SPM-4250
•This 3-way amp allows you to power your left and right main speakers and your
subwoofers, with no crossover necessary, all from one 2U rack chassis. The 3WA-
1700 easily powers four 8Ω speakers for the stereo mains and two 8Ω subwoofers
with 450W of power per channel plus a whopping 800W for the subs! A perfect amp
for DJ’s, traveling bands, and small clubs. •Power Output Ch 1 & 2: 2 x 450W @ 4Ω,
Subwoofer: 800W @ 4Ω •Selectable internal Low Pass Filter can be adjusted from
50Hz to 250Hz to maximize the tight punch of your subs •Filter / Source switch – to
enable the internal low-pass filter and use the left and right input signals for the sub-
woofer – or to disable the internal filter to either use an external active crossover or
use the Sub channel to pass full-range signals for monitor feeds or sound reinforce-
ment •Selectable Low Cut Filter to minimize muddy bass and stage rumble •Bal-
anced XLR and ¼” TRS inputs; binding post (banana plug) outputs, detent volume
controls for each channel •Full safety/reliability features: 4 variable speed fans for ul-
timate cooling; noise-free on-off; built-in DC offset; independent DC and thermal
overload protection on each channel; short circuit and speaker protection •Power
ON, Signal, Clipping, and Protect LED indicators for each channel •Roadworthy,
rugged double rack space (2U) housing •115 (60Hz) IEC power cord connector and
3AG fuse holder
