Yamaha PA Amp

[Gab250]

G'day, I've got a Yamaha PA amp/powered mixer (EMX640)) and it's got a setting that says "PHAMTOM +48V" and you can turn it on or off, what's this likely for? Doesn't seem to make any difference if it's on or off? Also I'm wondering about the best way I can plug, say, a phone into it for tunes, It's got a AUX input, but it seems that it's just for a GUITAR LEAD (mono) and it's got a Tape 1 and Tape 2 input, I'm not expecting stereo sound out of it, but wondering how I can get both channels, without making up a special lead.

Cheers, Gab

Phantom power is for powering microphones that need power... eg: condenser mics.

Most are +48VDC and there are some that operate at lower voltages, but the industry standard is +48VDC.

To connect a phone you will need to use the headphone output of the phone and connect each channel (left and right) to a line level input on the mixer.

The 'Tape' inputs should be OK.

If they have a gain control, you'll need to adjust it and the headphone level on the phone so it doesn't overload/distort the sound.

Phantom power, commonly designated as +48V or P48, was designed to power microphones without using bulky external power supplies such as the ones required for tube microphones. It's a way of sending the DC electrical current required through a balanced XLR cable.

Given the OP has not participated in this (and other threads) he started... saying he only started them as he 'was bored'.
