Description
HP400V2 is a professional 4-channel headphone amplifier. 7-digit LED used to control signal to avoid overload. Each channel features L MUTE/R MUTE knob, treble and low frequency EQ, output level control and output balance adjustable knob, all these knobs help you to monitor an ideal sound quality. Meanwhile, TRS and XLR two types connector make the unit applies to more occasions. Alum, acrylic (build-in blue LED light) and steel panel material make the unit beautiful, firm and durable.
Features:
- 1U rack shell helps headphone amplifier fixed on rack easily
- Ultra-musical High and Low EQ per channel for perfect sound adaptation
- Independent amplify circuit rejects interference and mix of each channel and makes each channel input purity signal
- Output level control and accurate 7-digit LED output meter per channel avoids sound distortion
- Adopts JRC performance chip to amplify the signal, also ensures low distortion and low noise
- Each channel features stereo XLR and 6.35mm connector
- Total 12 headphones outputs
