Also The Metal mod is really loud that i can't even try it.I live in apartment so its too loud for me.Its not like the clean sound's loudness.There is too big differences.Any options to plug a headphone ? I didn't get one with my Spider IV 15

I bought A Line 6 Spider IV 15 W today.Tried it with my guitar "Ibanez grg140" on clean tone.When i switched it on it made a echo sound and later i tried to play some songs but there was a echo sound at the background.How do i turn it off ?.I'm new to electric guitar so i don't know this things very well.Thanks.
