Results of unrealistic tests

You may elect not to use either Record Output with this particular device, as may be the case if you have several devices in your system that are capable of recording. In this case, leave the display on “RECD NONE” and move to Step 6.

You may also select either Record Output 1 or 2 to be associated with this particular input. To do so, press the input button repeatedly until you see your choice of OUT1 or OUT2 in the display. (OUT1 is given as an example on the next page.)

Save your choice in non-volatile memory by pressing and holding the Mode button until the display reads NEW DATA, as below.

Note: The Nº38 Preamplifier has been optimized to yield optimum sonic performance under normal, real-world operating conditions. This approach involves no disadvantage when the unit is used as designed.

Unrealistic tests such as listening at full gain to an unterminated input which has been associated with an unterminated record output may result in some small amount of noise at the main output which does not occur when the Nº38 is used correctly. Moreover, even under these unrealistic test conditions, any resulting noise is small and poses no danger.

Rather than compromise the sonic performance of the preamplifier in an effort to eliminate even the remote possibility of this noise being detected, the set-up procedure outlined above for programming input aliases was designed to make it virtually impossible to create a condition under which any such noise can be heard. We recommend using the input alias NOT USED for all unused inputs.
