H-2 Headphone Amplifier Amp 800MW 1HZ-100KHZ Architecture For Lehmannaudio Black Cube Linear

H-2 Headphone Amplifier Amp 800MW 1HZ-100KHZ Architecture For Lehmannaudio Black Cube Linear

Description:
This headphone amp adopts the architecture for Lehmannaudio Black Cube Linear. Audiophile components are used and its circuit layout has been greatly optimized.

Features:
- The amp rectifier uses passivated diodes for Philips, which is fast. Use capacitors for Nichicon as main filters, voltage regulator tube for the United States ON. The consistency of the components is very good, and a good power supply part is the guarantee of power
- Gold-plated signal sockets & fully enclosed potentiometers will greatly increase its service life, provide excellent sound quality and lossless transmission
- As the pre-amplification part, 5532 is very musical. With op amp seat, other op amps can be upgraded
- All resistors use five-color ring high-precision thick copper foot resistors
- Film capacitors for WIMA and Siemens are used. And in-line capacitors use audiophile capacitors for Nichicon. Film capacitors are close to the op amp to ensure the shortest transmission distance
- The power amplifier part uses paired transistors for Lehmannaudio Black Cube Linear. To ensure consistency, we used a professional transistor DC parameter tester to pair the transistors
- Complete protection function can protect our expensive earphones at critical moments, and turn on the protection when DC power is ±0.9V. Our headset will not be switched on until about three seconds after power on, to ensure that there is no impact sound when power on. The output will be cut off immediately when shutting down, and there will be no impact sound
- The sound is generally balanced. The bass dive is very deep, the mid-frequency sound is mellow, and the high-pitched sound is beautiful. The revised circuit is expanded to 7HZ in terms of low frequency. The magnification remains unchanged, and the frequency response range is 1HZ-100KHZ
- The maximum power of the amp is 800mw, which can drive high-impedance headphones such as 701, 650, 880/990
- Chassis size: 88 x 33 x 110mm (WxHxD). The size does not include the size of front knobs and the back sockets)

Attention:
- Please make sure that the ground wire is in good contact before playing music. With a POWER indicator light on the front panel.

Package Included:
- 1 x Headphone Amp

Note:
- Power supply is not included. AC 12V power supply is recommended.
- It is assembled and ready to use.
