Description

Features:

1, mono structure, can easily be built into a single single independent channel.

2, OCL structure output, can be used without protection circuit.

3, FET input - MOS (precision pairing) tube output, classic PASS two-stage structure

4, fever component configuration, true HIFI enjoy.

5, MINI, modular design, can be used for short chassis.

6, all use the original new tube, the end tube 1A quiescent current precision pairing VGS.

7, recommended working voltage, single 19VDC (single 15VAC rectification) mono transformer power should not be lower than 20W, you can buy our HPOO single voltage rectifier power supply board.

8, it only has 6.5 times magnification, suitable for headphone amplifier or desktop small power amplifier.

9, input using Nichicon MUSE BP coupling capacitor, the low frequency is more flexible, while increasing the output coupling capacitance to 4700uF, increasing the low frequency quality.

Input voltage: DC 19V (transformer output voltage AC 15V rectification), Transformer power mono channel is not less than 20VA.

Output power: 5W+5W (Single-Ended Class A)

PCB Size: 75mm*50mm

Gain: 6.5 time

User comment:

PASS ACA is better than PASS ZEN, because the power is not large, about 6.5 times magnification, limited thrust, it is more suitable for headphone amplifier or desktop amplifier integrated machine, push the earphone or small speaker about 90dB, still have some fun and features.

It is suitable for listening to saliva songs, vocals, and pop music. For those who like listening to string music, big symphony, it is not suitable.
