The Effectrode Leveling Amplifier, also known as the 'LA-1A', is a studio- grade vacuum tube compressor in a pedal form. It is designed to enable artists and engineers to extract every nuance from a musical performance without compromise. The pedal features a parallel tube plate design, which is typically found in high-end tube phono-stage preamps for turntables, resulting in reduced noise floor and exceptional signal-to-noise ratio.
Key specifications and features include:
- Input impedance: Greater than 1MΩ
- Output impedance: Less than 1KΩ
- Controls: Peak Reduction, Gain, Boost, Attack, and Knee
- Features: Dynamic tube equalizer, active tube boost, and tube-buffered
output circuitry
- All-tube: Super low-noise parallel tube input stage (four tube sections)
operating in class-A
- Photo-optical: Ultra-linear, low distortion photo-resistive attenuator with
fast attack time (< 1ms)
- True bypass with 'anti-pop' foot-switching circuitry
- Power requirements: 12VDC @ 1A center positive
- Dimensions: Width 7.5", depth 4.8", height 1.3"
- Weight: 2lb
- Construction: Solid die-cast aluminum box with a tough light-grey powder
