Crackles or pops occur while playing music
• The source may have a high level of jitter. Try setting the PLL parameter to
PLL:Wide. See page 29.
• The digital audio cable connecting Delius to the source may be damaged,
intermittent or of the wrong type. Some expensive cables are not correctly
designed for digital audio use. Try another cable.
• The CD may be dirty - clean it very carefully using a radial motion.
• The disk / tape may be damaged or contain corrupted data.
• The audio output level may be enough to overload a preamplifier or power
amplifier.
Erratic operation when locked to 96 or 88.2kS/s on Toslink or ST inputs
• Check your optical connections are clean and properly installed.
• The Toslink and ST receiver devices are industry standard types which are
not guaranteed to operate correctly at 96 or 88.2kS/s. Connect to a different
input instead.
The unit will not decode Dual AES
• Dual AES mode may be disabled. Open the menu and set the Dual AES
page to On (see page 25). Connect a valid 88.2, 96, 176.4 or 192kS/s Dual
AES source to both AES 1 and AES 2 inputs. Press the Input selector
button repeatedly until both AES1 and AES2 indicators are lit.
• Your source equipment may have two AES outputs but might not be
capable of Dual AES operation. Check the manual for the source
equipment.
The unit drops out of Dual AES mode into AES1 or AES2
• Dual AES mode is only available if AES data streams are available on both
AES 1 and AES 2 inputs. If either of these are interrupted or become
corrupted while in Dual AES mode, the unit may default to single AES mode
and select the valid input. Check for faulty wiring to the input which has
been deselected. Once both data streams are stable again, Dual AES mode
may be selected using the Input button or the Remote Control. See page
25.
• If you are driving Delius direct from an Upsampler always set to output Dual
AES, you may find that changing inputs on the Upsampler causes Delius to
fall out of Dual AES mode. To prevent this, Delius may be locked in Dual
AES mode. Open the menu and page through until you reach the Dual AES
page. Change the setting to Lock. Select AES 1 or AES 2 input on Delius
and it will enter Dual AES mode automatically (see page 25).
A digital recorder fails to record from the REC Output
• If Delius is selected to an SPDIF input (RCA, BNC, ST or TOSLINK) and
the source data (CD for example) is copy protected, your recorder will be
prevented from recording the data. This prevents copyright infringement.
Note that AES data streams have no Copy Prohibit flag.
• In some DAT machines, the digital input is connected directly to a digital
output without buffering. This arrangement does not comply with the
IEC60958 standard. Connecting another device to this may overload Delius’
REC output and corrupt the digital data.
• The REC output is usable with single AES, RCA, BNC, Toslink or ST
inputs ONLY.
