Good to know
- Battery life depends on headphones, volume and battery type – Cranborne measured about 10 hours in Low Power mode at full volume with ATH-M50x headphones.
- For best crosstalk, Cranborne recommends Cat 6 or Cat 7 shielded cable.
- The low-battery light comes on at 6.8V.
FAQ
Can I use it without other Cranborne gear?
Yes. Set Source to standalone and feed the inputs from any interface or mixer, then plug in your headphones.
Will it drive 600 Ohm headphones?
Yes. In High Power mode it gives 252 mW per side into 600 Ohm.
