MIC 2 – 6 connections Microphones equipped with either an XLR connector or a phone plug can be used with microphone inputs 2 – 6. • Balanced or unbalanced microphones can be connected to the phone jack. • Switching ON the phantom power switch supplies power to all MIC 2 – 6 XLR connectors. •...
9.2. External Auxiliary Equipment Connections 9.2.1. AUX 1 input jack connections Two input signals can be mixed within the unit. For stereo sound source wiring, connect to both RCA pin jacks. For monaural sound source wiring, connect to either jack. To external auxiliary equipment 9.2.2.
9.5. External Speaker Processor Connections TOA's DP-SP3 Digital Speaker Processor can be used as an external speaker processor without using the unit's internal speaker equalizer function (see p. 21). The external speaker processor can also be used for either the ROOM or OUTSIDE speakers.
100 V line speakers are connected to each speaker terminal and the total wattage is less than 240 W. • The unit can produce optimum sound quality conditions when the following TOA speakers are connected and the speaker equalizer function is used. (see p. 21.)
Do not connect any other equipment than the RC-03 Remote Controller CAUTION to the MX-6224D’s Remote controller connection port. If other equipment, such as a PC, hub or network device, is connected to that port, the connected equipment could be damaged.
