Can You Connect a Turntable to the Fosi BT20A Pro?
See all Fosi BT20A Pro compatibility questions
Short answer: yes, but the BT20A Pro’s RCA input is a line-level input, not a phono input. A turntable needs a phono preamp before the amplifier unless the turntable already has a built-in phono preamp.
Turntable with a built-in phono preamp
Set the turntable to its line-level output mode, then connect its RCA output to the BT20A Pro RCA input.
Turntable without a built-in phono preamp
The chain is turntable → phono preamp → BT20A Pro RCA input → passive speakers. The phono preamp both raises the very low cartridge signal to line level and applies the required phono equalization.
What will not work well
Connecting a typical phono-level turntable directly to the BT20A Pro RCA input will usually produce a very quiet, thin signal because the amp is expecting line level.
