T1 This information is applicable to the T1 ToneMatch® audio engine

You can use four microphones with a T1 ToneMatch Audio Engine even though there are only 3 XLR inputs. Channel 4/5 can be used if you have an impedance matching transformer. Note that if your microphone requires phantom power, then you will need to supply that too as there is no phantom power on T1 ToneMatch® Audio Engine Channel 4/5.

Condenser Microphone

The microphone shown here is a clip-on instrument microphone, but if you are using a vocal microphone the same connections would apply.

Note: the Isomax device shown below is a standalone phantom power supply. You will not need this unless your microphone requires phantom power.

Note: the phantom power supply is only required if your microphone requires phantom power (e.g. condenser microphone). Most dynamic microphones will not require you to use a phantom power supply.

T1® Channel 4/5

I had to turn the input trim higher on Channel 4/5 than when I plugged the microphone directly into Channel 1,2,3 - but it worked.

NOTE - you have to have the impedance matching transformer.
