c) Satellite Filter
The satellites in a system can be driven full range or with a 85 Hz high
pass as recommended by Dolby® laboratories for use in surround set-
ups. Recommendation: If possible the main signal should go into the
Subwoofer. Connect your satellites to the Subwoofer output, either
via XLR symmetrical or RCA asymmetrical. In many cases, clarity and
dynamic range of the speakers can be improved if they do not reproduce
very low frequencies since they do not have to deliver big amplitudes.
Please note: If you alter the frequency it is advisable to check if an alteration
of the phase improves the sound quality.
d) Sub Level
This controls the Input Sensitivity from -60dB to +6dB
relative to 775mV when used via the balanced XLR input
or relative to 250mV when used via the unbalanced Cinch
(RCA) input.
e) Sub Filter
The upper frequency limit of the unit is variable and can be set to
any value between 50 and 150Hz. The 85Hz marker indicates the
recommendation of Dolby® labs for surround sound settings. In practice
a slightly lower crossover frequency delivers tighter bass response, for
typical near-midfield monitors we recommend a 12 or 11 clock position,
meaning 70 to 75Hz as upper limit or, to be more exact, -3dB point in the
frequency response.
Please note: These settings do not have a precise character, as different
satellites and different room acoustics lead to results that cannot be
predicted.
