B. The Rear Panel

1. AC POWER CONNECTOR

Yes, you’ve guessed it; this is where you connect the included power cord.

2. EXTERNAL SPEAKER OUT Jack(s)

This is where you can hook up external speaker cabinet(s) if you’d like to. The

AD60VT has one (1) EXTERNAL SPEAKER OUT jack, while the AD120VT has

two (2). Why does it have two? Because the AD120VT is a stereo amp!

IMPORTANT NOTE: The internal speaker(s) in your Valvetronix combo remain con-

nected when external speakers are connected. For optimum performance we

strongly advise the following:

1. Only use extension speaker cabinets of 8 Ohms impedance or less (e.g. 4

Ohms) with these combos. And, if you’re using a stereo cabinet with the

AD120VT make sure each side (Left & Right) has an impedance of 8

Ohms or less.

ANOTHER IMPORTANT NOTE: The VOX AD-212 2x12 stereo extension cab-

inet is available and matches the AD120VT perfectly in both looks and sound.

2. Do NOT use a speaker cabinet with a Wattage rating that is less than 60

Watts, or less than the output power you’ve selected with the POWER

SELECT Control (5). If you ignore this warning, you could end up blowing

a speaker - and that’s not recommended!

3. ALWAYS use speaker cables (unshielded) to connect external speakers -

NEVER use a guitar (shielded) cable.

WARNING: If a cabinet with an impedance higher than 8 Ohms - like a 16

Ohm one for instance - is used in conjunction with your Valvetronix amp, the

amp will suffer from an audible drop in output power, due to the nature of the

external speaker jack circuit.

3. POWER SELECT Control

This incredibly cool feature enables you to choose from four (4) different output

Wattages. The selections are:

AD60VT: 60 Watts (W), 30W, 15W and 1W.

AD120VT: 60W + 60W (60 Watts per side), 30W + 30W, 15W + 15W, 1W +

1W.

This means you can get that highly desirable, fat, warm sound of the Valvetronix

power stage being driven hard (a common trait of all great valve power amps), at

various levels - very loud, not quite so loud, reasonable and relatively quiet! This
