Alctron HP800 V2

8-Channel Headphone Amplifier
Alctron HP800 V2 is a headphone amplifier which features 8 independent stereo headphone channels. Each channel has its own volume control knob, adjusting the volume when it is too high or too low. The 7-level indicator indicates the output level, if the red light lit, you should lower the volume to avoid distortion. Also the Mono/stereo and channel choose button help you to monitor an ideal music sound you wanted.

Features:

• 1U rack shell helps headphone amplifier fixed on rack easily
• Mono/stereo switch per channel for more flexibility
• Output level control and accurate 7-digit LED output meter per channel avoids sound distortion
• Direct input connector on each channel for easy connection of any sound source
• Independent amplify circuit rejects interference and mix of each channel and makes each channel input purity signal
• Adopts JRC performance chip to amplify the signal, also ensures low distortion and low noise
• Rich ports suitable for various applications
