Controls
- CV IN – Each channel has its own CV input which is cascaded to the channels below, provided that they do not have a CV cable inserted. If only CV IN 1 is connected it will control all 4 channels. Each CV input has an associated CV LED which lights green for a positive CV (VCA gain) and red for a negative CV (VCA attenuation), if the CV IN voltage is 0V then the LED does not light.
- CV ATTENUATOR – Each channel has a CV Attenuator, which can reduce the CV input signal level when moved CCW.
- BOOST – Each channel has a switchable Boost control, which raises the input gain by +6 dB when the switch is set in the right-hand position.
- CURVE – Each channel has a continuously variable VCA response curve, ranging from exponential at full CCW to linear at full CW.
- LEVEL – Each channel has its own overall VCA output level control. The response of the Level control is affected by the Curve control setting.
- INPUTS – Each channel has its own input, which can be used with audio or CV input signals.
- OUTPUTS – Each channel has its own output, which is mixed with channels to the right if no output cable is inserted into that channel output. If only the 4/Mix output jack is connected the module operates as a 4 into 1 mixer, which can be operated manually using the Level controls, or voltage controlled via the CV inputs.
Power Connection
The Four Play module comes with the required power cable for connecting to a standard Eurorack power supply system. Follow these steps to connect power tothe module. It is easier to make these connections before the module has been mounted into a rack case.
- Turn the power supply or rack case power off and disconnect the power cable.
- Insert the 16-pin connector on the power cable into the socket on the power supply or rack case. The connector has a tab that will align with the gap in the socket, so it cannot be inserted incorrectly. If the power supply does not have a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
- Insert the 10-pin connector into the socket on the back of the module. The connector has a tab that will align with the socket for correct orientation.
- After both ends of the power cable have been securely attached, you may mount the module in a case and turn on the power supply
Installation
The necessary screws are included with the module for mounting in a Eurorack case. Connect the power cable before mounting. Depending on the rack case, there may be a series of fixed holes spaced 2 HP apart along the length of the case, or a track that allows individual threaded plates to slide along the length of the case. The free-moving threaded plates allow precise positioning of the module, but each plate should be positioned in the approximate relation to the mounting holes in your module before attaching the screws. Hold the module against the Eurorack rails so that each of the mounting holes are aligned with a threaded rail or threaded plate. Attach the screws part way to start, which will allow small adjustments to the positioning while you get them all aligned. After the final position has been established, tighten the screws down.
