(8) Single/Dual switch -
The Single/Dual switch specifies whether AES/EBU Single Wire or Dual Wire
mode is used.
(
see page 28 for more information
) When the button is pressed in, AES/EBU Dual
Wire mode is used. When the button is out, AES/EBU Single Wire mode is used. Note: This switch has
no effect on the SPDIF input. However, the SPDIF output will transmit the same signal as the AES “A”
output.
(
see #3 on page 9 and #6 on page 10
)
(9) Digital Outputs Source Select -
This three-position knob specifies the signal that is routed to the
digital outputs. The signal source selected here will be routed to all digital outputs (AES, SPDIF, and
ADAT optical) simultaneously. This knob is normally set to ADC during all operations except
transcoding.
(
see pages 23 - 24 for more information
)
AES/SPDIF In -
When the Digital Outputs knob is set to AES/SPDIF In, the digital signal
arriving at the rear panel AES or SPDIF digital input
(
see #3 on page 9 and #6 on page 10
) is
routed to all digital outputs, as
determined by the setting of the AES/SPDIF switch. (
see #7
on page 7
)
ADAT In -
When the Digital Outputs knob is set to ADAT In, the digital signal arriving at the
rear panel ADAT optical digital input
(
see #11 on page 10
) is routed to all digital outputs.
ADC -
When the Digital Outputs knob is set to ADC, the signals arriving at the rear panel
analog inputs
(
see #13 on page 11
) are converted and delivered to the digital outputs.
(10) Power lamp -
The Power Lamp glows blue when the proper AC voltage is connected and the
power switch is in the up (I) position. Note that, after the Power Switch is turned on, the Power Lamp
stays off for about two seconds while the 2192 power conditioner circuits perform their initial
calibrations.
(11) Power switch -
Turns the 2192 power on or off. Power is on when the switch is in the up (I)
position. Approximately two seconds after turning power on, the Power Lamp lights blue. When the
switch is down (O), AC power is completely disconnected from the internal power supply, and only the
safety ground remains connected to the chassis.
Neither the AES/SPDIF switch nor the Single/Dual switch has any effect unless the Clock,
Digital Outputs Source Select, and/or Analog Outputs DAC Source Select knobs are set to
AES/SPDIF.
If the Power Lamp does not come on after the initial two-second delay, check that the
2192 is connected to a 100-240VAC 50-60Hz AC power source. If the power still does not
come on, it is possible that the internal protection fuse has blown, in which case the 2192
needs to be serviced by a qualified service technician.
