Features

■

Fast data transfer via mLAN

Connecting the i88X to a computer and other mLAN devices via IEEE1394 (FireWire/i.LINK) cables
enables you to transfer multi-channel audio data and multi-port MIDI signals to and from a com-
puter-based DAW (Digital Audio Workstation) and connected mLAN devices (at a transfer rate of
400Mbps [S400]).

■

Up to 18 audio channel I/O

•

The i88X features two MIC/LINE inputs and six LINE inputs. Inputs 1 and 2 feature two sonically
transparent mic preamps (derived from DM2000) and phantom power, and accept both XLR
and TRS phone plugs. Inputs 3-8 accept TRS phone plugs (pages 8 and 11).
•
Input 1 also features a HI-Z (high impedance) jack to connect high-impedance instruments, such
as guitar or bass (page 8).
•
The Insert I/O jacks enable you to connect an external effects processor (page 11).
•
The i88X also features a sampling rate converter that supports sampling frequencies from
44.1 kHz through 96 kHz. It also features coaxial DIGITAL STEREO IN and OUT jacks and the
optical IN and OUT jacks that are switchable between STEREO and ADAT.
•
The MIDI IN and OUT ports enable you to connect external MIDI devices in the mLAN system
(page 11).
•
The i88X can process up to 18-channel input and output data when running at a sampling fre-
quency of 48 kHz or 44.1 kHz, and up to 14-channel input and output data when running at a
sampling frequency of 96 kHz or 88.2 kHz.
■
Audio Characteristics
•
Compatible sampling frequencies: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz
•
Linear 24-bit, 128-times (at a sampling frequency of 48 kHz or 44.1 kHz) or 64-times (at a sam-
pling frequency of 96 kHz or 88.2 kHz) oversampling A/D and D/A converters
•
Frequency response: 20 Hz – 20 kHz, Standard dynamic range: 110 dB
■
Direct Monitoring Function
•
Enables you to monitor the sound being recorded to the DAW without latency (sound delay)
(page 17).
■
Integrated Package Containing Plug-in Effects
•
Four VST/AU plug-in effects, including equalizer, vocal and mastering effects, etc.
