In the 60s, the first synth modules hit the market and were outrageously pricey. The FOUR PLAY is a contemporary, compact, and super - flexible module. It offers four independent VCA’s and can double as a 4 - channel voltage - controlled mixer, giving you endless possibilities. Modular synths were a game - changer in electronic music, and with the FOUR PLAY, it's only getting better. Features include an ultra - low noise quad VCA and mixer module. Each VCA has a manual Level control for independent mixing. There are dedicated CV attenuators with dual LED's to monitor bipolar CV signals. You can adjust the VCA response curve from linear to exponential. Each CV input and output are normalled for cascaded control. There's also a Boost switch on each VCA for a 6 dB increase in output level. With 16 controls and switches, you have real - time access to all key parameters. It follows Eurorack specs: 12 HP, 100 mA +12V, 100 mA -12V.


Using the Behringer FOUR PLAY is a breeze. First, connect your audio sources to the appropriate inputs. You can use it as four separate voltage - controlled amplifiers or as a 4 - channel mixer. Adjust the manual Level controls on each VCA to mix your sounds independently. Use the dedicated CV attenuators to fine - tune the control voltage signals, and watch the dual LED's to monitor them. You can change the VCA response curve according to your needs, from a linear to an exponential curve. When you want a bit more volume, flip the Boost switch on each VCA. Remember to follow the Eurorack power specs (12 HP, 100 mA +12V, 100 mA -12V) when powering it. For maintenance, keep it in a clean and dry place. Avoid exposing it to extreme temperatures or humidity. If you notice any issues, check the connections first. If the problem persists, contact customer support.
