Dynacord U30:1M-US – 30W Single-Channel Mixer Amplifier

Product Overview

The Dynacord U30:1M is a 30 W mixer amplifier built for small commercial spaces that need background music and clear paging from a single compact unit. As a 70V mixer amplifier, it drives 70 V and 100 V distributed audio lines as well as 4 ohm and 8 ohm low-Z loudspeakers, making it a flexible commercial background music amplifier for cafes, retail floors, and meeting spaces. The integrated four-input mixer, EMG override, and half-rack chassis let integrators deploy a complete paging-and-music head end without a separate mixer.

Product Description

The U30:1M combines a four-input mixer and a Class-D power amplifier in one half-rack 1U enclosure, so a small system can run music sources and microphone announcements from a single device. Two mic/line inputs with switchable 48 V phantom power accept microphones or line sources, while two stereo aux inputs (summed to mono) handle background music players. The EMG priority input accepts both line-level and 100 V signals with selectable level, ensuring emergency and all-call messages override program audio. A call-station interface on MIC1 supports contact-closure triggering with a configurable two-tone chime, and VOX ducking on MIC2 automatically lowers music under live speech for intelligible announcements. The amplifier outputs to 4 ohm, 8 ohm, 70 V, and 100 V loads, selectable by DIP switch, so the same unit fits high-Z distributed ceiling systems or low-Z surface speakers. This Dynacord U Series amplifier suits 24/7 commercial deployment, with remote power standby for energy efficiency and front-panel gain, bass, and treble controls for quick setup. It is part of the Dynacord lineup at Creation Networks; for larger DSP-equipped install systems, compare the Dynacord C1300FDi DSP power amplifier, or browse the full Dynacord collection.

Key Features

• Four-Input Mixer Amplifier — Two mic/line and two aux inputs let one unit blend microphones and background music without an external mixer.
• 70 V / 100 V and Low-Z Output — Selectable 4 ohm, 8 ohm, 70 V, and 100 V operation covers both distributed high-Z and direct low-Z loudspeaker systems.
• EMG Priority Override — A dedicated emergency input accepts line-level or 100 V signals with level selection so critical messages take precedence over program audio.
• Call-Station Interface with Two-Tone Chime — MIC1 supports contact-closure paging with a configurable attention chime for clear all-call announcements.
• VOX Ducking — Automatic ducking lowers background music under live speech for intelligible voice announcements.
• Class-D Topology — Class-D amplification improves energy efficiency and reduces heat compared with traditional linear and Class-AB designs.
• Switchable 48 V Phantom Power — Both mic inputs supply phantom power for condenser microphones and powered call stations.
• Half-Rack 1U Chassis — Included brackets allow single, side-by-side rack, table-top, or under-counter mounting, with two units fitting one rack space.
• Switchable 120 Hz High-Pass Filter — A selectable HPF removes unwanted low-frequency content to protect small speakers and improve speech clarity.
• Remote Power Standby — Contact-closure remote power off reduces standby consumption to 0.6 W for energy-conscious installations.

Frequently Asked Questions

Does the U30:1M support both 70 V and 100 V distributed speaker systems?
Yes. The output stage is DIP-switch selectable for 4 ohm, 8 ohm, 70 V, and 100 V operation, so it works with high-Z distributed ceiling and pendant systems as well as low-Z surface speakers.

Can it page over background music automatically?
Yes. VOX ducking on the MIC2 input automatically lowers music when speech is detected, and the EMG priority input overrides all program audio for emergency or all-call messages.

How does it integrate with a call station?
The MIC1 input includes a call-station interface on a 5-pin Eurostyle connector with contact-closure triggering and a configurable two-tone chime. It is compatible with the Dynacord PLE-1CS all-call station.

How is the amplifier mounted in an equipment rack?
The half-rack 1U chassis ships with brackets for single rack-mount, side-by-side mounting (two units per rack space), table-top, or under-counter installation.

Does it require microphone phantom power?
Both mic/line inputs provide switchable 48 V phantom power for condenser microphones and powered call stations; it can be turned off for dynamic mics.

What warranty and support are available?
Dynacord products carry the manufacturer's standard warranty. Creation Networks provides pre-sale system design guidance and post-sale support for commercial AV deployments. Contact our team through the Creation Networks site for documentation and assistance.

Is this model suitable for 24/7 operation?
Yes. The fanless Class-D design, protection circuitry, and remote standby make it appropriate for continuous fixed-install commercial use in small spaces.
