The record output may be turned off (see Customizing Your Nº383

 

 

 

for more information.) The record outputs will also be shut off

 

 

 

when the preamplifier is placed into standby.

AC mains receptacle

 

 

 

This IEC-standard AC mains receptacle is used with the remov-

 

 

 

able AC power cord to supply the Nº383 with power.

 

 

 

 

Warning!

 

 

Prior to connection to the AC mains, please check the

 

 

 

voltage label on the rear panel of the Nº383 to ensure

 

 

 

that your unit conforms to the power supply in your

 

 

 

area.

 

 

 

 

 

 

 

Following the guidelines in the Quick Start section of this manual,

 

 

 

connect the power cord to this receptacle and the AC mains outlet

 

 

 

in the wall.

 

 

 

When power is first applied to the Nº383, it will run through an

 

 

 

automatic initialization sequence which displays a software identi-

 

 

 

fication code, and then enter standby.

For optimal sonic performance and longevity, the Nº383 is de-

 

 

 

 

 

 

signed to remain powered at all times (the standby button merely

 

 

 

mutes the preamplifier’s outputs and turns off the display). There

 

 

 

is an initial break-in period of at least 25-50 hours before the

 

 

 

Nº383 achieves optimum performance.

 

 

 

 

Note:

 

 

If AC mains power to the Nº383 is interrupted, the

 

 

 

main output will be muted. When power is restored,

 

 

 

the initialization sequence described above will restore

 

 

 

the preamplifier to standby.

 

 

 

 

 

 

 

We recommend you allow the circuitry within your various sys-

 

 

 

tem components to stabilize by leaving it in standby for 1 to 2

 

 

 

minutes before use after a power outage.
