iD73+ is a microphone preamplifier. It was inspired by a popular vintage British class-A mic preamplifier. Like in the original design, iD73+ module has two input transformers – one for a microphone input, another for a line input. We added DI input which can be routed to any of the module inputs (both mic and line). This gives you different tonal colors for your DI sound signal.
There are additional options for microphone input: "PAD" (reduces the input signal by 20dB) and "LoZ" (this lowers input impedance which leads to input level increase and may change the tone a bit). There is an output level control ("TRIM") and a polarity switch.
