• Binding post inputs and shrouded screw terminal outputs for convenient and reliable connection to power amplifiers and speaker systems. • Included heavy-duty rack ears allow the DS70 to be mounted in a standard 19" rack (taking just two rack spaces), making it easy to integrate into any existing system. -

DS70 to speaker transformers and loudspeakers. When using the DS70 in two-zone (bridged) modes of operation, a bridge connection must be physically made between two channel ouputs as silk-screened on the rear panel. See the wiring diagrams on pages 6 and 7 in this manual for more information. -

25.2 (wiring code in the U.S. allows 25.2 volt cabling to be used without conduits), and the DS70 supports all three standards. What’s more, up to four separate lines can be output simultaneously (making for four “zones”)—and they can even be at different voltages. -

9 of this manual for more information). Note that four speakers are being used for purposes of illustration only—any number of speakers (up to the rated wattage of the power amplifier or DS70) can in fact be used in each zone. Note also that the the remaining three channels of the DS70 can be used to provide the same or different output voltages. -
Page 7: Two-Zone 70V (Bridged)
The illustration below shows the wiring for two channels of a DS70 being used in Bridged 70 volt mode. Since the two input channels are bridged, a signal of up to 240 watts (into 8 ohms) can be received from the power amplifier. In this kind of setup, the output level controls of the power amplifier can be used to control the volumes of each of the two zones. -

Four-Zone 25.2V (Unbridged) Wiring The illustration below shows the wiring for a single channel of a DS70 being used in 25.2 volt mode. In this kind of setup, the output level controls of the power amplifier can be used to control the volumes of each of the four zones. For volume control of each of the speakers within a zone, optional autotransformers can be used (see Appendix A on page 9 of this manual for more information). -
