It's capable of reaching 80W of peak power with 10W per channel. The unit's front panel sports volume controls for each channel, as well as two master volume adjustment knobs, two sets of bass and treble controls, and a power switch. The volume controls are illuminated so they can be seen and operated in darkened environments.\u003cbr\u003e\n\u003cbr\u003e\nThe amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you'll find euroblock connections for mic\/line inputs, as well as unbalanced RCA inputs, speaker connections, dip switches for input routing, and more. The unit is also equipped with two RJ45 connectors for use with JBL CSR-V in-wall volume controls (available separately).\u003cbr\u003e\n\u003cbr\u003e\nThis Commercial Series mixer\/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channels one and five, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with two auxiliary outputs, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e\u003cstrong style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003eChannel Modes\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e8 inputs with 2 outputs of 80W of power.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e\u003cstrong style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003eControls\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003eIndependent Bass and Treble controls for each output channel.\u003cbr\u003e\nInput level and output volume controls.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e\u003cstrong style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003eHi-Z Switch\u003c\/strong\u003e\u003cbr style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003e\nThe Hi-Z switch will switch in the built-in output transformer allowing the unit to drive 70V or 100V speaker systems directly when connected to the appropriate output terminals.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e\u003cstrong style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003ePhantom Power\u003c\/strong\u003e\u003cbr style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003e\nPhantom power (27 V) can be applied to all mic inputs by turning on Phantom Power within the dip switches.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"line-height: 23.1px; margin: 0px; padding: 0px; vertical-align: top; font-family: Arial; font-size: 16px; color: #000086;\"\u003e\u003cstrong style=\"margin: 0px; padding: 0px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif;\"\u003eVOX Function\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; padding: 0px 0px 15px; vertical-align: top; font-family: 'Open Sans', Arial, Tahoma, sans-serif; font-size: 13px; color: #454546; word-wrap: break-word; background-color: #ffffff;\"\u003e\u003cspan style=\"font-family: Arial; font-size: 16px; color: #000086;\"\u003eVoice activated ducking is available on input channel 1 and channel 5.

The \nlow profile depth of only 100 mm (4 in) allows the speaker to fit in locations \nwhere deeper loudspeakers do not. \u003cbr\u003e\n\u003cbr\u003e\nThis loudspeaker is designed to provide excellent performance for paging and \nlight-to-medium music in a wide variety of applications, including education \nclassrooms, business music systems, retail stores, music\/paging systems, \nairports, reception\/waiting rooms, lounges, courtrooms, meeting rooms, and more. \n\u003cbr\u003e\n\u003cbr\u003e\nThe very high sensitivity of 96 dB provides maximum sound level, even at low tap \nsettings. LCT 81C\/T contains a 200 mm (8 in) dual-cone driver with a very high \n96 dB sensitivity. The driver features a 25 mm (1 in) diameter voice coil with a \nKapton coil-former and high-temperature wire for better power dissipation and \nlong-term reliability. The speaker's built-in 10 Watt transformer provides \nversatility by allowing use on 100V or 70V distributed loudspeaker lines, as \nwell as at 8 ohms (low impedance) for driving directly from a low impedance \npower amplifier. Adjusting is convenient via a rotary switch on the side of the \nrear enclosure. Two safety seismic attachment tabs are provided for securing to \nceiling deck, plus 4 holes are provided -- one in each corner. The color of the \nperforated grille is white.\u003cbr\u003e\n \u003c\/font\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cfont size=\"5\" face=\"Arial\"\u003eFeatures:\u003c\/font\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cfont face=\"Arial\"\u003e\n\u003cul\u003e\n\t\u003cli\u003eHigh efficiency 200 mm (8 in) dual-cone driver.\u003c\/li\u003e\n\t\u003cli\u003eEasy lay-in installation into 2' x 2' US-style suspended grid ceilings.
