Detail 01
Valve/tube circuit
The tube adds harmonic content, thickening the midrange and rounding sibilance instead of reproducing the source exactly.

RODENTK Large-Diaphragm Tube Condenser Microphone
1/2
Independent shopping perspective
The Korena take
A one-inch tube condenser with its own power supply. For vocal and acoustic tracking where you want warmth and body rather than clinical accuracy.
Strong match
Who this is for
- Lead vocals needing weight and a softened top end
- Acoustic guitar or brass tracked in a treated room
- Studios with space for the mic and its supply
Consider the trade-offs
When to look elsewhere
- Live stages or fast setups — it needs mains power
- Anyone wanting pattern options; this is cardioid only
- Reference-flat capture for classical or measurement work
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
Dedicated power supply
Runs from its own included supply rather than 48V phantom, so it needs a mains outlet near the stand.
Detail 03
1-inch capsule
A large diaphragm gives fuller lows and a stronger proximity effect, which flatters voices worked close.
Detail 04
Cardioid only
No omni or figure-8. Rear rejection is fixed, so room control comes down to placement and treatment.
Detail 05
158dB max SPL
Very high headroom. Safe in front of loud amps, brass and drums without the capsule overloading.
Detail 06
760g
Heavy for a mic. It needs a solid stand and a mount rated for the weight, or it will droop.
Final check
Know before you order
- 01Give the tube a few minutes powered before the first take
- 02Side-address: sing into the face of the mic, not the top
- 03The power supply takes an outlet and desk or rack space
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does the NTK run on phantom power?
No. It uses its own power supply, which comes with the mic. You still need a preamp channel with gain for the mic's output.
02Why is a tube mic different from a regular condenser?
The valve stage adds harmonic colour and compresses peaks gently, so vocals sound thicker and less brittle. It is a flattering sound, not a neutral one.
03Can I record loud sources with it?
Yes. 158dB max SPL is high headroom, so guitar cabs, brass and drum rooms are all within range.
04How long should I let it warm up?
Several minutes powered before tracking. Tube circuits drift while cold, and the tone settles once the valve reaches temperature.
