Getting Started
The following steps will help you set up the DRM18S quickly.
1. Make all initial connections with the power switches OFF
on all equipment. Make sure the master volume, level and gain
controls are all the way down.
2. Connect the outputs from the mixing console (or other
signal source) to the inputs on the DRM18S, then connect
the high pass outputs from the subwoofer to the inputs
of the loudspeakers.
3. Push the line cord securely into the subwoofer's /
loudspeaker's IEC connectors and plug the other ends into
grounded AC outlets. The subwoofer/loudspeaker may accept
the appropriate voltage as indicated near the IEC connector.
4. Turn the mixer (or other signal source) on.
5. Turn the subwoofer on.
6. Turn the loudspeakers on.
7. Make sure the subwoofer's channel levels are set
to (or near) 0 dB.
8. Make sure the loudspeaker's channel levels are set
to (or near) 0 dB.
9. Start the signal source and raise the mixer's main L/R
fader up to a comfortably loud listening level.
Things to Remember:
• Never listen to loud music for prolonged periods. Please see
the Safety Instructions on page 2 for information on hearing
protection.
• As a general guide, the mixer (or other signal source) should
be turned on first, DRM18S subwoofer next, and loudspeakers
last. As such, the loudspeakers should also be turned off first,
followed by the DRM18S, then the mixer. This will reduce
the possibility of any turn-on or turn-off thumps and other
noises generated by any upstream equipment from coming
out of the speakers.
• Save the shipping boxes and packing materials! You may
need them someday. Besides, the cats will love playing
in them and jumping out at you unexpectedly. Remember
to pretend like you are surprised!
• Save your sales receipt in a safe place.
