PRODUCT DESCRIPTION – The SHUTTLE
unified design process, yielding a 1200 watt (2 x 600 watt) professional high powered tour-class bass guitar amplifier
weighing only 6.75 lbs! The SHUTTLE
which now incorporates our new 3-Dimensional Power Management circuitry. Our proprietary 3DPM™ technology
insures greater and more solid sounding output while retaining the feel and playability of a more traditional tube
based power amplifier. When driving the power amp hard, the player can feel increased heft and girth of the
individual notes, while maintaining dynamics and articulation. The result is an amplifier that achieves a more 3
dimensional tone and feel, like a tube amplifier power section, without the anemic flatness other amplifier designs
can exhibit. This compact design blends the best of analog and digital platforms to produce the ultimate in warmth,
punch and power.
®
The SHUTTLE
MAX 12.2 is equipped with a ¼" unbalanced instrument input; input stage clip detector; mute
switch with LED indicator; FET and 12AX7 tube preamps each with high/low gain stage settings and 4 band active
equalization with 2 sweepable midrange bands; 3 switched SIGNAL SHAPE filters with level adjustments; master
volume; proprietary 3DPM™ technology; tuner out; aux input; 3 effects loops; balanced direct output with ground lift,
pre or post EQ, and mic/line switches; headphone output; 2 Neutrik NL-4 Speakon™ speaker jacks; and a 5-button
footswitch.
The power amp design is a powerful, light weight Class D design and is supported by a state-of-the-art high
frequency Switch Mode Power Supply (SMPS), which does away with the weight of a traditional power transformer.
®
The SHUTTLE
MAX 12.2 uses two 600 watt amplifier modules, both driving full output power into 4 ohms speaker
loads—1200 watts total output. The power supply is usable from 100-240 volts, lending itself well to international
touring players.
