JBL GHE 1200V Owners Manual English - Page 5

BI-WIRING CONNECTIONS Fig. 6 & Fig. 7 show in closer detail the hooking up of your speakers to the amplifier(s). Two bi-amplification options are shown in detail: one stereo-amp (from Fig. 4) and two stereo-amp (from Fig. 5). IMPORTANT: 1. The external "strapping bars" which normally connect the GHE's HF and LF terminals MUST BE REMOVED BEFORE BI-WIRING CONNECTIONS ARE MADE (See Fig 8). 2. NEVER CONNECT TWO AMPLIFIER CHANNELS TO THE SAME LOUDSPEAKER WITHOUT FIRST REMOVING THE STRAPPING BARS. Operating two amplifier channels with the GHE strapping bars in place can seriously damage the amplifiers! 3. If your preamplifier has just one set of stereo outputs, you will need to use "Y" cords in the two, three, and four-amp biwire hook-ups. "Y" cords are available from many sources including your JBL dealer. 4. If you have hooked up your GHEs in any of the bi-wire configurations indicated, it is not advisable to use additional speakers, either separately or simultaneously. 5. As with conventional one-amplifier, non-bi-wire conections shown in the "CONNECTIONS" section of this manual, make sure that all speaker cables are the same length and that you maintain the "red-to-red" and "black-to-black" connections between the amps and the speakers.
