When I first received my FUN unit, the volume knob was getting hung up in a range between about 7 o'clock to 10 o'clock. I just pulled out on the knob a little and that freed it up so it rotates smoothly throughout the entire range.
Advice on installation, customization, and anything else.
The FUN functions:
Gain button: Push in for low gain (+2DB), out is high gain ( +13DB).
Volume knob: Control the volume level of the headphone/pre amp.
Line Out: Push in for headphone output, out for preamp output.
Line In: Push in for analogue input, to use it as just a headphone amp or preamp, leave out to use with the in-built DAC.
Selector knob: Select built in DAC source between USB , coaxial and optical.
Power socket: For power input.
USB socket: For USB input.
Opt socket: For optical input.
Coa socket: For coaxial input.
DAC out sockets: For in-built DAC analogue output.
Line In sockets: For extra analogue input, to use FUN as just a headphone amp or preamp, leave out to use with the in-built DAC.
Line out sockets: Out for preamp output.
Advice for using FUN as a dedicated DAC:
The FUN has special DAC output sockets, owners can connect to the DAC output sockets, but I advise owners to try to connect to the Preamp output sockets, turn the volume to proper position (at high gain, volume placed around 10:00 to 14:00) which is proper output level. Doing this benefits from the ACSS gain circuits , and can improve the sound quality. Owners can compare between these two outputs, see which one sounds better.
Don't worry that the multiple output stages will degrade sound quality, most DACs or CDPs also have multiple output stages but some of them sound excellent.
