HI-END PASS A5 Pure Class A PASS Aleph-5 power amplifier Support XLR /RCA Input 60--90W 4--8 ohm stereo amplifier Audio Amplifier Boards

Introduction:

PASS Aleph-5 (PASS A5 for short), it is one of the world's famous pure class A power amplifiers, and it is also the HI-END amplifier sought after by more Audiophile among the class A power amplifiers of the same level.

A5 is an improved circuit design of PASS A3. HI-END material is very popular with Audiophile. Refer to the PASS A5 circuit of the famous American audiophile machine. The sound style is similar to the A3, but the A5 has more power. It has an 8 ohm speaker load. The output power can be up to 60W at a time. The sound field is wide, the low frequency is strong, and the driving force is better than that of the A3. It is one of the excellent circuit choices for pure A power amplifiers.

Adopt dual mono independent channels, independent rectifier for each channel, independent protection device, independent transformer, each transformer also uses shield to isolate magnetic interference, the power supply part adopts CRC filter mode, lower power supply ripple, each channel uses 120000uF Audiophile filter capacitor. Adopt HI-END double-sided immersion copper gold-plated PCB, with large area copper traces on the top, bottom and bottom, and can push tin, which is very stable when large current passes. Two-channel mirroring design, the circuit is fine to every solder The board, every line is carefully designed, and it is all the patience of the designer!

Using Audiophile HI-END component KOA 0.5W five-color ring high-precision low-noise resistance, amplifier tube source and output use DALE high-power Audiophile resistance, Audiophile audio capacitor, decoupling ROE Smurf axial capacitor, IRFP240 FET output tube and differential tube IRF9610 is precisely matched to make the midpoint output voltage as low as 50mV. The sound is sweet and honest, the music taste is very good, transparent, the low frequency flexibility is very good, and the human voice is very poisonous. It has the taste of a tube amplifier and a FET tube. The driving force of HI-END is one of the must-have power amplifiers for HI-END players!

Use 400W+400W OFC pure copper to customize the dual transformer independent power supply design. CMC 816 RCA+ gold-plated crystal terminal.

JP Canare with shielded signal wire + UK PRYSMIAN speaker output wire, the input signal is free from any interference, and the output wire bears high current. Everything is very easy.

This is a real high-power pure Class A power amplifier. It not only adopts the PASS style design, but also has an all-aluminum chassis with independent left and right heat sinks. Thick physical objects give people a very stable feeling. Its sound will surprise you. Sweet voice, thick air and very strong taste. When you listen to it in an audition room, it shows in your ears all the little details. Even the sound of the little bugs crawling in the music, you can hear it very delicately. It has no more noise and the background is very dark. A class A power amplifier needs a certain amount of time to warm up it. The sound is even more amazing when it is fully warmed up.
