The Grace Design m108 is a rack-mountable eight-channel preamplifier and ADC providing connection points for eight microphones on the rear panel, as well as two Hi-Z instrument inputs on the front. With this unit, you can either achieve analog amplification through its transformerless, transimpedance design, or utilize its on-board conversion stages to route signal into your DAW in a variety of digital output formats, including AES, ADAT, and USB. The unit is also remote-controllable, able to receive commands from Grace's m802 remote control unit or Pro Tools via on-board 485/422 serial / MIDI ports.

Its push-button rotary knob handles the navigating and instantiation of various operations, though dedicated push-buttons are assigned for essential needs, such as 48V phantom power switching, phase reversal, channel grouping, and clearing peaks on the meter. A headphone output with integrated headphone amplifier allows for low-latency monitoring of assignable channel pairs, or for listening to USB playback from a source-computer.

The m108 features word clock I/Os and optional expansion slots to interface with Dante networks. Furthermore, this device is compatible with m802s, so you integrate this unit into any existing m802 system

Monster cable
Size: 4/0AWG, Color: 3ft Black + 3ft Red
Well I now know what 4/0 or 0000 cable is. Huge but very easy to handle or bend to shape.

bought twice to make custom UPS setup battery leads, not disappointed
Color: Black, Size: 25-Feet
bought this item(25ft 2awg) twice, the first time I did was to create some quick connect cables between my batteries and my distribution block to my 4kw invertor(24v 165a peak calculated load) I may have oversized due to knowing that the bigger you go the less you stress components and loose power to voltage drop these cables are a nice high-grade rubber jacket and the 30awg strands are ideal for maximum flexibility while remaining fairly easy to terminate this cable also includes a backer paper wrap that allows for easy stripping(of the rubber) without too much strand loss damage(from cutting too close to the core) overall, would buy again, like I did, if I need larger runs(say for feeding an RV solar AC distribution panel) I would buy this brand again, in the 100ft range or so THHN is not ideal for flex connections(strands are way too stiff) but a couple runs of welding cable like this inside something like "smurf tube" would be a perfect high-power temporary connection system, or just a way to isolate a large battery stack used for a solar setup in fact I may do that someday, set up a pallet of LiFePO4 batteries with a large quick connect, and just recharge the massive array(s) at a secondary location where solar is more ideal(or other renewables)
