Each mic pre of the Focusrite ISA 828 MkII microphone preamplifier has variable input impedance, to provide a range of subtly different sonic options when using microphones, including an ‘ISA 110’ setting, which replicates the impedance of the original Focusrite mic pre.
Up to 60dB of gain is available, with a further +20dB of continuously variable trim, providing a huge 80dB gain range. The high-pass filter has a fixed 75Hz frequency and 18dB / octave roll-off for minimising rumble, stand-borne noise and other low-frequency sounds.
The Focusrite ISA 828 MkII also features per-channel, six-segment LED meters, and switchable rear-panel insert points, which allow the use of inline processors such as compressors or EQs.
Dedicated connectors for mic and line-level inputs allow all sources to be connected simultaneously, making Focusrite ISA 828 MkII perfect for permanent installation in a rack. A switching power supply allows for efficient, cool operation, without sacrificing sound quality or performance, and increasing reliability over its predecessor.
The optional ISA ADN8 analogue-to-digital expansion card provides eight Dante, ADAT and AES3 outputs at sampling rates of up to 24-bit / 192kHz.And as with all Focusrite Pro products, wherever you happen to be in the world, you can rely on a three-year warranty if any Focusrite Pro hardware needs repairing or replacing due to a manufacturing fault.
