Frequency response |
High Level Section: ±.5dB,
5 Hz to 50 kHz, - 3dB points below 1 Hz and above 200kHz. |
|
|
Phono: ±.3dB of RIAA, 30Hz
to 40kHz. |
|
Distortion (THD) |
Less than 0.1% at 2V RMS
output. (Typically less than 0.005% in midband)
(SP-9: < .01% @ 2V RMS output 10Hz to 30kHz ) |
|
Noise & hum |
High Level: (1) 70 µV RMS
maximum residual unweighted wideband noise at main output with
gain control minimum (98 dB below 5V RMS output). (2) More than
100dB below 1 V RMS input (less than 7µV equivalent input noise)
(SP-9: Phono IHF weighted 72 dB below 1 mV input) |
|
|
Phono: 0.12 µV equivalent
input noise; IHF weighted, shorted input (78dB below 1 mV
input). |
