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).

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

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!
