"features": [
{
"feature": "Class D Amplifier\nBased on crown's proprietary and patented drivecore technology, these amplifiers are the next generation of pwm technology using cutting edge class d amplifier topologies"
},
{
"feature": "True Rack Density\nTrue rack density – 4 channel by 300w. other amplifer options available with 300w or 600w in 2/4/8 channel configurations and 1250w in 2/4 channel configurations with bridgable outputs of 300- 2500w, all in a 2u form factor."
},
{
"feature": "Direct Drive Constant Voltage\nSave money by using smaller gauge wiring to drive the speakers using either 70v rms or 100vrms. with no need for a step-up transformer at the output, the dci produces higher audio quality much more efficiently."
},
{
"feature": "CHANNEL INDEPENDENT HI-Z/LOW-Z SELECTION\nDrive either one or two speakers in low-z mode, or literally hundreds of speakers in high-z mode (70vrms or 100vrms). this means better design flexibility since dci powers all loads on a channel-by-channel basis."
},
{
"feature": "BRIDGEABLE CHANNEL PAIRS\nDci series channels are bridgeable – even in 100vrms mode – which means even more adaptability for higher power applications such as subwoofers."
},
{
"feature": "Powersave\nPowersave includes an auto-standby mode where after 30 minutes of no audio input, the amplifier powers down and consumes less than 1w; this feature can be enabled and disabled via the back panel dip switches"
},
{
"feature": "Advanced PFC Universal Power Supply\nProvides market-leading efficency, and is designed to deliver maximum power no matter where the amplifier is located; universal ac input accepts 100 – 240vac, 50/60hz (±10%)"
},
{
"feature": "REMOTE ON/OFF INTERFACE\nAux port provides additional flexibility for amplifiers to be integrated in control systems for remote on/off and amplifier fault monitoring"
},
{
"feature": "Efficien Cooling System\nHighly efficient internal cooling fans provide airflow to the most heat-generating parts. incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise."
},
{
"feature": "Analog I/O\n4x block 6-pin balanced input/4x barrier strip 4-pin output"
