Bass Boost. JDS Labs’s success is due to cMoyBB’s legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass. On a shoestring budget for an amplifier to boost the sound quality from your high- end headphones? The CMoy headphone amplifier is your. The CMoy headphone amp is a popular headphone amplifier that is small enough to carry everyday and powerful enough to drive headphones at higher levels.

Older cMoys use thin wires or protoboard to transfer audio signals. All our amps and dacs are covered by cmot 2-year transferrable warranty. Big-time bass from your pocket. Aml see our article Power is Volume for more information. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The good news is this can easily be fixed by heeadphone a headphone amplifier power levels needed to power larger hifi headphones.

External DC jack can be used to power the amplifier. Please remember to mention your headphones in the Order Notes field during checkout so that your amplifier will be customized for best performance!

Their customer service and support is equally awesome. These high-quality, Japanese made potentiometers feature smooth, noise free operation.

In this case it is necessary use also two electrolytic capacitors C1a and Jeadphone. NJM op amp, features exceptionally low noise and distortion values.

CMoy Headphone Amplifier

Just gonna hang out in my office with headphones all night. First of all I prepared the schematic. Arduino Prototype uses all standard through-hole head;hone for easy construction, two of which are hidden underneath IC socket. I had mine customized as well. A technical summary ships with cmky custom cMoyBB.


We hand assemble each cMoyBB and tweak output power and bass boost for your equipment. Many virtual ground circuit options are presented in the various CMoy tutorials found online. Just the way a nice pair of loudspeakers needs a quality amplifier to sound their best headphone’s also need quality amplification to sound their best.

I’ll be back for any possible audio akp Daniel W. Even was caught off by the esd bag it was contained in. The amplifier’s design is quite simple. Firts possibility is use passive voltage divider, ammp of two resistors R1a and R1b. It also analyzes transistor’s characteristics such as voltage qmp gain. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Simply specify your headphones during checkout. We now offer a low impedance version that we highly recommend if you are using headphones under 75ohms.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

How to Build the CMoy Pocket Amplifier

Purchased a couple devices from JDS. Switched on, bass increases up to 9. Does not charge batteries.

In my post you can find my experience with creating this simple headphoone very good amplifier. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, cnoy, etc. As the op-amp directly drives headphones some care should be given when choosing an op-amp, some op-amps are not suitable for such low impedance loads and will result in poor performance.


From Wikipedia, the free encyclopedia.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Absolutely recommend this shop for high quality audiophile equipment. By using this site, you agree to the Terms of Use and Privacy Policy.

As a result plugging hifi headphones directly into these devices will yield underwhelming, flat-sounding audio. My new cMoyBB head amp just arrived! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality. The output power coming from most devices is inadequate to power larger hifi headphones.

CMoy – Wikipedia

Few months ago I decided built this amplifier also. The Cmoy headphone amp is just such an example My power supply unit has two possibility. Specify your headphones during checkout and we’ll optimize gain, bass boost, and output power for best performance with your headphones. You can help Wikipedia by expanding it. Optional charging support also provides convenient, integrated 9V NiMH battery charging. I’ll be back for any possible audio needs”. Ideal for portable use of most headphones.

This sound technology article is a stub. Customized 1x9V cMoyBBs produce higher output current, which is useful for driving low impedance headphones. Power System cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters.
