I'm trying right now the new 664, and I'm trying to find a fault in the machine, but for now the only weak point is the internal power supply (5 AA battery), but to be honest it is also stated in the manual that the power internal power supply is to be considered as a buffer.
The device is very light, very intuitive and fast in the input settings.
With a lipo battery 2600 mAh 14.8 V, recording with one microphone with phantom power and 5 line channels and a receiver Lectro sra powered by the battery, has been on for about 6 hours, not bad!
Very fast to change the name's take.
Useful the short key to increase the number scene ( like a 788t )
very defined and well-illuminated display, visible also in critical condition
Than the Nomad that I had the chance to try, it seems to me a very reliable machine, in the best tradition of sound devices.
One thing that is not very clear in the specifications and in the manual :
- With the two cards inserted the device records simultaneously on both boards, creating a backup, (( cool )
