{"product_id":"dynaudio-da40-nd","title":"Dynaudio Delta 40 Four-Channel Power Amplifier (120V)","description":"\u003cp\u003eThe Dynaudio Delta 40 is a four-channel 2U power amplifier for studios and installations that handle processing elsewhere and need clean power for passive monitors. It delivers 1000 W per channel into 4 ohms, or 2400 W from a bridged pair, with THD below 0.18% at 1 kHz. Setup stays simple, with four balanced XLR inputs, a level control for each channel on the front panel and speakON outputs on the back. This is the 120 V model.\u003c\/p\u003e\n\n\u003ch3\u003eWorking with Delta DSP\u003c\/h3\u003e\n\u003cp\u003eThe Delta 40 has no onboard processing of its own. A Delta DSP amplifier can feed it processed signal from its four auxiliary outputs, so one DSP model runs crossovers and EQ for a stereo four-way system. With the optional Dante card fitted, a rear-panel switch moves all four channels from the XLR inputs to the network, with 24-bit\/96 kHz conversion.\u003c\/p\u003e\n\n\u003ch3\u003eProtection and Backup\u003c\/h3\u003e\n\u003cp\u003eEvery channel has a limiter, and the amplifier protects itself and the speakers against short circuits, DC and overheating. Depending on the fault, protection mutes all four channels or one channel pair. A short circuit on an output mutes only its own pair, 1+2 or 3+4, and the other two channels keep playing. Speaker backup inputs connect a second amplifier that switches into circuit if the main one loses power or goes into protection.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour channels, 1000 W per channel into 4 ohms\u003c\/li\u003e\n  \u003cli\u003eChannel pairs 1+2 and 3+4 bridge for 2400 W into 4 ohms\u003c\/li\u003e\n  \u003cli\u003eFour balanced XLR inputs with rear-panel link switches\u003c\/li\u003e\n  \u003cli\u003eRear-panel source switch for analog or Dante network audio (the Dante card is an option)\u003c\/li\u003e\n  \u003cli\u003eLevel control and signal meter with limit indicator on each channel\u003c\/li\u003e\n  \u003cli\u003espeakON outputs, with the channel 1 and 3 sockets also carrying channels 2 and 4 for bi-amping or bridging over one NL4 cable\u003c\/li\u003e\n  \u003cli\u003eSpeaker backup inputs for a redundant backup amplifier\u003c\/li\u003e\n  \u003cli\u003eStandby mode powers down the amplifier channels\u003c\/li\u003e\n  \u003cli\u003eLimiters, short-circuit, DC and thermal protection, and mains inrush control\u003c\/li\u003e\n  \u003cli\u003eVariable-speed fans with front-to-rear airflow and a cleanable front filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput power per channel:\u003c\/strong\u003e 500 W at 8 ohms, 1000 W at 4 ohms, 1400 W at 2.7 ohms, 1200 W at 2 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput power, bridged:\u003c\/strong\u003e 2000 W at 8 ohms, 2400 W at 4 ohms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum load:\u003c\/strong\u003e 2 ohms with reduced output (4 ohms bridged)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTHD (1 dB below maximum output):\u003c\/strong\u003e below 0.18% at 1 kHz, below 0.2% from 20 Hz to 20 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 20 Hz to 20 kHz (+0\/-0.5 dB)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 32 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity for maximum power:\u003c\/strong\u003e 6.2 dBu\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 20 kilohms, active balanced\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput CMRR:\u003c\/strong\u003e above 60 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamping factor:\u003c\/strong\u003e above 400 (1 kHz, 8 ohms)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 4 x balanced XLR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 4 x Neutrik speakON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent draw:\u003c\/strong\u003e 6.0 A nominal at 120 V into 4 ohms, below 5 W in standby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMains:\u003c\/strong\u003e 120 V, powerCON inlet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRack size:\u003c\/strong\u003e 2U, 19 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (H x W x D):\u003c\/strong\u003e 88 x 482 x 428 mm (3.5 x 19.0 x 16.9 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 10.0 kg (22.0 lbs)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShipping weight:\u003c\/strong\u003e 12.0 kg (26.5 lbs)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dynaudio","offers":[{"title":"Default Title","offer_id":67380144406777,"sku":"DA40-ND","price":7549.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0746\/5766\/1177\/files\/dynaudio-da40-nd-1-front.jpg?v=1792175631","url":"https:\/\/blackoutaudio.com\/products\/dynaudio-da40-nd","provider":"Blackout Audio","version":"1.0","type":"link"}
