Product Description

Line Circle

The ultimate analog preamplifier...

Design features:
  • 2-chassis design with 1 chassis housing the power supply, digital controller circuitry, software processing & the LED display. The other chassis contains ONLY audio circuitry.
  • Power supply voltage regulation includes i 2 DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC in the audio circuit’s signal path – 40 stages in all.
  • Gain offset adjustment of ±10dB for each line input.
  • Each line input is fully configurable to be “home theater ready”, whereby the 850P’s volume control is bypassed.
Specifications: 
  • Number of inputs - XLR / RCA - 3 pairs / 5 pairs
  • Input Sensitivity - 200mV - 4.0V RMS
  • Input Impedance - 11,000Ω
  • Gain -9dB
  • Number of Outputs - XLR / RCA - 2 pairs / 2 pairs (fixed + variable)
  • Signal-to-noise Ratio (20Hz-20kHz) - 130dB @ full output
  • Frequency response - 5Hz - 100kHz ±0.1dB
  • Crosstalk @ 1kHz - -130dB
  • Output impedance - 50Ω
  • THD (20Hz - 20kHz) - 0.0005%
  • Intermodulation distortion - 0.0001%
  • Shipping weight - 151 lb / 67 kg
  • Dimensions - each chassis (w x h x d) - 18.75 x 4.0 x 16.5 in 47.6 x 10.2 x 41.9 cm

The following accessories should be included inside the box with your preamplifier:

  • AC power cable
  • FRM-3 remote control with three ‘AAA’ batteries
  • Three (3) color-coded cables to connect the preamplifier to it’s power supply/controller chassis
  • SimLink™ cable with 1/8” mini plug terminations on each end
  • Owner’s manual
  • Warranty and product registration information (USA and Canada only)
