รหัสสินค้า: 001714

รายละเอียด: Key Features
- Four ISA-series transformer-based pre-amps
The benefits of Focusrite’s classic pre-amp topology include superb common-mode rejection, an excellent overload margin, an extremely low noise floor and super-wide bandwidth.
- Dedicated analogue insert points
Switchable insert points are also featured on every channel, allowing routing (between pre-amp and output) to additional external processing.
- Accurate ‘moving coil’ peak meters
Clear metering designed to catch even the fastest and most elusive of transients.
- Four front panel instrument inputs
Instant access on the front fascia and no separate DI box required.
- Eight line inputs
Four additional A-D converter inputs combine with the four pre-amp inputs to provide eight line inputs, routable discretely to the eight-channel A-D converter option.
- Eight Channel optional 192kHz A/D conversion card
With the additional four ADC inputs, two ISA428’s can be used with a single ADC, providing eight channels of pre-amplification, A-D conversion and VU metering.
- Custom Global A-D converter ‘soft clip’ limiter
Focusrite’s custom optical design protects the A-D converter by preventing ‘digital overload’. It requires that an A-D converter be installed.
- Switchable Impedance
Ideal for mic matching or extended microphone creativity. Settings include the ‘Vintage ISA110’ setting, providing the original Focusrite signature sound.
- Variable Focusrite high pass filter
Provided on every channel, this is the same filter as featured on the original ISA110 and the Focusrite forte console.
