Description
Create a powerful single-zone music and paging system for a larger commercial facility with the TEXONIC EX350D mixer amplifier.
The EX350D delivers 350W of efficient Class-D amplification from a slim 1U rack-mount chassis. Built-in Bluetooth, USB playback, microphone mixing and announcement-priority functions make it a practical control centre for distributed commercial speakers.
High-Capacity Commercial Audio
The 350W output gives system designers more flexibility when a business requires additional speakers, wider coverage or higher sound levels.
Compatible ceiling, wall, pendant and paging speakers can be combined on one properly calculated constant-voltage speaker line.
Recommended Applications
- Large retail stores and showrooms
- Restaurants and hospitality facilities
- Schools and educational buildings
- Warehouses and distribution centres
- Gyms and recreation facilities
- Offices and multi-room business spaces
- Community and public facilities
- Commercial music and paging systems
Single-Zone System Operation
The EX350D is a single-zone mixer amplifier. All connected speakers receive the same selected music and paging program.
Compatible commercial volume controls may be installed in selected areas for local volume adjustment. Separate music in different areas requires a matrix or multi-zone amplifier.
Convenient Background Music Playback
Bluetooth provides quick wireless playback from a compatible phone, tablet or computer.
Music may also be played from a compatible USB storage device. The front-panel controls and supplied remote allow staff to manage normal playback without accessing the rear connections.
Three Microphone Inputs for Paging
Three microphone channels support live announcements, staff calls, customer communication and general public-address applications.
- MIC 1 and MIC 2 unbalanced inputs
- MIC 3 balanced input
- Individual microphone level controls
- MIC 1 priority for important announcements
- Built-in pre-announcement chime
- General alarm-tone function
Automatic Priority Control
The priority system helps important announcements and alert tones remain audible over normal background music.
Priority sequence: Alarm → MIC 1 → MIC 2 / MIC 3 → AUX audio
Activating a higher-priority source reduces the lower-priority program so the message can be heard more clearly.
Connect Dedicated Music Sources
Two AUX inputs accept compatible line-level equipment such as a network streamer, computer, television, media player, tuner or audio receiver.
Independent input controls allow the microphone, AUX, Bluetooth and USB signals to be balanced before setting the final master volume.
Line Output for Future Expansion
The line-level output carries the mixed audio program to compatible external equipment. It can feed an additional power amplifier, audio processor or recording device when the system needs to expand.
70V and 100V Distributed Speaker Systems
The constant-voltage outputs are designed for commercial installations using multiple compatible speakers with built-in transformer taps.
Choose either the 70V or 100V system voltage and connect all speakers in parallel using the matching transformer taps. Add together the selected wattage of every connected speaker.
Speaker tap settings may vary according to the required sound level. Lower taps are suitable for quieter rooms, while higher settings may be used in larger or noisier areas.
Speaker Load and 20% Operating Reserve
The total wattage of all connected speaker taps must remain below the EX350D amplifier’s 350W rated output. Maintaining approximately 20% unused capacity is recommended for dependable commercial operation.
Rated amplifier output: 350W
Recommended 20% reserve: 70W
Recommended maximum speaker-tap load: Approximately 280W
Calculate the combined speaker load after every tap adjustment or system expansion. Do not assume that every speaker must use the same wattage setting.
Low-Impedance Speaker Output
The EX350D also supports a properly designed 8–16Ω speaker load. Confirm the total impedance, cable distance and speaker power requirements before selecting low-impedance operation.
Important Speaker Connection Notice
Use only one speaker output type for the entire system: 70V, 100V or 8–16Ω low impedance.
Do not operate different output types at the same time. Confirm the selected output, speaker transformer taps, total load and wiring polarity before turning on the amplifier.
Slim 1U Rack-Mount Chassis
The EX350D occupies only one space in a standard 19-inch equipment rack, helping conserve room for streamers, microphones, processors and other commercial AV equipment.
Keep the ventilation openings clear and provide adequate airflow around the amplifier. Do not place heat-producing equipment directly against the chassis without suitable ventilation.
Protection and Status Indicators
- Short-circuit protection
- Amplifier-overload protection
- Thermal protection
- Power and signal indicators
- Clip and protection indicators
A continuously active clip or protection indicator may point to excessive input level, incorrect speaker loading, a wiring fault or insufficient ventilation.
