Delivering power and durability, theF388-2-Q 4-Channel Headphone AmpfromLake Peopleis a versatile, rack-mountable studio headphone and speaker amplifier, providing 4-channels of low-noise amplification for headphones between 16 and 600 ohms as well as studio monitors and loudspeakers. Ultralow-impedance amplifier outputs ensure optimal performance with the lowest impedance headphones, and pre-gain can be set internally between -12 and +12 dBr for refinement when matching to your preferred listening device.
The F-388 comes with four balanced XLR inputs (left and right), four stereo 1/4″ headphone outputs, and four stereo 1/4″ line outputs. Each channel sports dedicated volume and balance adjustment knobs and the unusually high internal operating voltage ensures a more than adequate sound level is maintained, even when used with very-high-impedance headphones.
