Focusrite Isa one Mic preampClassic Mic Pre With Independent DIFeaturing a rugged, all-metal enclosure, ISA One mic pre combines the classic Focusrite microphone preamp with an independent DI channel and optional 192kHz A-D conversion. The the heart of the ISA dynamic range is the mic preamp with its Lundahl input transformer based on the original ISA 110. The input transformer provides a special character to your sound that can't be truly duplicated in any other way, while the modern twist of variable input impedance allows for a new degree of flexibility.Whether you're an musicians, engineer or producer, you'll appreciate the sound of the ISA One, with its front-panel DI input. The Direct box includes low/high impedance switching and an amplifier output, and its own feed to the optional A-D converter and separate rear-panel XLR output.SpecsGain Range (Mic)0dB to 60dB in 10dB steps 20 dB of variable gainSignal-To-Noise Ratio (Mic)106 dB relative to max headroom (9dBu)Frequency Response (Mic)At minimum gain (0 dB)-0.5dB down at 10Hz and -3dB down at 125kHzNoise (Mic)Noise at output with unity gain (0 dB) and 22 Hz-22 kHz band pass filter-97 dBuGain Range (Line)20dB to 10dB in 10dB steps 20 dB of variable gainInput Impedance (Line)10 kO from 10 Hz to 200 kHzFrequency Response (Line)At unity gain (0 dB)-0.3dB down at 10Hz and -3dB down at 200kHzFinishBlueHPF Roll-Off18 dB per octave (3 pole filter)FrequencyFixed 75Hz measured at the 3dB down pointW X D X H220mm (W) x 104mm (H) x 254 - 290mmWeight3.9 kg (8.6 lbs)
