5 Specification
Max. o/p level (MOL): +19dB into 600Ω
+24dB into 10kΩ
Max gain: 30dB.
THD (at no compression): better than 0.06 % @ 100Hz &
1kHz
Noise, IEC weighted: better than 100dB below MOL.
Input impedance: 15kΩ.
Frequency response: <1dB variation over range of
12Hz to 56kHz.
Attack time: 0.004s to 0.12s
Release time: 0.04s to 2.4s
Output impedance: 600Ω
Distortion will increase with compression, typically 0.2% &
0.25% at 1kHz & 100Hz with 8dB compression. Attack and
release controls are somewhat interdependent, for instance
a change of attack setting may affect the release time
slightly. Therefore, no times are given on the front panel.
VALVE COMPLEMENT (2 ea):
Input/Compression: PCC85 (equiv. 9AQ8)
Output: ECC81 (equiv. 12AT7, CV4024)
Side chain detector: EB91 (equiv. 6AL5, CV4025).
