From a single microphone, amplifier, or pair of speakers to a complete home karaoke or commercial audio system, we help customers nationwide choose equipment that fits their needs and budget.

Why Choose ACI Audio / ACICO?

Professional System Design

A good audio system is more than a collection of expensive products.

Speakers, amplifiers, microphones, processors, karaoke machines, subwoofers, and other components must work together correctly.

Our team considers factors such as:

• Room size
• Speaker type
• Amplifier power
• System impedance
• Number of channels
• Application
• Installation environment
• Customer budget

We carefully match equipment to create systems with the right balance of clarity, power, reliability, and ease of use.

Complete, Ready-to-Use Packages

For customers who prefer a complete solution, we offer professionally matched system packages.

Depending on the system, a package may include:

• Speakers
• Amplifier
• Karaoke processor
• Wireless microphones
• Karaoke machine
• Power management
• Cables
• Connectors
• Accessories

This reduces compatibility problems and makes installation and setup much easier.

Premium International Brands + AC Professional Audio

ACI Audio / ACICO carries products from established professional audio manufacturers as well as our own AC professional audio line.

Brands available through our store may include:

• JBL
• Martin Audio
• Shure
• BMB
• Crown
• QSC
• Yamaha
• RCF
• AC Professional Audio

By offering both internationally recognized brands and AC products, we can provide solutions for different system requirements and budgets without sacrificing professional performance.

Home Karaoke Expertise

Home karaoke is one of our core specialties.

A properly designed home karaoke system should provide clear vocals, balanced music, strong dynamics, and comfortable sound for long listening sessions.

We help customers select and match:

• Karaoke speakers
• Mixing amplifiers
• Power amplifiers
• Sound processors
• Wireless microphones
• Karaoke machines
• Subwoofers
• Accessories

For Southern California customers, we can also provide installation and professional on-site tuning.

For customers elsewhere in the United States, we provide remote assistance for equipment selection and system setup.

Commercial Audio & KTV Solutions

We also provide professional audio solutions for commercial environments including:

• Restaurants
• Bars
• KTV venues
• Clubs
• Churches
• Conference rooms
• Meeting spaces
• Event halls
• Entertainment venues
• Commercial facilities

Commercial systems often require different considerations than home audio systems, including coverage, system reliability, power requirements, equipment protection, microphone performance, and long operating hours.

We can assist with both equipment selection and complete system planning.

Professional Installation & Tuning

Professional equipment does not automatically guarantee professional sound.

Installation, signal routing, gain structure, speaker placement, crossover settings, EQ, microphone processing, amplifier configuration, and system tuning can all make a major difference.

For customers in Southern California, our team provides professional installation and system tuning to help equipment perform as intended.

Our goal is not simply to make the system produce sound.

Our goal is to make the entire system work properly together.

Remote Technical Support

For customers outside our local service area, we provide remote technical support when possible.

Our team can assist with:

• Equipment connection
• Signal routing
• System configuration
• Karaoke setup
• Basic tuning guidance
• Troubleshooting
• Product compatibility
• Future system upgrades

This gives customers nationwide access to professional support even when an on-site visit is not available.

Warranty & After-Sales Support

Our relationship with customers does not end when an order is delivered.

AC-branded products include a one-year in-house warranty for parts and labor, while products from other manufacturers may include their respective manufacturer warranties.

We also continue to assist customers with system setup, troubleshooting, technical questions, and future upgrades.

Long-term technical support is an important part of how we operate.
