Sescom LN2MIC-PMD620 3.5 Line to Mic 33dB Attenuation Cable - DSLR

In this review the Sescom LN2MIC-PMD620 is evaluated as a focused solution for users who need to feed a line-level recorder into a camera mic input without overloading it. The bottom line: it is aimed at videographers and sound recordists who want a neat, reliable cable that converts the Marantz PMD620 or similar line outputs to a camera mic jack with proper attenuation and impedance matching. The reviewer found the cable simple to use, well engineered for low noise, and particularly notable for its labeled ends and isolated shield design, which together make on-set connections faster and quieter.

Key Features

• 33dB L Pad attenuator: reduces line level output to the camera mic input sweet spot so recordings avoid clipping and distortion.
• Proper impedance design: matches impedances to assure efficient voltage transfer and keep noise low across the connection.
• Isolated camera-end shield: prevents shield noise from coupling into the camera ground for cleaner audio on location.
• 1% metal film resistors: precise resistor values maintain consistent attenuation between stereo channels for balanced sound.
• Labeled cable ends: clearly marked connectors speed setup and reduce connection errors when swapping gear in the field.

Who It's For

The Sescom LN2MIC-PMD620 is best for independent filmmakers, ENG shooters, and audio recordists who use a field recorder such as a Marantz PMD620 and need to feed that recorder into a DSLR or other camera mic input. It is practical for anyone who wants a compact, single-cable interface that preserves audio quality without adding a bulky adapter box.

Users who need long runs, active electronics like powered attenuation, or multi-channel digital converters should look elsewhere; this cable is a passive, short-run 9 in solution designed to bridge specific analog outputs to camera mic inputs rather than replace a mixer or multi-channel interface.

Pros & Cons

Pros

• Accurate 33dB attenuation keeps line outputs from overdriving camera mic inputs for reliable recordings.
• Careful impedance matching and isolated shielding reduce noise and preserve signal integrity.
• High-precision 1% metal film resistors ensure consistent stereo attenuation and matching between channels.
• Short 9 in length and labeled ends make it a compact, user-friendly cable for quick setups.

Cons

• Passive design and short length limit use to nearby recorder-to-camera connections rather than long cable runs.
• Not a substitute for powered adapters or multi-input mixers when complex routing or gain control is required.

Frequently Asked Questions

Will this cable prevent my camera from clipping when using a field recorder?
Yes, the 33dB L Pad attenuator reduces line level to mic input levels so the camera mic preamp is far less likely to clip.

Is the shielding effective for noisy environments?
The cable has an isolated shield on the camera end specifically to reduce shield noise coupling into the camera ground, improving noise performance on location.

Can this replace a mixer or powered adapter?
No, this is a passive 9 in cable designed for short recorder-to-camera connections and does not provide active gain control or multiple inputs.
