XLR Inputs, Current Source Fuses, AC Line fuse

4. XLR Inputs

If your preampliÞer has XLR outputs, connect them to these XLR inputs. Use them instead of the RCA inputs because balanced connections offer superior noise rejection.

The female XLR inputs are wired as follows:

Pin 1 is ground

Pin 2 is positive (hot)

Pin 3 is negative (cold)

Balanced connections pass the input signal along two conductors. If there is any external noise and inter- ference passing into the audio lines, both conductors will receive the same amount of noise. This noise is then rejected in the balanced input stage of the Cinema Grand AmpliÞer.

5.Current Source Outputs and:

6.Voltage Source Outputs

The front left, front right, and center channels each have a Voltage Source output and a Current Source output.

The Voltage Source output has a source impedance of approximately zero ohms. The Current Source has

asource impedance of approximately one ohm. The left rear and right rear channels have Voltage Source out- puts only.

The top post of each binding post pair is the positive output, and con- nects to the positive (red) post of your speaker. The bottom post of each pair is the negative, and connects to the negative (black) post of your speaker. The posts can accept bare wire, spade terminals, and dual or single banana connectors.

CHAPTER 1

NOTE: The Current Source output is a Voltage Source modiÞed to yield a Current Source impedance of one ohm. This corresponds approximately to a vacuum tube ampliÞer output im- pedance and constitutes the dominant factor in the soundstage delivery of classic vacuum tube power ampliÞers.

7. Current Source Fuses

Each Current Source output has an in-line fuse to protect your speakers. If one ever opens, there will be no out- put to that speaker. Turn off the power if you ever have to change a fuse.

8. IEC connector

The ampliÞer comes with a detach- able Linecord which attaches here. Make sure it is Þrmly pushed in place. Connect the other end to an AC outlet which is properly conÞgured for the type of plug and has the correct volt- age for your model.

9. AC Line fuse

If this fuse fails, replace it with the exact same type and current rating.

According to your musical taste, you may select the Current Source for driving electrostatic, planar magnetic or ribbon speakers. Select the Volt- age Source for driving subwoofers. For cone based systems, use either. For a biwired system, use the Current Source for midrange and treble driv- ers, and use the Voltage Source for the subwoofer(s). These are sugges- tions only. By all means, please feel free to experiment with other wiring options.

Note: Always unplug the power cord from your AC outlet before removing the fuse.

With a ßat ended screwdriver, push the fuse carrier in slightly and turn it counter-clockwise to release.
