The SAS Luna provides 12 high quality microphone preamps, each with a very wide gain range and individually switchable +48 VDC phantom power. Luna also provides 8 line level fully floating audio outputs. An embedded web server allows configuration and monitoring of inputs and outputs. The Luna pairs well with an SAS Nucleus DSP Engine to provide comprehensive dynamics processing, EQ and AGC.
The ISA 828MkII 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 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.
