Operating instructions
28 
Important: At this setting, the digital signal (AES or S/PDIF) routed to the digital outputs is 
determined by the AES/SPDIF switch. 
ADAT In 
When the Digital Outputs knob is set to ADAT In, the digital signal from the ADAT optical digital 
input (page 18) is routed to all digital outputs. 
ADC 
When the Digital Outputs knob is set to ADC, the signals at the analog inputs (page 18) are 
converted and delivered to the digital outputs. 
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: After the Power Switch is turned on, the Power Lamp stays off for about 2 seconds while the 
2192 power conditioner circuits perform their initial calibrations. 
Important: If the Power Lamp does not come on after the initial 2 second delay, please 
check that the AC line is plugged into 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, 
and the 2192 needs to be serviced by a qualified service technician. 
Power Switch 
The Power Switch activates the 2192. Power is on when the switch is in the up (I) position. 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. 
Important: Do not apply power to the 2192 unless the audio monitoring system volume 
is reduced to minimum. 
Important: Like all quality audio equipment, please allow the 2192 to warm up for 20 
minutes after powering on for optimum performance.
