Configure the digital filter for the audio
DAC. Linear Phase (Slow Roll-Off) is the
default setting.
The Audiolab 9000A ESS ES9038PRO
SABRE DAC allows for detailed tuning of
the audio experience. The DAC
reconstruction filter is a critical part of
refining the sound of a system that
depends on listening taste, program
material, and equipment set-up.
• Linear Phase (Fast Roll-Off): This is the most common filter with clean overall
suppression and excellent rejection, best for music with large transients. Provides
crisp clean highs.
• Linear Phase (Slow Roll-Off): A low group delay and symmetrical input response with
less ringing than ‘Linear-phase fast roll-off’. It offers punchier bass than ‘Linear-phase
fast roll-off’, with clean highs. (Default)
• Minimum Phase (Fast Roll-Off): This offer minimal pre-ringing. It is usually preferred
for imaging and sound stages. It offers no aliasing in the frequency domain and
stronger bass than ‘Linear Phase’, with clean highs.
• Minimum Phase (Slow Roll-Off): A Non-Symmetrical filter designed to minimise
pre-ringing. It offers a strong punchy bass with a good transient attack.
• Hybrid: This is the combination of ‘Linear-phase’ and ‘Minimum-phase’. It offers a
fast transient attack, strong punchy bass and crisp highs.
DPLL
This setting is used for changing the
bandwidth of the digital phase lock loop
of the D/A converter to accommodate
different levels of jitter on the incoming
SPDIF signal.
Normal mode should be selected for
signals with low jitter, while Wide mode
should be selected for signals with
abnormal jitter.
For best audio quality leave this setting at the default value Normal, only use Wide
for a given input if the system is having problems locking onto the source.
Upsampling
The 9000A will automatically upsample
the incoming digital audio signal
(SPDIF or PC USB) to 352.8KHz or 384KHz.
The upsampling can be turned OFF if
required.
Balance
Adjust the Left and Right balance of the
9000A audio output.
