This document describes the Harley Benton G112 Guitar Cabinet, a passive guitar cabinet designed for sound reinforcement.
Function Description
The Harley Benton G112 is a guitar cabinet intended for use in sound reinforcement systems. It provides a single 1/4" phone socket for signal input, allowing connection to an amplifier. The cabinet is designed to deliver sound from a guitar amplifier to an audience. It features a half-open MDF housing with a carrying handle for portability.
Important Technical Specifications

The frequency response graph shows the cabinet's output across the frequency spectrum, indicating its performance characteristics. The dBSPL (decibels Sound Pressure Level) is plotted against frequency (Hz and kHz), illustrating the cabinet's sound reproduction capabilities. The response shows a relatively flat range between approximately 200 Hz and 1 kHz, with peaks and dips outside this range, and a significant drop-off below 80 Hz and above 6 kHz, consistent with its specified frequency range.
Usage Features
The G112 is designed for straightforward operation. It has a single 1/4" phone socket for connecting to an amplifier. The pin assignment for the 1/4" jack plug (mono) is standard: pin 1 for signal and pin 2 for ground.
Tips on handling speakers:
- Position speakers to ensure sound signals reach the audience unobstructed.
- Always use high-grade cables for connections to achieve maximum sound quality.
- Ensure that both the impedance and power rating of the speaker match the requirements of the amplifier/input signal. Adhere to the technical specifications of all connected equipment.
- The overall impedance of connected loudspeakers must not exceed the minimum output impedance of the amplifier.
- The amplifier's maximum RMS output power should ideally be 50% above the power handling capacity of the connected speakers.
- If distortion is noticed during operation, it indicates that either the amplifier or the speaker is overloaded. This can cause permanent damage. Immediately reduce the volume level if distortion occurs.
Safety instructions for use:
- The device is intended for sound reinforcement and should only be used as described in the manual. Improper use may lead to personal injury or property damage.
- Only persons with sufficient physical, sensorial, and intellectual abilities, and corresponding knowledge and experience, should operate the device. Others must be supervised or instructed by a responsible person.
- Danger for children: Keep plastic bags and packaging out of reach of babies and young children to prevent choking hazards. Ensure children do not detach small parts. Never leave children unattended with electrical devices.
- Possible hearing damage: The device can produce high volume levels that may cause temporary or permanent hearing impairment. Reduce volume immediately if ringing in the ears or hearing impairment is experienced. If not possible, maintain distance or use ear protectors.
- Operating conditions: This device is for indoor use only. Avoid exposure to liquids, moisture, direct sunlight, heavy dirt, and strong vibrations. Operate within the specified ambient conditions (0 °C to 40 °C, 20% to 80% non-condensing relative humidity). Avoid heavy temperature fluctuations and do not switch on immediately after exposure to low temperatures. Dust and dirt inside can cause damage. Regular maintenance by qualified service personnel is recommended if operated in harmful ambient conditions (dust, smoke, nicotine, fog) to prevent overheating and malfunction.
- Possible staining: The plasticizer in the rubber feet may react with surface coatings, potentially causing permanent dark stains. If in doubt, use a suitable underlay (e.g., felt pads).
- Possible property damage by magnetic fields: Loudspeakers produce a static magnetic field. Maintain an appropriate distance from devices that can be adversely affected or damaged by external magnetic fields.
Maintenance Features
- The product is subject to continuous development, and the manufacturer reserves the right to make changes without notice.
- In case of operation in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by qualified service personnel at regular intervals to prevent overheating and other malfunctions.
Disposal:
- Packaging material: Environmentally friendly materials are used for transport and protective packaging. These materials can be supplied for normal recycling. Dispose of plastic bags and packaging properly, ensuring they are not mixed with normal household waste but collected for recycling according to local notes and markings.
- Old device: This product falls under the European Waste Electrical and Electronic Equipment Directive (WEEE). Do not dispose of it with normal household waste. Dispose of the device through an approved waste disposal firm or local waste facility, complying with country-specific rules and regulations. Consult local waste disposal facilities if in doubt.
