Garvan AT432-A 4-channel DSP stereo amplifier

Introduction: The Garvan AT432-A 4-channel DSP stereo amplifier is a powerful, compact 4-channel amplifier made in Italy, designed to provide the highest audio quality and flexibility in modern audio installations. With 320 watts of power per channel and advanced DSP technology, this amplifier offers excellent sound processing and reliable performance.

Performance and efficiency:

• Power: Each channel of the AT432-A delivers 80 watts into 2 Ω, 4 Ω and 8 Ω. At maximum power, you can achieve a total power of up to 320 watts per channel.
• Maximum output voltage/current: The amplifier offers a maximum undistorted output voltage of 142 Vpeak and a maximum output current of 15.6 Apeak.
• Energy consumption: The AT432-A is characterized by its efficient energy consumption. In idle mode it requires only 15 W at 115 V and 16 W at 230 V. At 1/8 of the maximum power at 4 Ω, the energy consumption is 76 W (115 V) or 78 W (230 V).

Thermal properties:

• Heat dissipation: The amplifier is designed for efficient heat dissipation. At 115V it produces 90 BTU/h at idle, while at 230V it produces 54 BTU/h. Under load (1/8 of maximum power at 4 Ω) the heat dissipation is 50 BTU/h (115V) and 102 BTU/h (230V).

Audio and DSP functions:

• Inputs: The AT432-A offers 4 balanced inputs (Euro 3.8 mm) and 2 unbalanced inputs (stereo mini jack). Inputs 1 and 2 can be connected in parallel.
• Gain control: The gain can be adjusted from 17 dB to 47 dB in 0.1 dB steps.
• Frequency response: The amplifier offers a frequency response of 20 Hz to 20 kHz with only ±0.5 dB deviation at 8 Ω.
• DSP capabilities: The AT432-A is equipped with a powerful 32-bit floating point DSP that provides 24-bit AD/DA converters and a fixed latency of 2.5 ms. It supports up to 100 ms delay per output for time alignment and various equalizer and filter functions.

Cooling and network:

• Cooling: The amplifier features a sealed design with internal cooling and can operate in whisper mode at 8W (26dBA), while the maximum volume is 30dBA.
• Network: The AT432-A is equipped with an RJ45 Fast Ethernet port that can be used for control and monitoring.

Dimensions and weight:

• Dimensions: 210 x 275 x 40 mm
• Weight: 2.6 kg

Conclusion: The Garvan AT432-A is a first-class amplifier that impresses with its compact design, high performance and advanced DSP technology. Ideal for professional audio applications and demanding installations, this amplifier offers both flexibility and outstanding sound quality.
