18、 ed I nst al l at ion The ampl ifier may be mounted in a standard 19” equipment rack, by using the Bogen Model RPK53 Rack Panel Kit ( accessory; sol d separatel y) , which incl udes two brackets and the necessary hardware for instal l ation. NOTE: Befor e installing the amplifier in a r ack, install

19、 any accessor y tr ansfor mer s r equir ed. See Input Connections section. Attach one of the RPK53 brackets to each side of the unit and se- cure ( with screws provided) through the hol es on the side panel . Each bracket measures 2”W x 3- 1/ 2”H x 1”D.

I f other heat- producing equipment, or several ampl ifiers have been instal l ed in an encl osed rack or cabinet, you must ensure that there is space above and bel ow the ampl ifier( s) to al l ow for passiv

21、e cool ing. I t is recommended that the ampl ifier be instal l ed on the bottom of a rack or above any equipment that does not produce heat. Power and Grounding The three- wire AC l ine cord has a three- prong pl ug which shoul d be pl ugged into a properl y grounded, three- wire, 120V 60Hz outl et.

22、 I t is important to ground the ampl ifier. Auxil iary Power Recept acl e Caution:The fr ont panel POWER switch does not contr ol the aux- iliar y r eceptacle. The AUX POWER receptacl e on the rear panel is a three- wire grounded outl et that may be used to suppl y power to accessory equipment in th

23、e sound system. Ensure that the accessory equip- ment does not require more than 300 watts. Equipment connected to the auxil iary receptacl e wil l be grounded, provided the ampl ifier l ine cord has been properl y grounded. The outl et is protected by an internal fuse.

Connect the signal source to the BAL LO- Z terminal strip and connect the cabl e shiel d to the GND terminal . For an unbal - anced input, connect a jumper wire from

29、the GND terminal to an adjacent input terminal . I nput from Anot her Ampl ifier The BPA60 may be driven from an ampl ifier that provides a 25V or 70V constant vol tage output. Connect the output of the driver ampl ifier to one of the HI - Z input jacks via a resistor network ( see Fig. 3) . These r

30、esistors are in addition to the normal l oudspeaker l oad impedance on the output of the driver ampl ifier. Out put Connect ions Caution: Follow local electr ical codes when connecting ampli- fier output. Figure 1shows the l ocation and impedance val ues for the output terminal strip. Cl ass 2 wirin

31、g is acceptabl e for output l oads. Speakers The BPA60 features output connectors for 16- ohm,8- ohm/ 25V, 25VCT and 70V speakers. The ampl ifier provides outputs for 25V and 70V speakers. 70- vol t speaker connections are made between the 70V and COM terminal s on the output terminal strip. The COM

32、 and GND terminal s of the output terminal strip are connected using a shorting cl ip. The shorting cl ip enabl es the ampl ifier output to act as an unbal anced output ( one side of the output connected to ground) . I f desired, the output can be made to be a bal anced output with no connection to

33、ground. To bal - ance the output, simpl y remove the shorting cl ip. Al l speaker con- nections remain the same as above. 25V speaker connections are done in the same manner. Hum I f the connections between the signal sources and ampl ifier are in- correct or defective, hum- type interference may oc
