Using Mono for Smoother Coverage
In large or irregularly shaped rooms, you may find that the main listening area may be closer to one of the speakers. If the speakers in the room are connected to a stereo amplifier you will only hear half the music. The
•Large rooms with many seating areas and/or many pairs of speakers.
•Irregularly shaped rooms.
•Bathrooms with one speaker over the tub and one speaker over the sink(s).
•Hallways or passageways (including those with multiple speakers).
•Small rooms, such as
Bridging Channels for Areas
that Require More Volume and Power
There are several situations where bridging is an excellent way to improve the sound. There are also applications where bridging would seem to be appropriate but is not recommended. Bridging channels increases the power output to 80 watts per channel at 8 ohms.
These are some of the most common DOs and DON’Ts:
1.Outdoors (DO) — Sound dissipates faster outside than it does in a room where the walls enclose the sound and reflect it back to the listener. A pair of speakers playing into a large patio or yard will greatly benefit from bridging four channels into two 80 watt channels.
2.Surround Sound Systems (DO) — The dynamic demands for the center channel are much greater than the left, right or surround channels. This is an excellent application for two channels to be bridged into one 80 watt channel.
3.More than one pair of 8 ohm speakers (DON’T) — In a large room or a long hallway, often the best way to get good background music is to install
multiple pairs of speakers. You will actually deliver more power to two pairs of 8 ohm speakers by using two unbridged amplifier channels than you would if you bridged four amplifier channels into two and connected the two pairs of speakers in parallel.
