There was a mistake on the HB website ... instead of 34 Channel the ONIX Series will feature a 48 Channel just like the AS GRP and AS GPS HS Receivers.

Plus the Internal Receiver in the 9 Series models 859, 899, 959, 999, 1159 and 1199 is a 56 Channel Receiver

Plus the 300 and 600 Series feature the same Internal 56 Channel Receiver.
