REPLICATE

Hagerman REPLICATE User manual

  • Hello! I've reviewed the user manual for the Hagerman REPLICATE Ground Loop Eliminator Pedal. This pedal is designed to drive multiple amplifiers from a single guitar signal while preventing ground loop hum. It provides ground isolation using opto-isolators and offers wide bandwidth down to 10Hz, making it suitable for bass and synths. I'm ready to answer any questions you may have about the features or specifications described in the manual.
  • What is the purpose of the REPLICATE pedal?
    How does the REPLICATE pedal prevent ground loops?
    Is the REPLICATE pedal suitable for bass and synthesizer?

REPLICATE – Ground Loop Eliminator Pedal

Description
The REPLICATE pedal is designed to drive two or three amplifiers at the same time from
a single guitar or pedal chain.
The main output is a direct connection to input, thereby providing the load seen by
guitar. Copied outputs are each independently isolated from ground in order to prevent
ground loops, which typically end up injecting hum or buzz into the signal path. Internal
opto-isolators eliminate such undesirable noises.
Bandwidth is exceptional, operating all the way down to 10Hz, making the pedal useful
for bass and synthesizer as well. Output impedance is superbly low, capable of driving
long lines without treble loss.
Earth ground for guitar and pedals provided by Main Amplifier, as shown.
