CoNNECToR PANEL oN THE HECo ALEVA GT LoUDSPEAKERS / BI-WIRING AND BI-AMPING
Heco Aleva GT 1002, 602, 402:
The connector panels on the Aleva GT speakers are equipped with 5 terminal screws, enabling bi-wiring/
bi-amping in addition to conventional connection to an amplifier. The upper terminals are connected to
the treble and mid-treble side of the crossover and the lower terminals to the bass side. An additional
connector terminal enables a 2dB treble boost option.
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.
For conventional connections, metal bridges are installed as standard to make the +2dB treble adjustment
active. The bridge can be switched to the linear setting by unscrewing the corresponding terminals. (Fig.4)
The terminals have to be removed for bi-wiring and bi-amping mode. Fig. 5 and fig. 6 show the connection
to the amplifier(s).
The right treble setting depends on the room, the positioning of the speakers and, of course, personal
taste. The +2dB setting is recommended for rooms with heavy upholstered furniture and curtains, for
example, which have a muffling effect.

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 ALEVA GT 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. 7a), bi-wiring (Fig. 7b) and bi-amping (Fig. 7c).
HECo ALEVA GT CENTER 32
The ALEVA GT CENTER 32 loudspeaker visually and acoustically ideally matches the other ALEVA GT
models. The loudspeaker is placed immediately underneath the television set. Otherwise please adhere
to the general recommendations outlined in the previous chapters.
HECo ALEVA GT SUB 322A
The ALEVA GT SUB 322A active subwoofer visually and acoustically ideally matches the other
loudspeakers in the ALEVA GT series. Please refer to the separate operating instructions supplied with
this product.

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!
