The TranZformer LX is a multifunction pedal that is designed to easily and affordably bring the world-famous analog sound of API to your bass
Offering the user an unsurpassed level of sonic control, the TranZformer LX combines an API 525 feedback-type compressor with a bass-optimized 3 band equalizer, both independently in/out switchable. The unit also features phase invert switches on each output, ground lift, clip indicator and transformer output. Like all API products, the TranZformer LX is built to API's exacting standards and remains true to the design philosophy that has made API the leader in professional analog gear for nearly 50 years.
Traditional fully discrete API circuit design
Variable Compressor with in/out switching
3-Band +/- 15dB Equalizer with in/out switching
Input Gain control with +30dB of gain
Clip LED indicating Input or Output overloading
Balanced and Unbalanced Output Phase reverse
Balanced Output Ground lift
Included 18 volt external power supply optimizes performance
Maximum Hi-Z instrument input level before clipping: +13dBu
Output connections: 1/4" Hi-Z unbalanced output w/ variable level control, XLR Male balanced line output, fixed level. Balanced line output level is +6dB higher than Hi-Z output with Level control fully clockwise.
Output Impedance: Hi-Z output: 7.5k
Balanced Line output: Less than 75
Gain Control: 9.2dB - 30dB, Variable, Hi-Z output, 15.2dB - 36dB, Variable, Balanced line output
Level Control: -inf. to 0dB, Variable, Hi-Z output only
Maximum output level before clipping: Hi-Z Output: +21dBu
Balanced Line Out: +27dBu
Frequency Response: +0, -0.5, 20-20kHz, both outputs, low-capacitance cable
THD+N: Less than 0.01%
Tone Control: 100Hz, 400Hz, 2000Hz Peaking, continuously-variable boost/cut, +/-16dB range.
Compressor: Ratio (fixed): Varies from 2:1 to 20:1 depending on compressor control setting.
Attack (fixed): Less than 5ms
Release (fixed): 100ms average (frequency-dependent for natural envelope tracking)
Compressor Control (6 Switchable settings): 1 = subtle compression, 6 = maximum compression. Turning clockwise Increases gain reduction (lower threshold) while simultaneously raising output level to match.
