MR-PRO outputs
Both the RCA and the XLR have a balanced output impedance
of only 12.5 ohms. The level of the XLR output corresponds
closely to the set output voltage, based upon the low 12.5 ohm
output impedance of the generator.

Behavior with low-impedance loads
The maximum output current of the MR-PRO is 10 mA. If the
connected load consumes more current, the internal regulation
of the MR-PRO reduces the output level. This condition will be
indicated on the screen by the flashing output level display:

Overview
XLR short-circuit between Pin 1 and 3
Commercially available XLR to RCA adapt-
ers short-circuit the XLR Pins 1 and 3. Do
not use such adapters with the Minirator!
They will reduce the signal quality, thus use
the RCA output instead.
The MR-PRO is designed for loads down to
600 Ohm. Depending on the output level
and the output frequency, however, the
level is maintained, even for lower load im-
pedances.
Minirator -40dB Adapter
For highest quality microphone level signals
we recommend the “Minirator -40dB Atten-
uator” which is available as an accessory.
It improves the signal to noise ratio for low
level signals by 40 dB.
