TASCAM’s MH-8 is the ultimate headphone amplifier for studio, stage and installation. Each of the eight stereo outputs gets 250mW per side with three switchable sources available. Two stereo inputs can be shared to any of the outputs, and individual stereo direct inputs are available for each of the eight channels. A headphone out can select any one of these inputs, or mix several together. A set of foldback outputs allow you to chain other MH-8s into a system.The MH-8 has a range stereo inputs that support various input sources; INPUT1 is equipped with XLR balanced and TRS balanced inputs, while INPUT 2 is equipped with XLR balanced and RCA-pin unbalanced inputs, and DIRECT INPUT from each headphone comes with TRS balanced inputs. The input jacks are also compatible with audio system of facilities, in-store audiovisual systems, and recording studio monitoring systems.Main Features:8 stereo 1/4″ headphone outputs250mW + 250mW at 32 per channelEach headphone output switchable to input 1, input 2 and direct input source (or a combination of the three)Master input gain controls16 1/4″ TRS balanced direct inputs4 XLR balanced inputs (CH1 & CH2)2 1/4″ TRS balanced inputs (CH1)2 RCA unbalanced inputs (CH2)4 TRS balanced foldback outputsGround lift switch and terminalSpecifications:INPUT 1 and 2:-Connector: XLR-3-31 (1: GND, 2: HOT: 3: COLD) 2 pairs-Input impedance: 56k-Nominal input level: +4dBu (1.23mV) -Maximum input level: +24dBu (12.3V)INPUT 1: -Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 1 pairs-Input impedance: 56k-Nominal input level: +4dBu (1.23V) -Maximum input level: +24dBu (12.3V)INPUT 2: -Connector: RCA Pin jack 1 pair-Input impedance: 22k-Nominal input level: 10dBu (0.3V) -Maximum input level: +10dBu (3.16V)DIRECT INPUT: -Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 8 pairs-Input impedance: 56k-Nominal input level: +4dBu (1.23V) -Maximum input level: +24dBu (12.3V)FOLDBACK OUT: -Connector: 1/4″ (6.3mm) TRS Phone jack (Top: HOT, Ring: COLD, Sleeve: GND) 2 pairs-Input impedance: 94k-Nominal input level: +4dBu (1.23V) -Maximum input level: +24dBu (12.3V)PHONES OUT: -Connector: 1/4″ (6.3mm) Stereo Phone jack 8-Maximum output level: 250mW + 250mW (32)Power: AC 100 – 240V, 50/60HzPower consumption: 36WDimensions (WHD): 19.0″ 1.73″ 11.0″ / 482 44 280 mmWeight: 8.4 lbs. / 3.8 kgIncluded items: Power cord, Rackmounting screw kit, Owner’s manual (with warranty)Frequency response:-PHONES out: 20Hz to 50kHz/100mW, 32 3dB-FOLDBACK out: 10Hz to 100kHz 3dBS/N ratio:-PHONES out: 85dB or greater (A-weighted, 20kHz, LPF)-FOLDBACK out: 90dB or greater (A-weighted, 20kHz, LPF)THD:-PHONES out: 0.05% or less (when outputting 100mW + 100mW 32, 20Hz HPF and 20kHz LPF)-FOLDBACK out: 0.07% or less (20Hz HPF and 20kHz LPF)Channel separation:-PHONES out: 50dB or greater (within a channel, A-weighted, 20kHz LPF, 1kHz nominal inout and output, 32 termination)-FOLDBACK out: 90dB or greater (A-weighted, 20kHz LPF, 1kHz nominal inout and output, 600 termination)Crosstalk:-PHONES out: 65dB or greater (A-weighted, 20kHz LPF, 1kHz nominal inout and output, 32 termination)
