Description from Woodbrass :
The ISA428 MkII provides four of Focusrites prestigious transformer-based microphone preamps. It features the same classic circuitry and renowned audio quality found in the original at a new level of affordability. With selectable input impedance, direct instrument inputs and an optional eight channels of high-quality analogue to digital conversion, the ISA428 MkII creates the perfect front end for the discerning recording professional. First introduced in 1985, the ISA microphone preamp holds a reputation for outstanding transparency along with subtle warmth contributed by transformer core saturation. The addition of a variable impedance circuit allows ISA users to perfectly match the preamp with any microphone, or to use different settings creatively to shape the sound of the microphone. Unchanged for decades, the ISA microphone preamp topology offers incredible clarity and the signature Focusrite sound that makes it the top choice among many audio professionals today.Four instrument inputs, instantly accessible on the front panel, allow quick and easy connection without the need for a separate DI box. Extra processing can be placed between preamp and conversion via the units dedicated insert points, featured on every channel. Finally, accurate six-segment LED metering is designed to catch even the fastest transients on every channel. Over 25 years, Focusrite has earned a reputation for bringing superb audio quality and engineering excellence to an array of audio professionals. Whether youre looking to preserve the sound of your classic microphones, or searching for the perfect front end for your digital studio, the ISA428 MkII brings legendary tools to your studio at an exceptional new price.Front and rear connectivityAnalogue Channel Inputs (Inputs 1-4)-4 instrument 1/4 TS jack inputs on front panel -4 microphone XLR inputs on rear panel -4 line 1/4 TRS jacks on rear panel -4 insert return 1/4 TRS jacks on rear panel-4 ADC XLR inputs on rear panelAnalogue Audio Outputs (Outputs 1-4)-4 line XLR outputs on rear panel -4 insert send 1/4 TRS jacks on rear panelOther I/O-IEC power input connector 100Vac 240VacFront Panel Indicators-8 output meters, 6 segment -4 30-60 mic gain range selection indicator -4 +48V phantom power indicator -4 Phase indicator -4 Insert In indicator -4 Filter In indicator -4 Input selection indicators (Mic, Line, Inst) -4 Z In microphone input impedance selection indicators (Low, ISA110, Med, High) Clock select indicators (44.1, 48, 88.2, 96, 176.4, 192) -Ext clock indicators (Lock, Word clock, 256X)Weight5.5kg12.2lbsDimensions (W x H x D)480mm (W) x 88mm (H) x 280mm (D)19 (W) x 3.5 (H) x 11 (D)
