Thank you for viewing. This is a YAMAHA digital stage box, the Tio1608-D. I purchased it used on Mercari about three years ago. About a year ago, there was a problem with the secondary port, so I had YAMAHA replace the parts and check the operation. I am selling it because I am replacing my system. * 48kHz * 16in 8out This is the model one generation before the current Tio1608-D2. The current model supports 96kHz, but this one is fixed at 48kHz. Other than the sampling rate, there is no major difference from the current model. For the listing, I connected it to a TF and another Tio1608-D using Quick Config, and confirmed the operation by connecting both primary and secondary ports in a daisy chain. The inputs are XLR and TRS combo jacks, which are easy to use. I checked all channels by connecting condenser microphones and confirmed that there were no problems. The outputs are also problem-free. Please note that I have not performed strict checks using measuring instruments. There is rust on the screws and rack ears from the time of purchase. There are also other paint剥がれ (peeling). The contacts have been polished with Caig DeoxIT Red. Power cable included. Shipped via Mercari delivery service. The following is a reprint: Plug In & Play Dante Stagebox Solution The Tio1608-D is an I/O rack with 16 microphone/line inputs and 8 line outputs that supports the advanced audio network standard "Dante". By simply connecting the Tio1608-D installed on the stage and the TF series main unit equipped with the Dante input/output card NY64-D with an Ethernet cable, high-quality/low-latency audio transmission is possible. The preamplifier gain on the Tio1608-D can be remotely controlled from the TF series main unit, and can be controlled in the same way as the preamplifier built into the main unit. *HA control of the Tio1608-D can only be performed on the Primary line. Even when using the TF series or CL/QL series, HA control cannot be performed using the Secondary line during redundant connection.
