The UNI-PRE is a new generation bass preamp system from East UK. It’s a brand new modular design that sets new
standards with unique features. Designed to fit virtually any bass with rear cavity electronics, the UNI-PRE is available in 3,
4 or 5 knob configurations as either 2 or 3 band EQ. Although it is designed as a complete system, the Volume/ Blend and
EQ modules are also available individually for stand-alone use.
Its main components are the Volume/Blend and EQ modules. The Volume/Blend module has totally independent dual active
and passive signal paths. In other words two volumes and two blends are controlled simultaneously with a conventional
knob set, using custom pots. The EQ module allows internal voicing adjustment for the treble as well as the lower and upper
bass frequencies for the bass control. This is to allow finely tuned focus on the most crucial parts of the bass spectrum.
Modular construction makes for easy installation, with simple plug connections between modules. External wiring, such as
pickups and power, are simply connected using screw terminals.
Summary of features:
•
Totally independent active and passive signal paths guarantee completely smooth blend when set to active.
• Custom designed pots allow optimal placement of all controls within active and passive signal paths.
• Class A FET input stages for great sound quality, with two gain trim preset adjusters, one for each pickup.
• Operational response of Bass Control can be set internally at both the lower and upper end of the bass spectrum.
• Treble Control with internally adjustable frequency voicing, plus Bright as a pull switch.
• Mid Control with Frequency Sweep.
• Overall response can be set as flat or with pre-shaper contour which adds some warmth and sheen.
• Modular concept allows for easy installation and replacement of parts, all with pluggable inter-connections.
• Screw terminals are used for all external connections such as pickups, power and grounding for easy installation.
