M-audio Octane

The 8-channel Octane preamp is specifically designed to enhance the front end of any multitrack digital recording system. Its award-winning M-Audio preamp technology delivers pristine digital signals to any Lightpipe-compatible devices such as hard disk recorders and digital mixers. Octane is ideal for miking drum kits or bands—and the two mic/instrument channels are great for guitar, bass and other instruments. M-S matrix encoding lets you employ stereo miking techniques previously available only in pro studios. Octane even has analog preamp (direct) outs for each channel, making it the perfect upgrade for any digital audio interface or mixer. Word clock also means that you can sync multiple Octanes for as many channels as you need as your studio grows.

Award-winning M-Audio preamp technology 8 channels, each including:

microphone input (XLR)
line input (1/4” TRS)*
preamp out (1/4” TRS)*
3-segment LEDs
20dB pad
phantom power with indicator (groups 1-4, 5-8)
2 channels are mic/instr preamps (front-panel 1/4” TS) ADAT Lightpipe output (TOSlink)
24-bit audio resolution throughout
selectable sample rate (44.1k and 48k) and external sync
word clock I/O (75-ohm BNC) for synchronization to other digital devices
line inputs are half-normalled as insert ins or standalone A/D
M-S matrix encoding on channels 7 & 8 with width control
phase reverse switches on even channels
lowcut filter on channel 1 (-12dB/oct @ 80Hz)
* balanced/unbalanced operation
