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

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.

MY CHIHUAHUA LOVES THESE BALLS!!
Color: Samll Set of 8
My little chihuahua, BamBam, is addicted to balls, especially little balls that squeak! However, any balls that have material on them, BamBam will tear them apart, swallow the material and then get an upset tummy! These balls saved the day! BamBam LOVES them & she cannot tear them apart! They hold up so well! No matter how much BamBam plays with them, they keep squeaking away!

Squeaky ball
Color: Large Set of 4
Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.
