AS NEW Focusrite ISA 828 MkII - DISPLAY MODEL - 8-Channel Mic Preamp 2023. 12 Month Warranty

FOCUSRITE ISA 828 MKII. DISPLAY MODEL - AS NEW - 12 MONTHS WARRANTY No box or expansion card WORLD WIDE SHIPPING - CAN HELP WITH IMPORT TAXES THIS SALE IS FOR 1 UNIT of 3 UNITS AVAILABLE - CHECK OTHER LISTINGS Overview of these units Sharing the simple mic preamp design of the original Focusrite ISA 110 module from the Focusrite Studio Console, ISA 828 MK2 incorporates eight of Focusrite's classic mic preamps, with Lundahl LL1538 transformers on every input. Each channel has the option of mic or line inputs, while inputs 1-4 also feature instrument inputs on the front panel. Each mic pre 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 with fixed 75Hz frequency and 18dB/octave roll-off. ISA 828 MK2 features high-pass filters, calibratable 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 ISA 828 MK2 perfect for permanent installation in a rack. New to the ISA 828 MK2 is an updated power supply that allows for more efficient power consumption, a reduction in heat generation, and extremely reliable operation. The optional ISA ADN8 analogue-to-digital expansion card provides eight Dante, ADAT and AES3 outputs at rates of up to 24-bit/192kHz. Key Features Classic ISA mic preamp design featuring Lundahl LL1538 input transformer Switching power supply design allows for efficient and cool operation Front-panel instrument inputs to the first four channels offer two impedance options: High (2.4 MΩ) and Low (470 kΩ) Line inputs with dedicated input connectors and front-panel switch Switchable input impedance including classic ISA 110 setting High-pass filters Switchable insert points when used with A-D card Calibratable, per-channel six-segment LED peak-level meters Optional A-D card with up to 192kHz, 24-bit sampling offers high-quality, precision digital audio conversion to Dante, ADAT and AES3 (sold separately) Eight-channel mic pre and optional A-D card with Dante The ISA 828 MkII incorporates eight of Focusrite's classic mic preamps, with Lundahl LL1538 transformers on every input.

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 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 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.
