CHAPTER 2

Biamping

If your speakers can be biamped, the Cinema Grand AmpliÞer can be conÞgured to provide a very powerful stereo system.

Inputs

Tweeter

Woofer

A speaker which can be biamped or biwired will have two sets of binding posts. Sometimes these posts are joined with shorting links for normal operation.

Make sure that any links are removed when you want to biamp or biwire the speak- ers. If not, this may cause damage to the ampliÞer.

Each speaker can be driven by two ampliÞer channels, one to drive the woofer and one for the upper range. You will need to use four ampliÞer channels to run two speakers.

If you use the Cinema Grand Ampli- Þer for biamping, then a total of three speakers can be connected. You will need an extra two channel ampliÞer if you want to run the surround speak- ers in a Home Theater system.

The following connections are shown in the diagram on the next page.

Output connections

•Connect the ampliÞer’s right rear output to the right speak- er’s woofer input terminals and connect the ampliÞer’s right front current source output to the right speaker’s upper range input terminals. If you prefer, you could use the right front voltage source instead.

•Connect the ampliÞer’s left rear output to the left speaker’s woofer input terminals and connect the ampliÞer’s left front current source output to the left speaker’s upper range in- put terminals. If you prefer, you could use the left front voltage source instead.

Input connections

Each ampliÞer channel has two RCA inputs which are connected together internally.

•Connect the preamp stereo output to the front channel RCA jacks. Then install short interconnects from the other unused front RCA jacks across to the rear channel RCA jacks. In this way, the front and rear ampliÞer channels are fed with the same signal from your preamp.

•Note: you cannot use XLR cables in, with RCA out, or RCA in with XLR out. There is no direct internal connection between the RCA and XLR inputs.
