Description

Line input: 1*RCA, 2*XLR

Line output: XLR * 1 (Preamp output)

Amp output: 1*6.35mm single-ended high resistance,

1*6.35mm single-ended low resistance

2*Three-core balanced Output, 1*four-core balance output

There is Pre-amp output,Gustard H20 could be used as Power amplifier and Pre Amp connecting Active Monitor.

 

Technical Parameters:

The power amplifier circuit uses separate Class A lines, each channel 2 pairs of power tube, a total of 8 pairs of power tube;

Each channel uses two independent amplifying units to form a symmetrical output line, Single-ended and balanced output are at the same time ;

The front class consists of a single 4-way amplifier circuit, using two LM49720 dual op amp;

Have a separate pre-stage output, can be connected to active speakers or pure after the class;

The use of matrix relay volume, effective to ensure that 4-way volume unanimous;

Native full-balanced architecture, from input to volume control to before and after zoom, without any conversion, complete four-way architecture;

The main filter uses Nikon nichicon audio capacitor KG gold tune

Equipped with third gear gain (high,middle,low), Support amp and line (XLR) output at the same time;

There are three inputs: RCA * 1, XLR * 2

The left and right channels each adopt a custom 50W audio ring transformer, completely independent of each other without interference;

All aluminum chassis, silver and black colors available;

Machine size: 330 * 260 * 65MM (without protruding parts);

Packaging size: 420 *360*175MM;

Package weight: 6.0KG;
