Page 9: Mains Power Connection
Switching between mains voltages has to done by an authorised Stage Accompany service centre. Connecting to the wrong voltage is dangerous and may damage the amplifier. Always ensure that you use a correctly grounded power supply. - Page 10 DS20 USER MANUAL stage accompany This will prevent unnecessary power loss in the mains cables. If circumstances do not allow this, it is advisable to connect the adapter block directly to the power supply using a short cable and then connect the individual DS20s to it using longer leads. Although this method is not ideal, it does limit power loss as much as possible.

DS20 USER MANUAL stage accompany Loudspeaker Connections The DS20 has 4 output terminals per channel instead of 2. The speakon connector is wired as follows: Pin 1+ = “hot” or Signal+ Pin 1- = “cold” or Signal- Pin 2+ = “ hot” or Signal+ NEUTRIK Pin 2- = “... - Page 14 DS20 USER MANUAL stage accompany If you don’t want to use the DDC feature at all, the DDC and the signal leads should be linked at the amplifier output in the speakon connector (see figure 3-4). The DDC terminals can also be left unconnected but then the performance will be less.
- Page 15 DS20 USER MANUAL stage accompany When more speakers are going to be connected to one amplifier, split the output and DDC leads as soon as possible behind the output terminals of the DS20 (see figure 3-7 on this and figure 3-8 on the next page).
