterparts. These
are described in earlier parts of Section 3 in this manual.
FM HD Control Coupling determines if audio controls affecting the HD equalizer
and HD multiband limiter will track their counterparts in the FM analog processing
chain or if the HD and FM controls can be adjusted separately. Each preset contains
its own setting for this control, so some presets may be coupled while others are in-
dependent. The FM HD mode causes almost all HD controls to track the settings of
their FM counterparts. Only the controls in the HD L
