Thanks to its convenient 25 pin D-Type connectors, the ISA828 also integrates quickly and seamlessly with ProTools HD, as well as other popular hard disc recorders and mixing desks. More information about the ISA828 A-D converter option can be found here\u0026lt;=link to ISA428\/828 ADC option page\u0026gt;.\u003c\/p\u003e\n\u003cp\u003eThe microphone input stage additionally includes a variable impedance circuit, allowing the user to switch between four carefully selected input impedance settings. The original ISA110 setting is supplemented by three further impedance settings to either perfectly match the preamp with any microphone, thus maximising level, or to use different settings creatively to shape the sound of the microphone being used.\u003c\/p\u003e\n\u003cp\u003eThe four front panel instrument inputs also feature high and low impedance options to provide a comprehensive and accessible DI solution. Insert switches are also featured on every channel, should the need arise to place extra processing between the preamp and converter. Vintage design 75 Hz \/ 18dB per octave high pass filters are also provided on every channel, ensuring unwanted low frequencies are effectively eliminated.\u003c\/p\u003e\n\u003cp\u003eFinally, every channel features a six LED input meter, complete with global precise meter trim. Metering has been designed to utilise the same reference points as Digidesign’s Pro Tools HD™ system and provides clear and accurate input metering, independent of the DAW.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eEight ISA series transformer-based preamps\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eIn a single robust 2U chassis, offering the classic Focusrite pre at its lowest cost-per-channel to date.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNew optional eight-channel 192kHz A-D converter\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eEmbodies cutting-edge conversion technology, incorporating Focusrite analogue circuitry to deliver the best A-D performance on the market, bar none.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eConvenient 25 pin D-type connectors\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe ISA828 integrates quickly and seamlessly with ProTools HD, as well as other popular hard disk recorders and mixing desks.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSwitchable impedance\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eSelectable per channel; choose one of four carefully selected input impedances, including the original ISA110 setting, to suit any microphone.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDirect instrument inputs\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eEach instrument input features high and low impedance options to provide a comprehensive and accessible DI solution.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eInserting available on every channel\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAllows external devices to be inserted between the preamp and the A-D converter, using the 25-pin D-type cable.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHigh pass filter, phase reverse and phantom power\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eEach has a dedicated switch, independent on each channel.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSix LED input meter\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eComplete with precise meter trim - Designed to utilise the same reference points as Avid Pro Tools HD.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMic Input Response\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGain range: 0dB to 60dB in 10dB steps\u003c\/li\u003e\n\u003cli\u003eInput Impedance, variable: 600?, 1k4?, 2k4?, 6k8?\u003c\/li\u003e\n\u003cli\u003eEIN (equivalent input noise): -126dB measured at 60dB of gain with 150 Ohm terminating impedance and 22Hz\/22kHz bandpass filter\u003c\/li\u003e\n\u003cli\u003eNoise at main output with gain at unity (0dB): -97dBu measured with a 22Hz\/22kHz bandpass filter\u003c\/li\u003e\n\u003cli\u003eSignal to noise ratio relative to max headroom (9dBu): 106dB\u003c\/li\u003e\n\u003cli\u003eTHD at medium gain (30dB): 0.0008% measured with a 1kHz -20dBu input signal and with a 22Hz\/22kHz bandpass filter\u003c\/li\u003e\n\u003cli\u003eFrequency response at minimum gain (0dB): -0.5dB down at 10Hz and –3dB down at 110kHz\u003c\/li\u003e\n\u003cli\u003eFrequency response at maximum gain (60dB): –3dB down at 16Hz and –3dB down 85kHz\u003c\/li\u003e\n\u003cli\u003eCMRR: 91.8dB (Channel 1, 1kHz, maxiumum gain)\u003c\/li\u003e\n\u003cli\u003eCrosstalk Channel to Channel: with 10dB@1kHz input to chA, chB output =102dBrA.
