Attention: The product does not include a remote control. If you need a remote control, please contact the seller to purchase it.

Flagship version: using 16 OP02-SM Class A discrete operational amplifiers+PW02-SM power module


PRE-A1000 Design Overview

1: Fully modular design, all sections are detachable and replaceable, and the whole machine is connected with European style sockets without any connecting wires!

2: Fully isolated chassis, strong and weak electrical isolation, AC/DC isolation!

3: Digital and analog separate power supply design, with completely independent power supply for the left and right channels; Relay soft control switch with remote control function; The simulation part adopts a two-level regulated power supply design, powered by dual TALEMA transformers, Nichicon KA series audio dedicated capacitors, high-precision, high signal-to-noise ratio, low internal resistance regulated power supply; The secondary voltage regulator adopts a modular design, which can achieve different sound requirements by replacing different modules! There are two types of secondary voltage regulation power modules available for selection! More module solutions are in progress!

4: 4-channel input, 4-channel output design; Input section with 3 XLR channels and 1 RCA channel; The output part adopts a dual channel design, with each channel being an independent front-end, equivalent to two front-end independent outputs! Each channel can be opened and closed separately!

5: Visual relay control gain design! Each output channel has 7 levels of gain adjustment!

6: 128 level relay volume module. Fine volume adjustment!

7: 16 fully discrete Class A amplification modules! Flexible replacement according to different preferences and needs, with different modules and sounds! At present, there are 2 types of modules to choose from, and more modules are under development!

8: We support high-end materials such as imported MILL-MAX operational amplifier sockets and pins, Vishay resistors, Vishay silver film capacitors, etc. from the United States!
Machine dimensions: length 434mm * width 378mm * height 80mm, excluding machine legs and connectors; Weight approximately: 15Kg
