Question about RØDE Ai-1

Hi LuckyFelix,
The internal impedance at the headphone output of the AI-1 cannot be read directly from the technical specifications in the "User Guide". But it is still possible to draw 24mW with 32-ohm headphones and 245mW with 300-ohm headphones at a THD of 1%. I use the AI-1 with a Beyerdynamic DT 1770 Pro (250 ohms). This high-impedance load is no problem for the headphone amplifier - I don't even need to turn it up to a third of the maximum volume!
Greetings, Kurt
