We also recommend that you carefully select the gauge
and length of the speaker wire, as these two variables will
effect the speaker impedance load presented to the Savoy
amplifier. In Figure 5, the table shows the impact wire re-
sistance 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 appli-
cation.
4. 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 con-
nectors 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 ampli-
fier “until death do them part!”
5. Non-uniform speaker polarity within a speaker system
will drastically effect the sound. Properly connecting the
positive (+) and negative (-) terminals of the Savoy to
the correlating input on the speaker will ensure correct
polarity among all the speakers. This is accomplished by
verifying the markings on the speaker wire (they are often
color-coded, labeled on the wire jacket, or distinguished
by a ribbing on the wire jacket) and remaining consistent
throughout the system.
Your Savoy amplifier is now completely installed, and
power can be supplied once the system is fully operational.
