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, transformer output and a hard wire bypass switch. 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.
Input connection: 1/4″ Hi-Z unbalanced instrument input
Input Impedance: ~500kΩ
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: 7.5kΩ
Balanced Line output: Less than 75Ω
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.
Power Supply: +18VDC @ 650mA
