S1 Pro System with Impedance Matching Transformer
With some microphones, it is possible to use an impedance matching transformer with a microphone, but Bose recommends that you do NOT attach adapters like this directly to the inputs of the S1 Pro. Using adapters increases the risk of damage to the input jacks by adding weight and stress on the input jacks.
- Bose recommends against using adapters and impedance matching transformers connected directly to the input jacks of the S1 Pro System.
You may get higher volume at a lower volume setting, you can get the same result by turning up the volume control. Using the impedance matching transformer does not raise the maximum volume available from the S1 Pro.
