This Snapper can be driven fully balanced all the way through via the XLR inputs. If you have balanced outputs on your preamplifier, this amplifier is the first Manley design to really let you take advantage of your XLR's without additional balancing input circuitry or input transformers. Very cleverly, the unbalanced RCA's can alternatively be used in this special topology with equally impressive results.\u003cbr\u003e\u003cbr\u003eThe Snapper will crank out 100 watts at 10 cycles all day long and a full 110 watts from about 15Hz all the way up to 40KHz. Don't let frequency response specs fool you when people give you amazing bandwidth measured at... oh, five puny watts. We're talking full power bandwidth here! Continuous duty. Real muscle. \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-weight: bold; text-decoration: underline;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"spec\"\u003e100 Watt ultra-linear EL-34 output stage is tolerant of a wider variety of output load conditions than pure pentode.\u003c\/li\u003e\n\u003cli class=\"spec\"\u003ePrecise and balanced signal path from input to output.
