TASCAM MH-8

Features

• High-power headphones amplifier with flexible signal routing
• 8 channels for one pair of stereo headphones each
• 2 stereo inputs assignable to each headphones channel (input 1: balanced XLR/TRS, input 2: balanced XLR / unbalanced RCA)
• Input level control, signal presence and overload LEDs on both stereo inputs
• Additional switchable direct stereo input (balanced TRS) on each headphone channel (left input can be used for mono signals)
• High output power (250 mW + 250 mW for each headphone)
• Level control, signal presence and overload LEDs on each headphone channel
• Each channel switchable to mono
• Foldback outputs allow stereo input signals 1 and 2 to be looped through to other units
• Ground terminal and ground lift switch on rear panel
• Easy replaceable fuse
• 1U rack-mountable chassis
