PRODUCT DESCRIPTION – The SHUTTLE
®
MAX 12.2 bass amplier has been designed with our unique ultra light
unied design process, yielding a 1200 watt (2 x 600 watt) professional high powered tour-class bass guitar amplier
weighing only 6.75 lbs! The SHUTTLE
®
MAX 12.2 is the 2nd generation of Genz Benz SHUTTLE
®
MAX ampliers
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 amplier. 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 amplier that achieves a more 3
dimensional tone and feel, like a tube amplier power section, without the anemic atness other amplier 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 lters 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 amplier 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.
