Specifications
The correlation between published specifications and sonic quality is unreliable. A list of
numbers reveals virtually nothing. All technical measurements must be subject to quali-
tative as well as quantitative interpretation. Measurements of the Nº383 yield excellent
results by any standards. However, only those specifications that apply to its actual op-
eration are included here.
■ Power output: 100 watts per channel at 8Ω
200 watts per channel at 4Ω
the above power ratings measured from
20 Hz–20 kHz with no more than 0.3% THD
■ Frequency response: within 0.1 dB from 20 Hz to 20 kHz
■ Audio Inputs: two pairs balanced on XLR
three pairs single-ended on Madrigal RCA
■ Audio Outputs: one pair Madrigal-designed speaker binding posts
one pair record outputs on Madrigal RCA
■ Other Connectors: one IEC AC mains receptacle

(with slowly increasing step size at progressively lower levels)
■ Input overload:
when gain is set to +18 dB: 2V on XLR, 1V on RCA
when gain is set to +12 dB: 4V on XLR, 2V on RCA
when gain is set to +6 dB: 8V on XLR, 4V on RCA
when gain is set to 0 dB: 16V on XLR, 8V on RCA
■ Input impedance: 100kΩ
■ Output impedance: less than 0.05Ω, 20–20,000 Hz
