JL Acoustic Labs
 
Portable Headphone AMP
MCU Portable Headphone Amplifier BAB-1-XA / BAB-3-JE
 
 
 
AD / DA Ultra Micro Control Unit System.
 
Neither in Discrete OPAMP, portable headphone amplifier that performs amplified by MCU.
 
As a result of pursuing a high-quality sound, I was able to get an overwhelming performance breakthrough technology than ever before.
 
Amplification
 
 
 
Rather than a conventional amplifier circuit, such as discrete and OPAMP, processing is performed in the MCU, I have achieved a low noise and sound overwhelming.
 
By connecting a portable player, CD player, PC, smartphone, tablet, etc., you can easily play high-quality earphones or headphones.
 
MCU
 
 
 
A microprocessor called Micro Control Unit, after conversion to digital analog voice, digital voice data analysis is divided into frequency bands, from bass to treble their own by SFC (Sound Field Control) amplification and sound processing optimum processing do. 
Then we again converted to analog outputs by the MCU.
 
Potential
 
 
 
We realize a high-quality sound further with the coupling capacitor of Germany MUNDORF. 
Ones that are used in audio speakers and other high-end luxury, this capacitor is required 200 hours from 100 hours aging time to the original performance. 
Than doing a forced aging, such as playing music or when not in use while you are sleeping, I would like you also enjoy the sound will change the aging period in the feelings go out for a long time.
 
Use the parts that were carefully selected and reliable TE Connectivity, AVX, TDK, etc. In addition to MUNDORF, produce a high-quality and ultra-low noise.
 
Built-in battery
 
 
 
Done from the terminal for mini USB, charging the battery can be charged conveniently, such as personal computers and mobile. 
And fully charged in about four hours, operating time should offer your time near 300 depending on the usage. 
This is because there is almost no plant consumes the electric power to operate in the MCU without using an amplifier circuit and discrete OPAMP. 
We carried out high-quality power supply efficiency overwhelming sound processing and amplification process.
 
We are also equipped with overcharge and over-discharge protection circuit also.
 
Action indication
 
You can check the operating status LED. 
During normal operation, blue, red during charging, charging error is blinking red. 
This course can also be used while charging.
 
Lightweight
 
And weighs about 125 grams, part of the weight is convenient to carry portable amp waiting for a very light and small degree of built-in rechargeable battery and case.
 
BAB1-XA? BAB3-JE?
 
 
 
BAB1-XA that made the tuning also matches the earphones as well as headphones. 
Two models are BAB3-JE, which is optimized for high-impedance headphones.
 
BAB1-XA is a single-core MCU, BAB3-JE is equipped with a dual-core. 
By the power of dual-core MCU, BAB3-JE is frequency band division processing has become more precisely, it is about three times of BAB1-XA also process code.
 
There is also a sound choice of earphones or headphones for your, please choose to compare BAB1-XA/BAB3-JE in song to listen well and your equipment.
 
AD / DA Ultra Micro Control Unit System.
BAB-1-XA / BAB-3-JE
 
 
 
I have completed over one year from the prototype on display at the festival of autumn 2011 headphones.
 
Size, light weight, operating time, and sound quality. 
This model distinguishes itself JLAL was completed, and until now portable headphone amplifier.

※ Please keep it in a safe place because you will need (such as a receipt or invoice) documents can be checked from the date of purchase.
Since the MCU is processing the input signal, if there is no voice input is idle time, the signal processor sounds like white noise during silence. MCU for processing is performed based on the audio input signal, if it exists, and is specified signal processor sounds like white noise is eliminated.

※ configuration and specifications of the products are subject to change without notice due to improved quality and parts supply situation.

Wow 300 hrs of battery run after 4 hrs of charge. That's impressive and unbelievable.

 

Can some of the head-fi'ers from Japan order for us? normal_smile%20.gif

Rudi you need to do the testing for us. 

 

Remember the saying, "if it's seems too good to be true, it usually is".

 

It seems very unlikely it will surpass the Fostex HP-P1 sound quality. tongue.gif

Just saw this... I've been interested in the BAB1 for a while... I'll be trying it out soon. Unfortunately, mail service doesn't run during the CNY period, so I have to wait another couple of weeks before I get it. I'll post impressions.

Yes Tom 

 

out the box sound quality awesome , in term of detail, clarity , soundstage , separation , midrange and the important think is dead silent .

this one of the best my portable amp collection.

This is digital portable amp with mundorf chip, but SQ is far from the digital sounding amp .

The midtrange sp sweet is sound like from tube .

the Sound zig from BAB III JE is like my Tralucent T1 , BAB III JE is smoother .

Yeah, I spoke to the designer, JL, and he said he enjoyed analog LP recordings a lot; he didn't want his amp sounding like a "digital" sounding amp. It's good that you think the amp is pretty silent. The BAB3 is made for higher power delivery than the BAB1. I got the BAB1-MC Edition L, which is tuned for low-power delivery for BA earphones.
