Yamaha HTR-5990 Using bi-wire and bi-AMP connections, Conventional connection, Bi-wire connection

Using bi-wire and bi-AMP connections

Some of the speakers commercially available these days have speaker wire connections that allow bi-wiring or bi- amplification to enhance the performance of the speaker system. This unit allows you to make bi-wire and bi-AMP connections to one speaker system. Check if your speakers support bi-wiring or bi-amplification. As these speakers are shipped to you, you will note gold-plated shorting bars or bridges, one connecting the two red input terminals and the other connecting the two black input terminals. Remove these shorting bars or bridges only if you plan to bi-wire or bi-AMP your speakers.

■Conventional connection

If you want to connect your speakers as traditional loudspeakers using the conventional connection method, connect your speakers using the regular left and right speaker wire connections and ignore the second set of terminals.

■Bi-wire connection

The bi-wire connection separates the woofer from the combined midrange and tweeter section. A bi-wire compatible speaker has four binding post terminals. These two sets of terminals allow the speaker to be split into two independent sections. This split connects the mid and high frequency drivers to one set of terminals and the low frequency driver to the other pair.

Notes

•Remove the shorting bars or bridges to separate the LPF (low pass filter) and HPF (high pass filter) crossovers.

•To use the bi-wire connections, press SPEAKERS A on the front panel so that SP A lights up in the front panel display.

■Bi-AMP connection

The bi-AMP connection uses two amplifiers for both speakers. One amplifier is connected to the woofer section of a loudspeaker while the other is connected to the combined mid and tweeter section. With this arrangement each amplifier operates over a restricted frequency range. This restricted range presents each amplifier with a much simpler job and each amplifier is less likely to influence the sound in some way. The internal crossover of the speaker consists of a LPF (low pass filter) and a HPF (high pass filter). As its name implies, the LPF passes frequencies below a cutoff and rejects frequencies above the cutoff frequency. Likewise, the HPF passes frequencies above its cutoff.

Notes

•Remove the shorting bars or bridges to separate the LPF (low pass filter) and HPF (high pass filter) crossovers.

•To activate the bi-AMP connections, set BI-AMP to ON in ADVANCED SETUP (see page 89).

•To make the bi-AMP connections, use the FRONT and SURROUND BACK terminals as shown below.
