REFURBISHED - Oktava МД-64М / MD-64M November 1980 - XLR

OKTAVA МД-64МTHE SOVIET PORTABLE DYNAMIC

The Oktava МД-64М (MD-64M) is a Soviet dynamic microphone developed primarily for portable recording and speech applications. Rather than aiming for wide-band studio reproduction, its design reflects the priorities of portable Soviet recording equipment: intelligibility, directionality, simplicity and durability.

This particular microphone is marked 11 1980 г., indicating production in November 1980.

OPTICAL CONDITION — B
Good vintage used condition. Structurally very well preserved, without significant impact damage or deformation. The textured green and yellow surfaces show visible wear and age-related marks.

TECHNICAL CONDITION — A
Fully functional and tested. Original internal components retained. Professionally converted to balanced XLR. The original on/off switch has been electrically bypassed for a direct, permanently active signal path.

INCLUDED: 

MICSTERLAB storage bag

MODEL DESCRIPTION

The MD-64M belongs to a distinctly Soviet category of portable speech microphones. It was intended for use with portable tape recorders and dictation/recording equipment, and examples are documented as part of systems such as the portable П-180-М recorder.

Its proportions are particularly charming today. Despite being conceived as a portable microphone that could be attached using its dedicated clip, it is considerably larger and more substantial than what we would now expect from anything approaching a lavalier or personal microphone.

The tapered body, large attachment clip, brightly contrasting plastics and red switch make it an unmistakably late-Soviet industrial object.

BUILD & DESIGN

The MD-64M uses a passive dynamic moving-coil system in a strongly tapered housing. The large original clip allowed the microphone to be attached for portable speech recording rather than requiring a conventional microphone stand.

Its construction is simple and functional, with the emphasis placed on durability and practical speech capture rather than miniaturisation or extended studio performance.

This example retains its original internal components but has been converted at MICSTERLAB to balanced XLR, making it immediately usable with modern microphone preamps. The original switch was bypassed during the conversion and the microphone is therefore always active when connected.

SOUND

This is not a particularly beautiful or natural-sounding microphone — and there is no reason to pretend that every historical microphone is.

Its response is narrow and strongly speech-oriented. There is an emphasis through the upper midrange that keeps speech present and intelligible, while the upper-frequency response is very limited. On this example, useful response extends only to approximately 9 kHz.

The result is a sound that can be slightly nasal, somewhat dull and distinctly bandwidth-limited at the same time. Transients are also reproduced with relatively little speed or definition, giving the microphone a somewhat softened, compressed impression on more complex sources.

For conventional modern studio recording, these would normally be limitations. Here, however, they are also a clear expression of what the microphone was designed to do: capture intelligible speech through portable recording equipment, not provide high-fidelity studio reproduction.

That makes the MD-64M interesting today precisely when its limitations are useful — for deliberately narrow speech, vintage communication effects, character vocals, lo-fi recording or simply as a wonderfully unusual piece of Soviet microphone engineering.

FREQUENCY RESPONSE

This example shows a strongly restricted bandwidth with useful upper-frequency response reaching approximately 9 kHz, combined with a noticeable upper-midrange emphasis.

The combination explains much of its character: speech remains surprisingly understandable despite the missing top end, while music and transient-rich material quickly reveal the limitations of the system.

The MD-64M is therefore less a forgotten studio secret than something arguably more interesting: a microphone that still sounds unmistakably like the job it was built to perform.
