Application of DNM speaker cable termination networks Connecting the DNM series/parallel ZRTN and the parallel HFTN to a system with an unbalanced (ground referenced) amplifier The two stages of upgrade to:1) the DNM Zero Reflection Termination Network (ZRTN) 2) the DNM High Frequency Termination Network (HFTN) Stage 1: fit two DNM ZRTN’s, connected as shown (labelled 1 left channel & 2 right channel) at the amplifier end of the speaker cable. Stage 2: optionally for a further upgrade, fit two DNM speaker cable HFTN’s (labelled 3 left channel & 4 right channel) at the speaker end of the speaker cable.

NB. two ZRTN s are needed for each channel for use on an amplifier with balanced outputs. Important note: the two negative terminals of the ZRTN pair must be link** connected as shown. Stage 1: fit four DNM ZRTN s arranged in two pairs, connected as shown (labelled 1 & 2 left channel, 3 & 4 right channel) at the amplifier end of the speaker cable. Stage 2: optionally for a further upgrade, fit two DNM speaker cable HFTN s (labelled 5 left channel and 6 right channel) at the speaker end of the speaker cables. left channel output link** 1 DNM ZRTN DNM ZRTN 2 right channel output link** 3 DNM ZRTN DNM ZRTN 4 DNM HFTN 5 speaker cable left channel speaker cable right channel DNM HFTN 6 Balanced AMPLIFIER Produced by DNM Design 11th March 2014 left channel speaker right channel speaker
