A Digital Output jack passesyour digital source'sdata stream directly to a digital recorder like a Mini Disc, DA T, DCC or CD.R. This is an RCA type connector; use only digital quality cable.

AC Power

Your DIAC-1500 hasan IEC standarddetachablepower cord which hasbeenspeciallyselectedfor its contribution to the soundquality of this unit. Try to connectonly this cord directly to a nearby AC wall outlet andavoid extensioncordsor connectionto accessoryoutletson your preamp.

Sampling Frequency LEDs

Your DIAC-1500 will recognizethedigital signalof whatevertype of digital sourceyou connect andwill switch to the correctsamplingtateautomatically. The 44.1 kHz samplingtateis standard for compactdiscs. 32 kHz is for digital broadcast;48kHz is for DA T.

Error/Data LED

In casethereis an interuption of datafrom the digital sourceor a malfunction of thedigital source or connection,the ErrorIDataLED will illuminate. This showsyou that your DIAC-1500 is not receivingcorrectdigital datato processandconvertto analog. In this case,a muting circuit will
