The unit fails to respond to the controls
-
•  While locking to a source or changing some settings (e.g. Filter), the
microcontroller inside the unit is busy and will not respond to new
commands for a few seconds. Turning DSD mode on and off occupies the
microcontroller for about 15 seconds.
•  Short mains supply drop-outs may cause the microcontroller to lock up.
Switch off the unit, wait 10 seconds then switch on again. If this does not
clear the fault, please contact your dealer.
•  The Remote Control disables the front panel controls.
The audio output is low or absent
-
•  Check that all cables are connected correctly and not damaged. Damaged
cables are a VERY common source of malfunctions!
•  Check that the source and destination equipments are switched on and
correctly set up.
•  Check that the unit is locked to the source you want to monitor.
• Ensure 
Mute
 is not enabled - LED off.
• Set 
the 
Volume
 control 0.0dB.
•  Ensure the source is sending audio data.
• If 
the 
Ref In
 menu item is set to 
ddC
, change it to 
Route
. With PCM inputs,
DDC mode disables the analogue outputs.
The level trimmers on the rear panel do not change the output level
•  Ensure the trim tool or flat-bladed screwdriver you are using is narrow
enough to reach the adjuster (about 2.5mm or 0.1” diameter) and long
enough (at least 12mm or 0.5”).
•  The trimmer may be at the end of its travel - try turning it several times the
other way. It is a 20-turn device.
•  The level trimmers do NOT affect the unbalanced outputs.
The Left and Right channels are swapped
• Check 
that 
Flip
 is 
Off
.
•  Check that the audio output cables are not reversed.
•  Check that the channels are not swapped elsewhere in the system.
• In 
Dual AES
 mode, ensure that the 
AES 1
 (or 
AES 3
) input is connected to
the output on the source equipment for the Left channel data (probably
labelled AES 1, AES A or Left) and 
AES 2
 (or 
AES 4
) input is connected to
the output on the source equipment for the Right channel data (probably
labelled AES 2, AES B or Right). See the manual of the source equipment
for information.
• In 
Quad AES
 or 4-wire DSD modes, ensure that 
AES 1, 2, 3 & 4
 inputs are
correctly connected to the corresponding outputs on the source equipment.
See the manual of the destination equipment for information.
• In 
SDIF
 or 
DSD
 modes, ensure the 
Ch1
 and 
Ch2
 inputs are connected
correctly.
One output channel is low or absent
-
•  Check that all cables are connected correctly and not damaged. Damaged
cables are a VERY common source of malfunctions!
•  Check that the balance is not offset elsewhere in the system.
•  If the level trimmers on the rear panel have been adjusted, check that one
has not been set much lower than the other.
• In 
SDIF
 or 
DSD
 modes, ensure both 
Ch1
 and 
Ch2
 inputs as well as the
Word Clock are connected correctly.
