User's Manual

Overview

The Cinema Ribbon Trios are high performance speakers that are speciﬁ - cally designed to work with your ﬂ at panel display. Sharing technology with the rest of the Cinema Ribbon line, years of research and decades of experience have gone into these amazing loudspeakers.

The Cabinet

The Cinema Ribbon Trios feature a carefully designed cabinet that stems from years of research into how the box affects the sound of the loudspeaker. The specialized facets of the Cinema Ribbon Trios result in a loudspeaker that is free of unwanted sonic bounces.

The Ribbon - A Legacy Reﬁ ned

The ribbon in this loudspeaker is a remarkable piece of engineering, because it has the output capability, purity, and low distortion of a 6-foot tall ribbon - in fact, it is derived from Bob Carver’s award-winning Amazing Loudspeaker from the late 1970s! The sound from the CRS-3 ribbon is deliberately focused in the forward direction, with very little sound going up or down - reducing reﬂ ections off the ceiling and ﬂ oor, that disturb the sense of space and imaging. The CRS-3C features an integrated “acoustic lens,” that disperses the signal for center channel applications.

The Woofers - A Legacy Reﬁ ned

Sunﬁ re created the category of small-box, high-power subwoofers more than a decade ago with the original True Subwoofer. This design relies on high-pressure, “High Back-emf” technology that provides very high bass output from a very small box. When migrating this subwoofer technology to the midrange and high frequencies on the Cinema Ribbon Trios, you get the same advantages: high output, small size, high efﬁ ciency, and years of trouble-free operation.

Conclusion

The Cinema Ribbon Trios are the most powerful speakers available today for ﬂ at panel display applications. Combine this with their specially designed cabinets and highefﬁ ciency ribbons, and you have the ultimate home theater experience. Are you ready?

Happy listening!

1. Boundary Compensation Switch

This switch compensates for bass and

mid-bass loading that occurs when a

loudspeaker is wall-mounted, com-

pared to when it is away from a wall.

Switch it to the left if your loudspeaker

is close to a wall or other large objects

that may cause reﬂ ections. Switch it to

the right if the loudspeaker is placed

more out into the room, such as when

on a stand. Experiment with the switch

to ﬁ nd the position that suits your

preference.

2. Ribbon Binding Posts

3. Woofer Binding Posts

The loudspeakers have two sets of

bind ing posts that are joined with

bridge clips (4) for normal operation.

With the bridge clips in place, you can

connect your ampliﬁ er outputs to either

positive/negative pair of binding posts.

Always use high quality connections

and speaker wires, and make sure

there are no loose ﬁ ttings or stray wire

strands. They will accept bare wire,

pins, banana plugs and spade connec-

tions.

Connect the positive speaker-level output of your power ampliﬁ er or receiver to a positive (red) input of the loudspeaker. Connect the negative speaker-level output of your power ampliﬁ er or receiver to a negative (black) input of the loudspeaker.

Make sure that the positive and negative connections do not touch, or this may damage your power ampliﬁ er.

Tighten all four binding posts to make sure the bridge clips are making a good contact.

4. Bridge Clips

From the factory, the two positive binding posts are electrically joined together with a bridge clip, as are the two negative posts. Leave the clips in place, unless you are considering biwiring or biamping.

If the bridge clips are removed, the loudspeaker can be biwired or biamped. The ribbon posts (2) are then used for connection of speaker-level power to the ribbon section. The woofer posts (3) are for connection of speakerlevel power to the woofer section. (See the next two pages for more details.)
