Universal Audio4-710d 4-Channel Mic Preamp
1/8
Independent shopping perspective
The Korena take
Four channels of Universal Audio's 710 preamp, each blending tube and solid-state paths, with per-channel compression. For studios tracking drums or full bands.
Strong match
Who this is for
- Tracking drums or a full band live to multitrack
- Studios wanting tube color without swapping preamps between takes
- Sources needing gentle compression on the way in
Consider the trade-offs
When to look elsewhere
- Solo songwriters who only ever record one source at a time
- Anyone needing an audio interface — this has no converters or USB
- Budget-conscious home setups where a single channel would do
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
-127dBu equivalent input noise at 56dB gain
The preamp stays quiet at high gain, so distant or soft sources do not arrive with hiss.
Detail 03
2.2M ohm Hi-Z input
High enough to load a passive guitar or bass pickup without dulling the top end.
Detail 04
4:1 compression with fast and slow attack
0.3ms fast attack catches drum transients; 2.0ms slow lets the stick hit through before clamping.
Detail 05
75Hz corner frequency, -23dB at 20Hz
The low-cut removes rumble and mic-stand thump while leaving kick and bass fundamentals intact.
Detail 06
600 ohm balanced output
Drives long cable runs to a converter or console without level loss.
Final check
Know before you order
- 01No converters or USB — you still need an interface with line inputs
- 02Rack space and balanced XLR or TRS cables for four channels
- 03Phantom power is 10mA per jack; check condensers that draw more
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I plug this straight into my computer?
No. It outputs analog line level. You need an audio interface or converter with line inputs to get the signal into a DAW.
02Does it have phantom power for condenser mics?
Yes, 48V at 10mA per input jack.
03Can I plug a bass or guitar in directly?
Yes. The 2.2M ohm Hi-Z input takes an instrument cable directly from a passive or active pickup.
04Is the compressor adjustable?
It runs a fixed 4:1 ratio with a 10dBu threshold. You choose fast attack and release or slow, not arbitrary values.
