The Tech 21 SansAmp PSA-1.1 is an upgraded version of the popular Tech 21 SansAmp PSA-1. While the 100% analog signal path and functionality remain the same, the redesign made it possible to include a few new convenient features: an on/off switch on the front panel, more program locations (there are now 128), a master volume control, an XLR ground lift switch, phantom power MIDI input, and a dedicated headphone output.
Via MIDI, you can load and off-load presets, map program locations, and select MIDI channels (including Omni Mode). Remote program changes can also be made via MIDI (including Tech 21’s own equally player-friendly MIDI Mouse footcontroller). Other features include dual 1/4” and XLR outputs for stereo processing, either of which can be set at line or instrument level, and used simultaneously. The non-glare, 3-digit LED display is readable from any angle, in daylight or darkness.
Considered a staple in professional recording studios, the SansAmp PSA has been used on major releases and worldwide tours for multiple applications and instruments, including horns, vocals and drums. Players, engineers and producers alike find the SansAmp PSA very simple to operate. To program, you just tweak the knobs and save. Parameters are adjusted in real time with traditional analog potentiometers. The digital memory stores the positions of the pots. With 256 incremental steps, each rotary control increases and decreases in a smooth linear fashion.
The exceptionally versatile SansAmp PSA-1.1 offers 49 factory presets of the most recognized vintage and modern tube amp sounds for guitar and bass, and 77 user-definable locations. A Universal Output Section enables the signal to be compatible with full range systems as well as guitar/bass speaker cabinets. With the SansAmp PSA-1.1, you can record direct to tape, as well as warm up existing tracks in mixdowns. For live applications, it can be used as a pre-amp, “monster direct box” to P.A. system, and as an outboard processor.
