Question 1

Will this work with passive speakers?

Accepted Answer

Yes and I've found it very effective. Just make sure your speakers have a compatible impedance - this amp can handle between 4 and 8 ohm speakers ( I think that's right).

Question 2

Do any of you who own this amp for your turntable ground yours with the screw next to the phono in?

Accepted Answer

You need to use a phono pre-amp to use this Lepy amplifier with a turntable that has no built in pre-amplifier and, therefore, no  Line Out pair of sockets. This is to, both, amplify the cartridge output and to apply RIAA phono equalisation.  Here is a typical unit:

You are quite likely to have excessive hum if you don't use the turntable earth connection. The above preamplifier appears to have a brass terminal to connect the turntable earth. If you get a phono preamplifier without a terminal, connect the turntable earth point to ONE of the phono shield connectors (the part of the phono plug that goes outside of the RCA socket).

If your turntable has a built-in phono preamplifier, you will not need to make this connection. However, such turntables don't usually have an earth terminal.

Question 3

Will this work with a cb radio

Accepted Answer

It will amplify the sound from any kind of radio provided the radio has an AUX output socket and you have a suitable connecting lead.  If the radio has no AUX socket, then you won't be able to connect the LP-2020A. If the CB radio has a headphone socket, you might be able to use that instead, if the sound is not distorted. If the CB radio has no AUX or Headphone socket, you could ask a radio repair shop to fit one.

Question 4

Is this what i need to connect a turntable with red and white rca plugs to speakers?

Accepted Answer

If your turntable has line level out (as opposed to phono level out) then yes... otherwise you will also need a phono pre-amp to boost the signal from the turntable before connecting to the Lepy amplifier. Just check your turntable manual to see if it has an integrated pre-amp and line level out (most old turntables don't).
