Frequently Asked Questions - AC PRO 60 Harley Benton

How do I connect my guitar to the amplifier?

Use a standard 1/4" instrument cable to connect your guitar to the Input jack located on the front panel. Ensure the amplifier is powered off or volume turned down before connecting.

What is the power output of the AC PRO 60?

The amplifier delivers 60 Watts RMS through its built-in 12" speaker, suitable for practice and small gigs.

How can I use headphones with this amplifier?

Plug your headphones into the Headphone Jack on the front panel. This will mute the internal speaker, allowing silent practice.

Does the amplifier have a line output?

Yes, it features a Line Out (1/4" jack) for connecting to a mixing console, recording interface, or external power amp.

How do I switch between clean and overdrive channels?

Use the Channel Switch button on the front panel (or an optional footswitch) to toggle between Clean and Overdrive channels. Adjust the Gain control for desired distortion.

Can I connect an effects pedal?

Yes, you can connect pedals in front of the amplifier (guitar -> pedal -> amp input) or use the Effects Loop (Send/Return) for time-based effects like delay and reverb.

What type of reverb does the amplifier have?

It features a built-in spring reverb controlled by the Reverb knob. This adds natural ambience to your sound.

How do I clean and maintain the amplifier?

Unplug the amplifier and wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Keep the ventilation slots free from dust.

What should I do if the amplifier doesn't power on?

Check that the power cord is securely connected to both the amplifier and a working wall outlet. Verify the power switch is on. If it still doesn't power on, contact a qualified technician.

Is a footswitch included?

No, the footswitch is optional. You can use a standard two-button footswitch (tip: channel, ring: reverb) to remotely control channel switching and reverb.

CAUTION!

Possible hearing damage

The device can produce volume levels that may cause temporary or permanent hearing impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage.

Decrease the volume level immediately if you experience ringing in your ears or hearing impairment. If this is not possible, keep a greater distance or use sufficient ear protectors.

NOTICE!

Risk of fire

Do not cover the device nor any ventilation slots. Do not place the device near any direct heat source. Keep the device away from naked flames.

NOTICE!

Operating conditions

This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations.

NOTICE!

Power supply

Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do so could result in damage to the device and possibly injure the user.

Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire.

7 Plug and connection assignment

Introduction

This chapter will help you select the right cables and plugs to connect your valuable equipment in such a way that a perfect sound experience is ensured.

Please note these advices, because especially in 'Sound & Light' caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or 'just' in poor transmission quality!

Balanced and unbalanced transmission

Unbalanced transmission is mainly used in semi-professional environment and in hifi use. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is transmitted through the core.

Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables.

In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conductors 'Ground' and 'Signal', in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180^ .

AC PRO 60

Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise interference.
