NuForce Reference 18

•Configuration: Mono Input: RCA and true balance XLR  •Power output (see Power FAQ) Power/Load8 ohm4 ohm2 ohm Peak Power (20 msec hold time)325W650W 1300W RMS Power175W335W335W  *RMS power denotes maximum continuous power. Peak power denotes an instantaneous power boost. Note that typical listening normally requires about 15W of power. These high power amplifiers provide more than sufficient power for just about any speakers on the market. •Frequency Response: 20 Hz -0.3 dB - 120 kHz -3 dB •THD+N = 0.01%, 1kHz, 1W to 10W, A Weighted. •Input impedance: 22K ohm •Input sensitivity = 252mV, 1W @ 8 Ohm; 2.57V, 100W @ 8 Ohm; 1.81V, 100W @ 4 Ohm •Input sensitivity for maximum power: 3.33V •Gain: 21 db  •SNR > 100 db at 100W •12V DC Trigger Input •WBT binding post for spade and banana plug  •Chassis is made of high-grade anodized brushed aluminum to reduce audio resonance •Dimension: 17"x 15" x 2.95" •Worldwide AC voltage (84VAC to 264VAC). No need for AC regulator if the AC voltage falls within the specified range.  •Weight: 16 pounds •AC Fuse: Slow blow, 5A, 250VAC •Configuration: Mono Input: RCA and true balance XLR  •Power output (see Power FAQ) Power/Load8 ohm4 ohm2 ohm Peak Power (20 msec hold time)325W650W 1300W RMS Power175W335W335W    *RMS power denotes maximum continuous power.
