Introduction WELCOME ABOARD AGAIN! M any thanks for adding a VOX Valvetronix head to your sonic arsenal. We’re sure it’ll give you countless hours of great guitar tones that will feel as good as they sound! You may have noticed that this is an addendum to the Combo Manual. This addendum will cover speaker connections and impedance settings for your AD60VTH or AD120VTH head.
AD60VTH SPEAKER CONNECTION CHART AD60VTH If you use: AD212/AD412 mono Set Output Impedance Select to: 16 Ohms Use Speaker Jack: Either one AD212 or AD412 One 16 Ohm cabinet One 8 Ohm cabinet One 4 Ohm cabinet Two 16 Ohm cabinets Two 8 Ohm cabinets Two 4 Ohm cabinets 16 Ohms Either one 8 Ohms Either one 4 Ohms Either one 8 Ohms Both 4 Ohms Both DO NOT DO THIS.

AD120VTH SPEAKER CONNECTION CHART AD120VTH If you use: Set Output Impedance Select to: **AD212/AD412 Stereo 8 Ohms Use Speaker Jack: One from L & R ch. AD212 or AD412 One 16 Ohm cabinet One 8 Ohm cabinet One 4 Ohm cabinet Two 16 Ohm cabinets Two 8 Ohm cabinets Two 4 Ohm cabinets Four 16 Ohm cabinets Four 8 Ohm cabinets Four 4 Ohm cabinets 16 Ohms One from L or R ch* 8 Ohms One from L or R ch* 4 Ohms One from L or R ch* 16 Ohms One from L & R ch. 8 Ohms One from L & R ch. 4 Ohms One from L & R ch.
Input Input Two 8 Ohm cabinets Input Input Input Input Four 8 Ohm cabinets *Because the AD120VTH is a stereo head running at 60 Watts per side, when you hook up a single cabinet to one side, you will only get 60 Watts in mono. You will not get the full effect of running this head at 120 Watts in stereo. We recommend stereo!!!! **This option is highly recommended! This will make you a rock star. OK, maybe not a rock star but you will sound great. If you don’t have this cabinet…you need it.
NERDY IMPEDANCE INFORMATION AHEAD T he following is some information that you’ll find useful for hooking up your Valvetronix AD60VTH or AD120VTH head. When you’re done with this, you’ll be a smarter and better person! Plus you’ll know the correct way for hooking up speaker cabinets in series or parallel. In multiple speaker cabinet configurations, you will have to use a little mathematics (Ohm’s law) in order to figure out the correct setting.
