Note:
Using separate cables fortreble and bass unitsin a Bi-Wiring configuration reducesintermodulation
effectsand improvesheadroomandclarity. Tobi-wire,youwill needtoinstall twolengthsoftwin core

Unscrew each terminal a few turns and remove the metal straps. Connect the cables between the
amplifierandtheloudspeakersasindicatedaboveandre-tightenalltheterminalssecurely.
Some amplifiers have two pairs of output terminals to facilitate bi-wiring but this is not
essential. The advantages ofbi-wiring are fully retainedif your amplifier hasonly one pair ofoutput
terminalsperchannel(asintheillustration).
Byconnecting eachloudspeaker driveunitto itsowndedicated amplifiertheadvantages ofBi-Wiring
can be extended. If you own two identical stereo power amplifiers, your Crystal speakers may be Bi-
Amped.Forfurtherdetailspleaseconsultyourdealer

Models CR30 and 40are designed tobe floor standing.We suggest thatthey are positionedat least

If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and
indistinct. If the loudspeakers are placed further away from the walls, the inward angle may be
increased by up to 40%, although this may restrict the width of the optimum listening position. The
speakers should ideally be positioned so that the treble units are roughly at ear level to a seated
listener.As personaltaste playsa largerole, experimentwithdifferent configurationsand playa wide
rangeofprogrammesbeforefinalisingthepositionofyourspeakers.
The loudspeaker should bepositioned centrally between the loudspeakersclose to the television and

Conventional loudspeakers should not be operated
within 500mm of a TV screen as the drive unit

Conclusion
ManydigitalAVProcessorsrequireyoutospecifythesizeofspeakersinallchannels.
Always choose 'Small' for the Surround channels and Centre channel whether you are using a
subwooferornot.
Setthe FrontSpeakersto ‘Large’.Set the‘Subwoofer’option on
theprocessorto'Off'or‘No'. TheFrontchannelswillnowreceiveallthesystembass.
:When setto‘Small’ allthesystem basswillgo intothe subwoofer.If
you choose ‘Large’ the Front channel bass will be reproduced from the Front speakers. Bookshelf

Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode (see
instructions suppliedwith your processor). Adjust the level ofeach channel inturn until all channels
arereproducedatequalloudness.
On some programme material the surround channel may seem lower than the front. Do not readjust
thislevel. Youmay, however,needto adjustthe subwooferoutputlevel. Avoidsetting toohigha level

In thecinema theLow FrequencyEffects channelis anextra basschannel withits ownsubwoofer and
not a regular subwoofer channel. In domestic systems the LFE channel typically feeds into the
subwoofer. Where no subwooferis used, the LFE signal is combinedwith Front Channel information.
