DPRTV: Pre-Amp Shootout Fujifilm X-T3/X-T4, Sony a7III, Panasonic S1H, Olympus E-M1 Mark III, Nikon Z6, and Canon ES-1D Mark III
DPRTV did a Microphone pre-amp Shootout with a Fujifilm X-T3 (X-T4 has the same preamp), Sony a7III, Panasonic S1H, Olympus E-M1 Mark III, Nikon Z6, and Canon ES-1D Mark III. Below you can see a summary and the results or you can watch the video above.
Pre-amps amplify things before they are recorded
Just about everything needs to be brought up to a level that it can be heard in your software or camera
Good preamps have a high signal with a low amount of noise
Bad preamps have noise that gets mixed into the signal
Your preamp is the celling of quality you’re going to hear so a bad preamp with a good mic will be limited and you might hear a lot, but there will be noise mixed in.
A good preamp with a bad mic will let you hear everything the mic can capture, but it won’t fully utilize the preamp
mediocre preamps and below also add hiss
Proper audio levels
Canon ES-1D Mark III was fantastic
Fujifilm X-T3/X-T4 was really good
Nikon Z6 was solid
Olympus E-M1 Mark III was middling
Panasonic S1H favorite
Sony a7III sounded bad with lots of hiss and noise
Low audio levels out of the mic -20db below ideal
Each camera had more noise
Canon ES-1D Mark III had a digital not consistent noise
Fujifilm X-T3/X-T4 running water sound with a high-level whine
Nikon Z6 running water sound
Olympus E-M1 Mark III running water sound
Panasonic S1H running water sound
Sony a7III was really really really bad it boosted the bad sound
High audio levels out of the mic +10db above ideal
One thing that helps hot signals is a limiter, attenuator, or compressor to take a hot signal and dampen it down
Canon ES-1D Mark III did a great job and it sounded natural with the limiter
Fujifilm X-T3/X-T4 was a little crunchy and the limiter affected the audio
Nikon Z6 was a lot like the Canon
Olympus E-M1 Mark III was not as bad as the Fujifilm, but not as good as the Canon and Nikon
Panasonic S1H limiter didn’t sound right
Sony a7III still sounds like hot garbage
Rankings
Canon ES-1D Mark III – Didn’t expect it to sound this good
Nikon Z6 and Panasonic S1H (tie) – Both have issues, but not bad
Fujifilm X-T3/X-T4 – good sounding camera
Olympus E-M1 Mark III – not as good as the rest of the cameras
