1 To avoid unwanted signal noise on the RCA ports, we recommend adding no more than 12dB of gain to the
RCA port or when XLR B/RCA is used
Connecting devices that are not designed for phantom power when phantom power is enabled for
the two XLR ports can seriously damage those devices. Always check the phantom power LED
before connecting devices to the XLR ports.
