Innovative circuit design and superb peIntroducing TOA's DA-250F and DA-250FH power amplifiers.Featuring multiple high power outputs, advanced digital technology andcompact, lightweight design, these versatile amplifiers are perfect solutions forvirtually any installed sound application.High-efficiency amplifier topology.TOA's proprietary amplifier topology achievesapproximately 85% efficiency in AC mains to output powerconversion. Thehigh-efficiency,compact designoperates at muchlower temperaturelevels eliminatingthe need for largeheat sinks.Efficiency vs OutputDA-250 Series Conventional AB-class Amplifier1009080706050403020100 20 40 60 80 100Output (%)Efficiency (%)Amplifier design optimized for installed soundapplicationsThe DA-250F and 250FH are specifically designed toproduce high power with high efficiency. Along withswitching mode power supplies, the amplifiers also offerthe high power advantages of Pulse Width Modulation(PWM) which requires much smaller power supplyvoltage than conventional amplifier designs.Two configurations suit different applications.Along with the low impedance DA-250F, a highimpedanceversion, the DA-250FH, is available for 70/100volt application.Versatile enough for any venue.Both amplifiers are well-suited for a wide variety of installedsound requirements. The DA-250FH isideal for venues ranging from exhibition halls, sportsfacilities and gymnasiums to houses of worship and meetinghalls and many other locations. The DA-250FH proves idealfor sound reinforcement in multi-zone multi-zone applicationssuch as presentation and press conference rooms as well asrestaurants and similarly sized locations.Compact dimensions facilitate installationThe powerful yet compact DA-250F and DA-250FH amplifiersoccupy only one standard rack space and weight only 6.6kg(14.6 lbs) allowing flexible installation options. For complexinstalled sound applications, amplifiers can be stackedtogether, requiring onlyone perforated airflowpanel between every 5units. The amplifiers arealso equipped with duallow-noise constant speedfans to ensure adequatecooling in demandingenvironmentsand extend operationalreliability and service life.Conventional Amp.DA-250 Series Amp."Up to 20 amplifierchannels in onlyfive rack spaces!"Easily accommodates high power requirements.Both amplifiers can be conveniently bridged* (Channels1/2 and 3/4 bridgeable), increasing the output from 250Winto 4 channels up to 500W into 2 channels.* please see specifications for all bridged power outputs for the differentamplifier configurations.
formance that satisfy any requirement.DA-250FHDA-250FEnhanced reliability for trouble-free operation.Both amplifiers have been over-engineered to provide longterm operation under demanding conditions. Fullyindependent power supplies for each of the 4 amplifierchannels enhances reliability and allows uninterruptedoperation in the event a channel should fail. This is asignificant advantage in remote installations where serviceaccess may be difficult. Each unit also incorporates TOA'sno-compromise build quality to minimize any problem aswell as comprehensive protection circuitry.4431.8465482Front ViewRear ViewComventional AmplifierPower supply from transformerDA-250 SeriesAC power supply374400Side View20PowerSupplyMT-250HMatching Transformer131Power AmplifierPower AmplifierWith built-in power supply60MAX 140Comprehensive protection circuitry.Advanced protection circuitry monitors voltage, currentand thermal levels and disables output to minimizepotential damage from overloads, short circuit, DC offsetor overheating.Control cover eliminates tampering.Each amplifier includes attenuator security covers toprevent control settings from unauthorized adjustments.Capacity:Primary impedance:MAX 800 – 250W100V line : 40Ω/66.6Ω70V line : 19.6Ω/32.6ΩSecondary impedance: 100V line : 40Ω/66.6Ω70V line : 19.6Ω/32.6Ω50V line : 10Ω/16.6ΩFrequency response: 30Hz – 18kHz (+0dB, –3dB)Connection terminal: Screw terminal (M4)Weight:3.7kg4-M4116
