AUDAC CAP248 Dual-Channel 100V Power Amplifier 2 × 480W – Professional Multi-Zone Audio Amplifier

Product Introduction

The AUDAC CAP248 is a professional dual-channel 100V Class-D power amplifier delivering 2 × 480W continuous output power, designed for commercial audio, public address (PA), background music (BGM), and multi-zone sound systems.

With two independent 480W amplifier channels, the CAP248 is an excellent solution for installations requiring powerful and reliable audio distribution across two separate zones. Its efficient Class-D amplifier technology, switching-mode power supply, advanced protection circuitry, balanced XLR connections, and straightforward controls make it particularly suitable for professional fixed installations.

The CAP248 is ideal for restaurants, hotels, schools, universities, corporate buildings, retail outlets, clubs, houses of worship, function spaces, and other commercial 100V audio systems.

Product Description

Part of the professional AUDAC CAP series, the CAP248 100V power amplifier combines high output capacity, efficiency, reliability, and simple installation in a compact 2U 19-inch rack-mount enclosure.

Each of its two channels provides 480W continuous power at 100V, allowing installers to create two independent loudspeaker zones from a single amplifier. This makes the CAP248 particularly useful for multi-zone commercial audio systems where different areas require dedicated amplification.

The amplifier uses highly efficient Class-D technology combined with a switching-mode power supply, helping reduce weight and power consumption while providing dependable performance for professional applications.

For system integration, each channel features a balanced female XLR input with male XLR link-through, allowing the audio signal to be easily distributed to additional amplifiers. Individual gain adjustment is provided for each channel for accurate system configuration.

A selectable 400Hz high-pass filter (HPF) is also provided per channel. This is particularly useful when the connected loudspeaker system does not require low-frequency reproduction, helping optimize the system for applications such as speech and paging.

Reliability is supported by an integrated multipurpose protection system providing protection against DC malfunction, short circuits, overheating and overload, together with signal limiting when required. A temperature-controlled cooling fan maintains appropriate operating temperatures while minimizing unnecessary fan noise.

Output connections use reliable 4-pin Euro terminal blocks, making the CAP248 suitable for permanent professional AV and commercial audio installations.

Solutions & Applications

Multi-Zone 100V Audio System

The AUDAC CAP248 provides two independent 480W amplifier channels, making it an effective solution for buildings requiring two separately amplified audio zones. Each channel can serve its own group of 100V loudspeakers, simplifying system design while providing substantial output capacity.

Restaurant & Café Background Music

Use one channel for the main dining area and another for a private dining room, outdoor area, bar, or secondary zone. The 100V architecture makes it practical to connect multiple ceiling or surface-mount speakers throughout larger venues.

Hotel & Hospitality Audio

The CAP248 can power distributed loudspeaker systems in hotel lobbies, restaurants, corridors, function areas, lounges and common spaces. Its rack-mount design makes it suitable for centralized AV equipment rooms.

Education & Campus Audio

Suitable for schools, universities, colleges, training centres and lecture facilities, the CAP248 can provide amplification for paging, announcements, speech reinforcement and background audio across two independent areas.

Corporate & Office Audio

Deploy the CAP248 for office background music, corporate communication, training facilities, multipurpose rooms, reception areas and common spaces where reliable 100V distributed audio is required.

Retail & Shopping Environments

The 2 × 480W output capacity makes the amplifier suitable for retail shops, supermarkets, showrooms and commercial spaces requiring multiple loudspeakers for background music and announcements.

Bars & Entertainment Venues

For bars, lounges and clubs using 100V distributed audio, the CAP248 provides substantial power for multiple loudspeakers while maintaining straightforward installation and operation.

House of Worship

The CAP248 can also be integrated into church, mosque, surau and other house-of-worship audio systems, particularly for distributed loudspeaker zones requiring reliable 100V amplification.

Why Choose the AUDAC CAP248?

The AUDAC CAP248 2 × 480W 100V power amplifier is designed for professional installations where reliability, simplicity and high output power are important. Instead of unnecessary complexity, it focuses on the essential features installers need: powerful dual-channel amplification, professional XLR connectivity, individual gain controls, selectable high-pass filtering, advanced protection and reliable terminal-block outputs.

For commercial audio, PA, BGM and multi-zone 100V speaker systems, the CAP248 provides a practical combination of power, efficiency, flexibility and professional-grade reliability.
