TP-Link RX-7-248 - Manual (Page 3)

Precautions
1. Power Supply Unit (RPS-7)
The RPS-7 is separate from the console.
If the power switch on the RPS-7 is turned "on" without a connection between the
RPS-7 and the board using the accessory cable packed in the RPS-7, power is not
supplied to the board. The power switch must be "on" after the connection is made.
2. Power Supply
The RPS-7 is designed to operate on local AC (50/60Hz) mains, ±10%.
3. Fuse Replacement
The front panel of the RPS-7 is provided with a fuse holder for the AC line. Replace
only with the Identical Type and Value Fuse.
4. XLR (Cannon) Connector
The connectors are wired in such a manner that pin 1 is ground (shield), pin 2 is cold
(low, minus), and pin 3 is hot (high, plus).
5. Phantom Power Supply
Each RX-7 incorporates a 48V DC Phantom Power circuit. If phantom power is
required, the phantom power Master Switch on the rear panel of the Power Supply
Module should be "on", and the phantom power switch on the front panel of each
Input Module for which phantom power is required should be "on". When using
phantom power, avoid connecting unbalanced microphones or connecting other
equipment for which the output transformer center tap is grounded.
