Focusrite ISA 428 4-Channel Microphone Preamp #OJ04616 (Used)

The Focusrite ISA 428 Four Channel Mic Preamp is a modern classic with the stamp of Rupert Neve! It features four ISA-series transformer-based preamps. The benefits of Focusrite's classic preamp topology include superb common-mode rejection, an excellent overload margin, an extremely low noise floor and super-wide bandwidth. Switchable insert points are also featured on every channel, allowing routing (between preamp and output) to additional external processing.

FEATURES:

• Accurate 'moving coil' peak meters provide clear metering designed to catch even the fastest and most elusive of transients
• Four front panel instrument inputs give instant access on the front fascia and no separate DI box required
• Four additional AD converter inputs combine with the four preamp inputs to provide eight line inputs, routable discretely to the eight-channel AD converter option
• Focusrite's custom optical design protects the AD converter by preventing 'digital overload' (requires that an -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 - the same filter as featured on the original ISA110 and the Focusrite forte console
