Product Description

Gustard H20 Opamp Dual LM49720 Full Balanced Class A Headphone Amplifier Pre Amplifier Analog input: RCA standard input group, input sensitivity typical value: 2Vrms; input impedance 47kΩ XLR balanced input two groups, input sensitivity typical: 6Vrms; input impedance 2.4kΩ Front analog output (XLR): Output impedance 200Ω Frequency response: 20-80kHz /-0.1dB Signal to noise ratio:> 122dB Channel crosstalk: -130dB @ 1kHz THD + N: <0.0004% IMD: <0.0004% amp output: Frequency response: 20-80kHz /-0.1dB Signal to noise ratio:> 120dB Channel crosstalk: -120dB @ 1kHz THD + N: <0.0005% @ 6000mW into 32Ω LOAD IMD: <0.0005% @ 6000mW into 32Ω LOAD Maximum distortion output power 6000mW into 32Ω LOAD Maximum output power 12000mW @ 32Ω (THD = 1%) Load power: 64Ω 5360mW 150Ω 2680mW 300Ω 1340mW 600Ω 670mW

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; 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; 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; H20 Parameters: 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
