1. Introduction
The Logitech Z523 2.1 Channel Computer Speaker System is designed to provide a comprehensive audio experience for your computer, gaming console, or other audio devices. Featuring 360-degree sound, this system aims to deliver consistent audio quality throughout your listening space. It includes two satellite speakers for mid-range and high frequencies, and a dedicated subwoofer for deep bass.
This manual provides instructions for setting up, operating, and maintaining your Logitech Z523 speaker system, along with troubleshooting tips and product specifications.
2. Package Contents
Verify that all items are present in your package:
- One (1) Logitech Z523 Subwoofer
- Two (2) Logitech Z523 Satellite Speakers (Left and Right)
- Audio Input Cables (3.5mm and RCA)
- Power Cable

3. Setup Instructions
- Positioning the Speakers:
Place the subwoofer on the floor, ideally near a wall or in a corner for optimal bass response. Position the two satellite speakers on either side of your listening area, such as on a desk next to your computer monitor. Ensure the speakers are facing towards you for the best 360-degree sound experience.
- Connecting the Satellite Speakers:
Connect the left satellite speaker to the subwoofer using the integrated RCA cable. Connect the right satellite speaker to the subwoofer using its integrated multi-pin connector. Ensure these connections are secure.
- Connecting Audio Input:
The Z523 system supports multiple audio inputs. You can connect your audio source (e.g., computer, gaming console, MP3 player) using either the 3.5mm audio jack or the RCA input jacks located on the back of the subwoofer. Use the appropriate cable for your device. The system can automatically switch between inputs if both are connected.
- Power Connection:
Plug the power cable into the subwoofer's power input, then connect the other end to a standard electrical outlet.

4. Operating Instructions
- Powering On/Off:
The power button is integrated with the volume control knob on the right satellite speaker. Rotate the volume knob clockwise until you hear a click to turn the system on. Rotate it counter-clockwise until it clicks to turn the system off.
- Adjusting Volume:
Use the large knob on the right satellite speaker to adjust the overall system volume. Rotate clockwise to increase volume, counter-clockwise to decrease.
- Adjusting Bass:
The smaller knob located below the volume control on the right satellite speaker controls the subwoofer's bass level. Adjust to your preference. Note that excessive bass may lead to distortion at higher volumes.
- Using the Headphone Jack:
A 3.5mm headphone jack is located on the right satellite speaker. Plugging in headphones will mute the speakers, allowing for private listening.
- Using the Auxiliary Input:
An additional 3.5mm auxiliary input jack is available on the right satellite speaker for connecting a secondary audio source, such as a smartphone or tablet. This input can be used simultaneously with the main input on the subwoofer.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the speaker surfaces. Avoid abrasive cleaners or solvents.
- Dust: Regularly dust the speaker grilles and subwoofer to prevent accumulation, which can affect sound quality.
- Environment: Keep the speakers away from direct sunlight, heat sources, and excessive moisture.
- Cables: Ensure all cables are securely connected and not under strain. Avoid bending cables sharply.
