Following testing of the initial prototype, new revision of the SamplerBox PCB is getting ready for manufacture. The dimensions were reviewed to reduce size of the board and also to locate audio connectors and controls on the back of the device.

Large balanced TRS jacks have been replaced with minijack to make the SamplerBox more miniature. The circuitry is designed to allow connecting SamplerBox to either unbalanced or balanced inputs using a special balanced cable, which offers same level of noise protection as TRS jacks.
