from the mixer, this approach would tend to pick up excess noise. Best practice would be to run a "hot" signal
from the mixer down the cable to the SP®4P, and then turn the SP®4P Gain control up only as much as necessary
to reach full desired output. With this approach, it is necessary to verify the mixer output is not clipping.
Disconnecting AC Power to the SP™4P
We recommend that the Power switch (1) be used to turn the unit off first, and then the AC power cord can be
removed, this minimizes stress to the power amplifiers and the transducers from turn-off transients. The power
switch has an arc suppression capacitor to help during turn-off, and tends to make a clean disconnect from the
AC power, while the power cord IEC connector can make intermittent contact before finally becoming fully
disconnected, e.g., as when wiggling the cord.
