Surround Back Speakers
The DMC-1 has two extra outputs for surround back speakers. These create a wonderful
sense of realism in surround effects during playback of Dolby Digital EX, Dolby Pro Logic IIx,
and DTS ES.
The DMC-1 can be configured for one or two surround back speakers. Ideally, all the surround
speakers should be of the same make and model, and fitted at similar heights to produce a
smooth continuous sound field. If you are connecting one surround back speaker, connect its
amplifier input to the DMC-1 LEFT CHANNEL SURROUND BACK output. Place the speaker
behind your listening position.
Subwoofer Location
The DMC-1 has identical output connections for up to three subwoofers, in addition to a
fourth, balanced sub output.
A subwoofer typically sounds best in a corner with at
least 5 feet of wall to either side. Due to the short wave-
lengths of high-frequency sounds, they don’t interact
strongly with the size and shape of a room. Lower fre-
quencies long wavelengths that can cause “Standing
wave” problems. Placing the subwoofer in a corner usu-
ally creates the best possible situation for the sound to
interact with the room, allowing even distribution of the
bass frequencies. Often the corner that offers nearby
placement to the front speakers may yield the best re-
sults, but you should try several locations before settling
on just one.
The best location for a single subwoofer can be found
by playing a couple of different low frequency test tones
(or some music with heavy sustained bass passages) and proceeding with the following easy
1-2-3 process:
1. Place the subwoofer right on the seat of your couch or listening chair.
2. You can then either run the calibration (noise) signal through it, or simply plug the analog
outputs of a CD player directly into your subwoofer’s low-level inputs. Turn down the subwoofer’s
volume level before turning on the CD, then play the test tones or some music with heavy
sustained bass passages.
3. Walk around the room, standing in all the positions where you might be able to place the
subwoofer. Again, this is usually near the corners of the room. Try locations fairly close to the
front speakers.
