It delivers 550 W x 4 channels (4 ohm output) using a switching power supply. Each channel is equipped with an independent power section. Its Control\/Monitor terminals permit power ON\/OFF control of the individual channels and status monitoring for the power ON\/OFF on each channel, protection on each channel, and fan operation. Prepare the control panel or status monitor display panel separately. It can be mounted in an EIA Standard equipment rack (2 unit size).\u003c\/span\u003e\u003c\/p\u003e\r\n\u003ctable id=\"spectable\"\u003e\u003ccaption\u003eSpecification\u003c\/caption\u003e\u003c\/table\u003e\r\n\u003cdl\u003e\u003cdd\u003e*0 dB = 0.775 V\u003c\/dd\u003e\u003c\/dl\u003e\r\n\u003ctable id=\"spectable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\r\n\u003ctd\u003e120 V AC, 50\/60 Hz\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eAmplification System\u003c\/th\u003e\r\n\u003ctd\u003eClass D\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003ePower Consumption\u003c\/th\u003e\r\n\u003ctd\u003e480 W (based on UL\/CSA standards), 2800 W (rated output 4 Ω), 1650 W (rated output 8 Ω)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eInput\u003c\/th\u003e\r\n\u003ctd\u003e4 circuits, +4 dB* (1.23 V) (input level control in maximum position),\u003cbr\u003e10 kΩ, electronically-balanced, removable terminal block (3 pins), XLR-3-31 type connector\u003cbr\u003eCH 1 mode ON\/OFF switch (ON: CH 1 to All ch, OFF: Each ch)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eRated Output\u003c\/th\u003e\r\n\u003ctd\u003e4 channels: 550 W × 4 (4 Ω), 350 W × 4 (8 Ω)\u003cbr\u003e2 channels (BRIDGE): 1100 W × 2 (8 Ω)\u003cbr\u003eM4 screw terminal, distance between barriers: 8.8 mm (0.35\")\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eFrequency Response\u003c\/th\u003e\r\n\u003ctd\u003e20 - 20,000 Hz (-2 dB, +1 dB)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eTotal Harmonic Distortion\u003c\/th\u003e\r\n\u003ctd\u003e0.1% (1 kHz)\u003cbr\u003e0.15% (20 - 20,000 Hz)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eProtection Circuit\u003c\/th\u003e\r\n\u003ctd\u003eProtection against excessive current flow due to overload, short circuit,\u003cbr\u003eunusual DC voltage output, temperature rise at power amp. heat sink (100℃ or more (212゜F)),\u003cbr\u003etemperature rise at power supply heat sink (80℃ or more (176゜F))\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eS\/N Ratio\u003c\/th\u003e\r\n\u003ctd\u003e100 dB (A-weighted)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eCrosstalk\u003c\/th\u003e\r\n\u003ctd\u003e70 dB (A-weighted)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eControl\/Monitor\u003c\/th\u003e\r\n\u003ctd\u003eControl input: Power ON\/OFF status of the individual channels\u003cbr\u003ephotocoupler input, drive voltage: 9 V DC (Min) - 14 V (Max), 12 V (Typ)\u003cbr\u003eMonitor output: Power ON\/OFF status of the individual channels, Protection status of\u003cbr\u003ethe individual channels, Fan operation status\u003cbr\u003ephotocoupler open collector output, withstand voltage: 30 V DC,\u003cbr\u003econtrol current: Under 12 mA\u003cbr\u003eConnector: RJ-45 connector × 2\u003cbr\u003eConnection cable: Category 5 twisted pair cable for LAN (CAT5-UTP)\u003cbr\u003eMaximum cable distance: 600 m (656.17 yd)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eLED Indicator\u003c\/th\u003e\r\n\u003ctd\u003ePower (blue) × 1, Input (green) × 4, Output (yellow) × 4, Peak (red) × 4, Protect (red) × 4\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eCooling\u003c\/th\u003e\r\n\u003ctd\u003eForced air cooling\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eOperating Temperature\u003c\/th\u003e\r\n\u003ctd\u003e-10℃ to +40℃ (14゜F to 104゜F)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eOperating Humidity\u003c\/th\u003e\r\n\u003ctd\u003e90% RH or less (no condensation)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\r\n\u003ctd\u003ePanel: Aluminum, black, alumite Case: Plated steel sheet\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\r\n\u003ctd\u003e482 (W) × 88.4 (H) × 404.2 (D) mm (18.98\" × 3.48\" × 15.91\")\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\r\n\u003ctd\u003e8.8 kg (19.4 lb)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\n\u003cth\u003eAccessory\u003c\/th\u003e\r\n\u003ctd\u003eRemovable terminal plug (3 pins) …4, Tamper-proof cap …4\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e","brand":"TOA","offers":[{"title":"Default Title","offer_id":43138995748912,"sku":"TO-DA-550F CU A00","price":3916.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/8280\/2480\/files\/da-500f-hl_front_and_back_web_1.jpg?v=1780054662","url":"https:\/\/avguys.ca\/products\/digital-multi-channel-amplifier-550w-x-4-channels-4-ohms","provider":"The AV Guys","version":"1.0","type":"link"}
