Functions
• Input and output switching: Four inputs and outputs can be switched independently.
• Volume control: A balance function can be implemented by controlling the left and right levels independently.
Each channel can be set to 0 to –20 dB in 2 dB steps, –20 to –32 dB in 3 dB steps, –32 to –52 dB in 4 dB steps, –52 dB...
