You are now installing a component capable of dramatically improving the performance of almost any home theater system. designed and manufactured theater amplifier from AudioControl that will provide years of trouble-free enjoyment for your home theater system. [. . . ] The Savoy is designed to increase the strength of the signal it is provided and direct it out to the speakers. If you provide a poor signal, the Savoy may only make it a louder poor signal. When running cables further than 20 feet, it is wise to use Balanced XLR audio interconnect cables (provided your source unit has Balanced XLR outputs). Balanced XLR cables provide better noise rejection than unbalanced RCA cables due to the way they carry the signal. If your source unit does not have Balanced XLR outputs (you won't have this problem if you're using a Maestro M2 pre-amplifier), it would be worthwhile to consider using the AudioControl BLD-10 and BLR-10 (see Appendix). These pieces allow you to transform an unbalanced RCA signal to a Balanced XLR signal that can be sent up to 1000' over standard Cat-5 cable. Connecting the Speakers It may sound as though we are repeating ourselves, but the process for connecting the speakers is very similar to connecting the audio (discussed previously), and many of the same steps should be followed. Turn off ALL components before making any connections. When making connections, label the cables to more easily distinguish each channel and decrease the chances of improperly wiring your system. This will not only make it easier on you if you need to make an adjustment, but also in the case that someone else works on the system after you. Use quality speaker cables, preferably shielded, as signal loss and interference cannot be overcome by the Savoy's many features. The Savoy is designed to increase the strength of the signal it is provided and direct it out to the speakers. Signal loss or interference picked-up between the Savoy and the speakers cannot be compensated for in the Savoy.

In Figure 5, the table shows the impact wire resistance will have, even in shorter lengths. A common practice among system designers is the 5% rule. This rule states that the wire resistance should not exceed 5% of the speaker's minimum resistance. This keeps the volume level change due to line losses to less than 0. 5dB. As an example, on an 8 ohm speaker, the wire resistance should be less than 0. 4 ohms (5% x 8 = 0. 4). Use Figure 5 to determine the proper wire gauge for your application. Select the proper speaker cable connectors to connect your speakers to the Savoy. The 5-way binding posts on the Savoy will allow you to use a number of cable connectors including pin, fork, banana plugs, or even bare wire (see diagram). As in any relationship, a deep and solid connection will join your speakers and Savoy amplifier "until death do them part!" 5. Non-uniform speaker polarity within a speaker system will drastically effect the sound. [. . . ] AudioControl will match whatever shipping method you choose to send in the unit. If you send it overnight, AudioControl will return it overnight. If you send it on the back of a gypsy's camel, well. . . AudioControl will probably choose a different method to return the unit to you.
