Please read more information below :

To the point where the input signal that affects most the sound quality passes, I adopted our original condenser as "LGMFC series" Panasonic Corp. film condenser "ECHU series". The excellent frequency characteristics, the operation of film capacitors breed very good In order to use these input signal. Also condenser to be used for the power supply line, we are involved in various ways. I have adopted the conductor polymer solid capacitors nichicon's impact point in the audio signal. I can say that the specifications of the ESR such as very good, and ideal for such applications. Of course, has become a selection of in consideration of the balance of tone with other parts and power supply voltage.
To resistance must-have in configuring the circuit, we use metal film resistors Bispa original having a favorable reception in various places also adopted in the past products "LGMFS" series. Precision error is small, and it is excellent especially the part having been including the "current noise characteristics, temperature coefficient and insulation resistance value", and the like. The lead foot displays using the default material with excellent frequency characteristics. Volume also the cornerstone of sound quality, I was adopted Bispa original 9mm angle volume "BSP92FG5" series. By dropping the (frame GND) terminal FG directly from the substrate, adopted a volume that has been "designed and custom-made" to reduce even a little noise reducing as much as possible the return route of GND.
Power switch also has adopted a specially designed SW firm of torque can afford. Use care on the material of the lead foot, and has adopted the high reliability that I did well. We also paying attention to the direction of the switch to prevent the malfunction of the power supply.
The film capacitor of small capacity to be used in various places, I have adopted the chip film capacitors, etc. of Panasonic Corporation. I'm going to use classification of material and varieties commensurate with it and where to use. I consider both of "sound quality and performance" to take as by combining well respectively.

BISPA has low and high gain , until now I haven't understand how to change to high gain , because the instruction manual in japan language only .

Anybody can help me please

I have 4 small pin for changing from low to high gain

Please see my pictures below :






Back pcb board :



Note :

In Low gain the power already big to drive LCD X and XC no Distortion.
I will only test the high gain maybe can drive my Abyss biggrin.gif

BISPA battery life with Panasonic E Volta is very good , until now is running about 36 hours , still got the the power biggrin.gif

Max battery use is 38 hours with E Volta Panasonic

Warming to Duracell battery :
As used Duracell took only 4 hours than the battery flat , the QC from duracell is very bad now .
Duracell is one of my favorite , but now no more because of QC very bad , even I haven't opened the battery , the fluid already running out
Can you imagine if you put Duracell in your Amps. And the fluid running out , that's really very bad

Original headphone amplifier "BSP-PHPA-03BT"

■ "BSP-PHPA-03BT" the major specifications ● "BSP-PHPA-03BT" was designed for that to drive the headphone connection method called "BTL connection" For an overview of the "BSP-PHPA-03BT" It is a headphone amplifier, making the circuit design in consideration so as to obtain the sufficient characteristics and quality. In addition, in order to achieve a "high-quality, sexual function and ease of use", I am also takes care of the selection of parts. In order to operate in the "AAA battery × 4 lines", the power supply is possible to handle easily. It becomes the headphone amplifier designed in consideration for electrical characteristics, to be able to correspond to the headphones or earphones a lot. In addition, it is also compatible with "SE connection" that can respond to headphones or earphones traditional by using a conversion cable.

1: circuit configuration.
The circuit will be the headphone amplifier that uses a "high-performance op amp low voltage operation". I adopt an operational amplifier which was developed as an audio for the gain stage. The drive stage, I have adopted a low-noise differential output op amps latest. It is enough to BTL output capable portable headphone amplifier full-fledged to sound well-balanced earphones or headphones variety.

2: Component configuration.
Each components of the circuit, is excellent both in terms of sound quality and characteristics in consideration of the balance of the whole, and has adopted carefully selected parts that are fully meet the specifications. Besides, I consider in order to obtain the "performance and high-performance simple" can be exhibited sufficient to adopt the parts of our original.

Specifications: 3.
You can enjoy it by connecting a headphone and earphone variety.
This headphone amplifier is built on the premise "to enjoy more comfortable music with headphones and earphones favorite" things.
It is possible to drive a well-balanced in the BTL output or headphones earphone variety. It is possible to be in the drive "(conversion cable when using the supplied) SE and BTL output output" the output from the headphone jack of the portable audio player So.

It is possible to switch the gain.
I prepare "(SE output is 3.5 times and one time) mode gain of 7-fold and 2-fold" the in order to adapt to various environments. It is possible to use in switching this. Since we have provided high gain mode and low gain to allow the volume properly adjusted, making it possible to operate comfortably achieved by taking advantage of by switching the gain mode to ensure proper volume control in this model.

I can use more than 20 hours with four AAA batteries.
Batteries, and handling Availability uses four easy AAA batteries. With four AAA rechargeable batteries 1.2V800mAh, it is possible to use more than 20 hours continuously. With the deterioration of the battery, and I will assume this specification in consideration as can be easily replace the battery.
