Fine Tuning; Troubleshooting Guide - Paradigm Reference OM-560 Manual

Other Connection Options
DO NOT attempt to bi-wire or bi-amplify unless you
have removed the jumper bars.
Standard Connection for Speakers with Two
Input Terminals
(Fig. 3)
Leave the jumper bars attached and connect using either set of input terminals
following the instructions given under "Standard Connection" on page 5.
Bi-wiring and Bi-amping
Removing the jumper bars gives separate access to each frequency
section of the speaker, which then allows for two optional connection
configurations:
1) Bi-wire Connection
(Fig. 4)
Bi-wiring can improve clarity and openness, with less grain and more
solidity to the bass. Two cables are required for each speaker that you bi-wire.
2) Bi-amp Connection
(Fig. 5)
To bi-amplify, two power amplifiers are required. Connection can be either
vertical or horizontal. Connect your speakers to one amplifier at a time.

FINE TUNING

Once you have your speakers positioned in the room, and have set speaker
distances and speaker level calibration with your Processor or A/V
Receiver, it's time for a little fine tuning. Since Paradigm
speakers are designed to provide exceptional high-end performance in a
variety of room settings, fine tuning is simply a matter of making slight
adjustments to speaker placement in the room. To fine tune your front
speakers, center channel, and subwoofer refer to the Owners Manual
included with those speakers.

TROUBLESHOOTING GUIDE

PROBLEM
Make sure receiver, preamp or amplifier is plugged in and turned on. Check power outlet at the wall is working.
No Sound
Are headphones plugged in, or is system on Mute?
Re-check all connections.
Check your balance control or VC-150 Volume Control (if using).
No Sound from One or
Check that all power cords are properly plugged in and functioning.
More Speakers
Swap a non-working speaker with one that works to determine if the problem is with the speaker or something else (i.e. wiring, amplifier).
Lack of Bass or
One or more speakers may be connected out of phase (their polarity is reversed).
Dislocated Image
Re-check to ensure that each speaker's cable is connected with correct polarity: red (+) to red (+) and black (-) to black (-).

IMPORTANT! When bi-amping, always use amplifiers with identical
gain. If uniform gain is not maintained, the speaker system's frequency
balance will be incorrect when horizontally bi-amped; and when vertically
bi-amped the speaker-to-speaker balance will be incorrect. To prevent
problems, use identical amplifiers (Brand and Model), in identical operating
modes (single channel or bridged).
Passive bi-amping offers a dramatic improvement in clarity, openness and
detail, with much better bass solidity and definition. The presentation of
music and movie soundtracks is simply more intelligible and transparent.
With passive bi-amping, the speaker's internal passive crossovers remain
connected. An external electronic crossover is not required and cannot be
used (there is no direct electrical access to individual drive units). This
saves expense and setup difficulties. Passive bi-amping optimizes your
speakers to achieve the best possible high-end performance.
Horizontal Bi-amplification (Fig. 5) dedicates one amplifier to your
speakers' mid/low-frequency inputs and another to their high-frequency
inputs. This configuration can maintain better clarity when listening at
loud levels—if low-frequency demands cause amplifier clipping, distortion
will still be kept away from high-frequency drivers.
Vertical Bi-amplification (not shown) dedicates one amplifier to each
speaker. This configuration provides complete channel separation which
optimizes your system's imaging ability.
Fine tuning Surround and Rear speakers is a matter of making adjustments
that may be required for a particular multichannel music or movie program.
® Reference If necessary, adjust your Processor or Audio/Video Receiver levels to
ensure that there is a cohesive overall soundstage.
