INTRODUCTION

For many years, VOX has been designing and manufacturing some of the most renowned
amplifiers in the world and today is no exception. We’re honoured that you have chosen
to add the AC Hand Wired series to your sonic arsenal!

Beautifully hand built, using the finest components and custom parts to bring together the
old and the new.

This is classic VOX with a modern twist.

Not satisfied with just dusting off old designs, we have taken the iconic TOP BOOST
channel from our AC30 and given it a modern shake up…

The TOP BOOST channel has GAIN, TREBLE and BASS controls, but we’ve added
something extra HOT!

The Top Boost channel now features two distinct modes, “COOL” and “HOT”. COOL is
classic VOX; shimmering highs and gorgeous breakup. HOT is something a little different.
When in HOT mode, the TOP BOOST tone controls are bypassed for a more pure signal
path and what this means to you is more gain... a lot more GAIN!

Best of all, the HOT mode can be engaged with the supplied VFS1 Foot Switch making it
ideal for a lead boost when you need to nail that killer solo!

Owner’s Manual

Finally, the single ended class A power stage can be controlled using the VOLUME con­trol which allows you to get the saturated tones the amp does so well without waking the
neighbours!

We believe this to be one of the most sonically versatile Hand Wired VOX amplifiers to
date, and is well on the way to joining its Grandfathers in the VOX hall of fame.

Enjoy!

1. INPUT HIGH/LOW

Insert your guitar into either one of these inputs. The LOW input will
give you more clean headroom and the HIGH will give you more gain.

2. GAIN control This controls the preamp volume and will determine the amount of

preamp distortion. For a clean sound, the knob should be set some­where before 12 o’clock and for more distortion… crank it!

3. TREBLE control This controls the high frequencies in your sound—from soft and

smooth when turned down (counter clockwise) to bright and cutting
when cranked (clockwise) and all points in-between.

4. BASS control This controls the low frequencies in your sound—from thin and light

when turned down (counter clockwise) to warm and fat when turned
up full (clockwise) and all points in-between.

5. HOT/COOL Switch

When set to COOL mode the Top Boost channel operates in tradi­tional fashion with the TREBLE and BASS controls activated and
when set to HOT mode, the tone controls are bypassed providing a
substantial gain boost. HOT mode must be engaged for the footswitch
to work.

NOTE: When in HOT mode the tone controls still affect the sound slightly.

6. VOLUME control This controls the overall volume of your amplifier and because this is

a single ended, class A design it will also have an effect on the amount
of distortion in the power amp.

7. POWER Switch This turns the amp on and off! Please ensure the amplifier is switched

off and unplugged before being moved.

8. Indicator This will tell you if your amp is on or off!

1. FOOT SWITCH Jack

This is where you connect the included Foot Switch (VFS1) to switch
between HOT and COOL modes on the TOP BOOST Channel (HOT
mode must be engaged on the control panel for the Foot Switch to
operate).

2. EXTERNAL SPEAKER OUT

This is used to connect the AC4HW1 to any 16ohm cabinet.

NOTE: When an external cabinet is connected, the internal speaker is dis-

connected.

WARNING: To ensure that your system works correctly, you must observe the

following points.

Owner’s Manual

a) Don’t use an external cabinet whose impedance is other than 16

ohms.

b) Don’t connect a speaker whose rated input capacity is less than 4

Watts. The speaker may be destroyed if you ignore this caution—not
recommended!

c) You must use a speaker cable to connect an external speaker. Don’t

use a shielded cable like the one you use to connect a guitar to an
amp.

d) You must turn off the power before connecting the cable. Connecting

the cable while the power is turned on may damage your amp.

3. MAINS INPUT Connect your supplied mains power lead here

NOTE: Use only the power cable that is included with the AC4HW1. Using

another power cable may cause malfunctions.

The specific mains input voltage rating that your amplifier needs to run
at is located on the rear panel of your amplifier. Before making any
connections or powering up the amplifier, make sure the correct volt­age is set. If you have any doubt, refer to your local VOX dealer.
