Electrocompaniet EC4.7 (issue 3) - Manual (Page 6)

Technical specifications EC 4.7
The following technical data were measured on randomized test objects and are typical data.
All measurements are made at 120V / 240V // 50Hz / 60Hz
Clipping point of the preamplifier is set to a level where total harmonic distortion (THD) is 0.2 %.
Measurements Parameters Single ended Balanced
Input impedance (Fixed) 330 Kohm 165 Kohm
Input level (RMS) > 10 V > 20 V
Equivalent input noise
< 3 mV
Signal to noise (400 - 30 KHz) > 100 dB
Channel separation (20 - 20KHz) > 90 dB
Frequency response (DC-65 KHz) - 0.4 dB
Gain (Maximum volume) 0 dB 6 dB
Attenuation
(Minimum volume) - 75 dB
Output Impedance (Fixed) 100 ohm
Output level
(RMS) > 8 V > 16 V
THD (1 V in, 1 V out, 1 KHz) < 0,001 % < 0.0005 %
Output noise (400 – 30 KHz) < 5 mV < 10 mV
Rated output level
10 % change in line voltage will give approximately 10 % change in output level.
Power consumption (no load or signal) 15 W
The EC 4.7 is DC coupled from input to output.
