HECO VICTA PRIME 702, 602, 502, 302 – BI-WIRING AND BI-AMPING
Bi-wiring means using separate cables to carry the high and low audio frequencies. Bi-amping takes this
idea one step further and uses separate power amplifiers as well as separate cables for high and low
frequencies. Bi-amping in particular produces an additional improvement in sound reproduction quality.
The special connection terminals of the VICTA PRIME loudspeakers support both conventional connection
and operation in bi-wiring and bi-amping modes. There are four screw terminals on each speaker. The
top pair are for the tweeter (high frequencies), the lower pair for the woofer (low frequencies). The
factory-installed metal strips connecting the positive and negative terminals are for conventional 2-wire
connection and must be removed for bi-wiring and bi-amping operation. The pictures below show the
correct set-up for conventional operation (Fig. 4a), bi-wiring (Fig. 4b) and bi-amping (Fig. 4c).
HECO VICTA PRIME CENTER 102
The VICTA PRIME CENTER 102 loudspeaker visually and acoustically ideally matches the other VICTA
PRIME models. The loudspeaker is placed immediately underneath the television set. Otherwise please
adhere to the general recommendations outlined in the previous chapters.
HECO VICTA PRIME SUB 252 A
The VICTA PRIME SUB 252 A active subwoofer visually and acoustically ideally matches the other
loudspeakers in the Vica series. Please refer to the separate operating instructions supplied with this
product.
CONNECTING TO AN AV RECEIVER

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls
in the central position – i.e. with “linear” amplifier output. Turning up the bass and treble controls too far
delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the
speaker units!
If the output of your amplifier is significantly higher than the rated power handling capacity of your
speakers extremely high volumes can physically destroy your speakers. This doesn’t actually happen
often but you should be aware that it is possible.
Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium
volumes because weak amplifiers may overload much faster than powerful ones and this causes
measurable and audible distortion, which is extremely dangerous to your loudspeakers.
Always turn the volume down immediately as soon as you hear distortion! If you like listening to loud music
make sure that your amplifier can deliver at least as much power as the speakers’ power-handling rating.
THE SOUND YOU CAN’T HEAR...
Amplifiers, tuners and CD players can all produce inaudible high-frequency signals – and this doesn’t
only apply to cheap products. If your tweeters fail at low or medium volumes you should have a qualified
technician check your system components for dangerous inaudible signals.
