4. INSTALLATION Rack Mounting The Phonic ZX2 and ZX4 zone mixers are standard 1 RU rack mountable mixers An additional 4 of depth are needed behind the mixer to allow room for the back panel connectors To avoid overheating be sure that there is enough air space around the unit for cooling and do not place the mixer in contact with or directly on top of high temperature devices such as power amplifiers Connectors ZX2 and ZX4 zone mixers use balanced XLR jacks for paging microphone input unbalanced stereo RCA jacks for music inputs and balanced 1 4 phone jacks for emergency audio input zone output and utility output RJ45 jacks provide input and output for paging and remote level control while an RS 232 D type 9 pin connector is provided for source link Impedance The microphone input impedance is less than 2k ohms The outputs of the ZX2 and ZX4 are electronically balanced with output impedance lower than 120 ohms When driving transformer coupled loads it may be necessary to create 600 ohms source impedance For this purpose install two 247 ohms resistors in series with pin 2 and 3 Mains Connection The ZX2 and ZX4 use a standard IEC receptacle and a universal mains cable to make the AC mains connection Make sure all units in the sound system are well grounded For your own safety do not remove the ground connection within the units or at the supply cable or fail to make this connection at all The audio ground is capaci
