Specifications for FREQue II
Spectral Controls on MUSIC input
Weight Bass filter (shelving) ±12dB gain from around 80Hz@6dB/8ve
Edge Treble filter (shelving) ±12dB gain from around
8kHz@6dB/8ve
Switch Pressed in this activates Spectral Controls
Inputs
Connectors ¼” jack, three pole, Tip /in phase, Ring cold/reverse phase ,sleeve 0V
Levels Optimum results occur with input levels of +2dBu to +12dBu,
maximum input level > +12dBu
Freq Response Music inputs <20Hz to >35 kHz, modulator input DC to
>35kHz
Input Impedance >10k
MOD Module8ion Input - this feeds one side of Ring Mod
MUSIC Main Input - this feeds the other side of Ring Modulator if
spectral controls are activated they vary the spectrum of this
input.
Breakthrough MOD in +10dBm with no MUSIC signal, MOD out <-65dBm
maximum, typically <-70dBm, same for MUSIC signal with no
MOD.
Outputs
Connectors ¼” jack, three pole, as above
OSC Oscillator output at ca +12dBu
Levels For input levels of +4dBu to +12dBu output will be around²
+4dBu - +12dBu, maximum output level around 65kHz
Freq Response Flat from DC to a -3dB point at around 65kHz
Signal to noise -82dB (equivalent to a good mic set to medium gain)
OSC
Fine Varies around centre frequency by ca 5%
Tune Varies centre frequency over selected range
Range Selects from 4 ranges - [0.2Hz-9Hz, 2Hz-90Hz, 20Hz-900Hz and
380Hz-11kHz]
CV Inputs CV Inputs to each oscillator on ¼” jacks (unbalanced), 0-15V,
V/Hz characteristics
OSC Outs Output for both oscillators @ +12dBu
² The modulation process involves the interaction of both inputs, and as such it is impossible to predict
exact output levels
