Page 15: Inputs And Outputs
. NOTE: Although the range of CV modulation is ±5V, the CV inputs accept voltages up to ±10V. Any voltages above or below 5V are simply clipped at ±5V. Use Quadrax’s internal attenuverters (as described in Programming the CV Matrix ) to dial down the input voltages. -

Page 19: Channel Link Options
Channel Link Options Though it’s perfectly acceptable to think of Quadrax as four completely independent function generators, the module features several ways to link these channels together. Use the LINK button (together with the TRIG inputs) to fire off multiple ... -
Page 20: End Of Rise Link
BURST mode triggers an EOR at the beginning of every pulse within the burst. LFO mode triggers an EOR every time the LFO completes half its cycle. For a complete description of exactly when EOR and EOF are triggered for each of Quadrax’s five modes, see Using the Optional Qx ... -
