Notes
- The rear has two rows of connectors; order counts left to right by position, so close neighbours may be read either way.
- The four 3.5 mm audio inputs are numbered left to right; their printed labels are source names.
- The rack adapter is named RK-1 in most places and RK-T2B in one.
What the manufacturer doesn't say
- No PoE standard or class for the power it sends over HDBaseT (up to 13 W).
- No consumption figure; power is given as 48 V DC, 850 mA (about 41 W).
