What are the input/output voltages in different modes?

Question: What is the maximum RCA input voltage that the iTube 2 can receive in default 0db buffer mode? And in 9db buffer mode?

Answer: For undistorted output, the following levels should not be exceeded.

0dB -> +20dBU (7.75V)
+9dB -> +11dBU (2.75V)

Further question: What is the maximum RCA input voltage that the iTube 2 can receive in pre-amplifier 0db mode? And in 9db pre-amplifier mode?

Answer: As there is a volume control that should be set according to the requirements of the source, there is no specific signal level on the input. It is recommended to limit the input to less than 60V AC for reasons of electrical safety.

Further question: What is the RCA output voltage in default buffer 0db mode? And in 9db buffer mode?

Answer:

0dB output voltage is input voltage.
+9dB output voltage is input voltage + 9dB (input *2.81).

Further question: What is the maximum RCA output voltage in pre-amplifier 0db mode? And in 9db pre-amplifier mode?

Answer: The maximum undistorted output voltage in all cases (pre-amplifier/buffer/0dB/9dB) is greater than +20dBU (7.75V).
