Qituo ar64 can convert signals from Madi format to adat format, or adat format to Madi format. All 64 channel Madi input / output can be converted to the corresponding 8-channel adat Optical Toslink input and output signal ar0808 interface box. In addition, ar64 has a very easy-to-use 64 x 64 channel matrix router based on 8 channels. Any input assigned to the 8-channel interface box can be sent to any 8-channel output ar0808 interface box for switching.
