Tascam MH-8 Hovedtelefon forstærker 8 kanaler
MH-8 er den ideelle hovedtelefonsforstærker til studio'et, scenen og installationer. Hver af de otte stereo-outputs leverer 250 mW per side med tre omstillelige kilder. To stereo-inputs kan deles til begge outputs og individuelle stereo direct-inputs er tilgængelige til hver af de otte kanaler. En hovedtelefonskanal kan benytte et hvilket som helst af input'ene, eller mixe dem sammen. MH-8 bor i en robust, rack-monterbar metal-chassis med indbygget strømforsyning, ground-terminal og ground-lift-switch.
