Selecting Wattage Taps
The Sx600 is intended to be a high level speaker, so the transformer
taps are set up to produce a full 600 watts at each of the 4 voltages
listed. If necessary, the wattage may be halved by selecting the next
HIGHER voltage tap. NEVER select a tap for a LOWER voltage! (i.e;
Do not use a 70 volt tap in a 100 volt system, etc.) The Sx600PIX is
shipped from the factory pre-wired for 600 watt operation on standard 70
volt lines. To select a higher voltage, remove the 10 mounting screws
around the perimeter of the input panel (See Figure 6). CAUTION: the
transformer alone weighs 18 lb. (8.2 kg.) Be prepared to support this
weight when the screws come out! Carefully tip the panel outward from
the enclosure, taking care not to damage the water gasket or strain any
of the internal connecting wires. Locate the WHITE wire of the input
cord and carefully pull its connector straight back off the 70 volt tab.
Select the desired voltage and push the connector securely onto the
corresponding tab. Do NOT move the black wire, which must stay
connected to COM. Inspect the water gasket for dirt or damage, and
reassemble the panel to the enclosure. Using a permanent marker,
MARK THE NEW VOLTAGE SETTING in the box provided on the
Sx600PIX label.
