Sony ECM-77 Overview

The black Sony ECM-77 is a miniature omnidirectional lavalier microphone designed for professional broadcast, sound reinforcement, and recording applications. The condenser mic element's tiny profile allows it to be easily concealed in performance and broadcast situations.

The omnidirectional polar pattern provides even frequency and sensitivity response at the direct and off-axis sections of the microphone capsule, helping to provide consistent levels, even if the talent isn't speaking directly toward the mic.

The ECM-77 provides a wide frequency response of 40 Hz to 20 kHz for accurate reproduction of speech and vocals and requires 1.1 to 10 VDC power from a compatible wireless transmitter or similar device. A windscreen to reduce wind and breath noise and a tie clip to attach the mic to clothing are included.

Unterminated (Pigtail) Leads
Customizable Wiring
  • Pigtails: Works with Sony transmitters equipped with This version of the mic features unterminated pigtail leads allowing for custom wiring.
  • Third-Party Devices: The ECM-77 will work with many third-party wireless transmitters and portable audio recorders that are equipped to supply 1.1 to 10 VDC through a Sony wiring configuration.
Dependable Performance
Small Size
The ECM-77's capsule is 1/4" in diameter and 1/2" in length, allowing the mic to be used on stage or on camera while remaining inconspicuous.
Headroom for Standard Speech and Vocal Applications
The mic can handle up to 120 dB SPL without distortion—adequate headroom for most presenters, performers, and instructors.
Omnidirectional Polar Pattern
The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent turns away from the microphone.
Wide Frequency Response
With its 40 Hz to 20 kHz frequency range, the ECM-77 provides accurate and transparent reproduction of speech, vocals, and instruments.

Sony ECM-77 Reviews

Only mike to use with Sony transmitters

By warnerl

This mike has a good pattern, small enough to hide, great for the speaking vocal range, and essential for use with Sony transmitters. Sony transmitter pack a lot into their signal, (encryption, pairing signal, along with the freq. you are transmitting on) and this mike is shielded properly to prevent transmitter noise and interference.

Nice sound!

This is a very nice sounding mic. It's no mystery as to why many are using this on pro applications and sets.

Decent mic

This mic is for my slot-in wireless package used on my Sony F800. The build is good, audio is nice and clean, it's not too directional so you can place the mic in hidden clothing areas and point it in a convenient direction. If you have a few extra bucks, i'd recommend going for the Sanken model over this one.

I would buy this product again and agai

As with all things video no matter how much you spend you will always have to spend more. The standard mic that comes with the Sony UWP-V1 kit I found to be horrible, after some research I went with the ECM-77BMP to replace the kit mic. It is a huge improvement , sound clarity is 10/10. This was extra money I was quite happy to spend!

A giant step upgrade!

I thought the stock mic with the Sony UWP V1 was pretty good, but after hearing so much about this one I decided to pull the trigger. I had two wireless sets and needed a backup, and now this is my main mic and one of the stock mics is backup. This mic has taken my work to the next level. A very good wireless system with an average mic is cheating yourself. The richness gives that pro feel I've been looking for. A happy camper!

Caps go bad regularly

When it's working, it sounds great. The problem is, we use this product 10+ hours per day for live news broadcasts, and they are not robust enough. We have had 5 caps go bad in just as many months. Never seen anything like it. Costing us a lot of money to have to replace on a regular basis. I'm going to dish out more money this time for the Sanken mic in hopes that it will have a longer life.

The Sony ECM-77 Miniature Omnidirectional Lavalier Microphone with Locking Sony 3.5mm Connector and Sanken COS-11D Lavalier Microphone are both high-quality, professional microphone choices. Selection between the two is mostly a matter of personal preference but can also be influenced by application, continuity, and compatibility.

Would this work on the Tentacle Track E?
Asked by: Angelito
Found answer to my own question but sharing for others who may find it useful: This lav can work with other devices if the device can supply 1.1 to 10 VDC power. The Tentacle Sync Track E has a mic plugin power up to 5V so it can work with this lav mic.

question

I have a wireless lavalier mic system. The microphone is model sony emc77BMP and the receiver is sony wrt 805.It is not working well, since it catches a lot of interference when recording on longer distances that 30cm, and especially in the city, and as such the wireless part of the system is practically useless for me, but the lavalier mic is very good, and I want to connect it directly to my field-recorder a Tascam DR-40. The input in the recorder is XLR, while the lavalier has a jack (male). I need an adaptor from jack to XLR, and I am wondering about 2 things:1) The adaptor should be a jack (female) to a XLR (male), but is anything else needed, like a converter of electric tension between the lavalier and the field-recorder, or does the lavalier connect directly to the field-recorder?2) The field-recorder offers different settings for recording. One option is to record directly, and one option is to record using phantom-power. Which option should I use when connecting the lavalier directly to the field-recorder via an adaptor (omitting the wireless receiver and emitter system)?
Asked by: John D.
The lav can plug directly into the DR 40. All you will need is a 3.5mm to XLR adapter and phantom power from the recorder. Then you can plug the lav directly into the XLR mic input on bottom of the DR 40. B&H # QUQAD2 see below.

question

Could this microphone also be used with the Tascam DR-70D?
Asked by: Thomas
Just heard back from Tascam and they confirm that plug-in power is about 3 volts. So mike would have to go through wireless and then into Tascam via XLR.
