16RAVE 81This model features eight AES3 input channels, a total of 16 audio channels. The AES3 inputs are labeled 1 through8 on the rear of the unit.RAVE 80This model features eight AES3 output channels, a total of 16 audio output channels. The AES3 outputs are labeled1 through 8 on the rear of the unit.AC POWERA RAVE unit will operate on line voltages from 90 to 264 VAC, 47 to 63Hz. No user selection of line voltage orfrequency is required; the internal power supply automatically switches accordingly. The detachable AC powercord connects to the chassis at the IEC connector.• To replace a fuse, first detach the AC power cord fromthe RAVE unit.• Then use a flat-blade screwdriver to pry the fuseholderout, as shown at left.The fuses are held in the round openings in the end of thefuseholder as shown at right. Replace one or both fuses with thesame type: 20 × 5 mm, 2 amp, 250V.SYNC OUTPUTAt this BNC jack the RAVE unit produces a 5 Vp-p sample rate clock whenever the unit is connected to the networkand is operating properly. This clock signal can be used to synchronize external digital audio equipment, and itcoincides with the clock signal broadcast over the network. No clock signal is produced if the unit is unable tosend or receive any audio channels, or if a fault occurs with the unit. The latter occurrence will be indicated bythe Fault LED.The IEC connector contains a line filter to minimize susceptibility to RF and EMI from the AC line, and to reducedigital noise that may otherwise get out of the RAVE unit and onto the AC system. The fuse holder is an integralpart of the IEC connector, too. It contains two fuses.Use only a power source with a protective earth ground.Utiliser une source d'alimentation électrique avec mise à la terre.A RAVE unit has no power switch; the AC disconnect device is the detachable power cord.Les unités RAVE n'ont pas d'interrupteur marche/arrêt; le cordon d'alimentation détachable sert àdébrancher l'unité de la source de courant.Replace only with the same type fuse.Remplacer avec un fusible de même type.2A 250V20 × 5 mm FUSE(2 required)
