being separated by a 2-second pause. Each sequence provides tones for check- ing frequency response, as well as left/ right channel identifiers. Configuration DIP switch 5 is used to select whether the basic or advanced multi-tone sequence will be generated. Refer to Appendices A-1 and A-2 for detailed descriptions of the multi-tone sequences.

Multiple Play Functions

When more than one play button is se- lected, a different set of rules apply. If the voice button is selected, along with the single tone and/or multi-tone button(s), the voice sequence of L+R, L ONLY, and

RONLY will play once, a 2-second pause will occur, and then the next selected function will become active.

If the single tone button has been se- lected, along with the voice and/or multi- tone button(s), a 400Hz or 1kHz tone will be generated for 15 seconds, a 2-second pause will occur, and then the next func- tion will become active.

If the multi-tone button has been selected, along with the voice and/or single tone button(s), one complete basic or ad- vanced multi-tone sequence will be gener- ated, and then, after a 2-second pause, the next function will become active. To know which function is active is simply

a matter of observing the play LED indicators.

AUX and Main Master Level Controls

Two controls are used to set the overall level of the AUX audio bus. The inner knob controls the level of the left channel; the outer knob controls the right channel. On the front panel, note the small arrow graphic symbol and the letter “U,” located at the “1-o’clock” rotation position. This indicates the approximate setting for the level controls to give unity gain, and is the position where the controls should nor- mally be set.
