Audac SMQ750 Quad Channel Power Amplifier – Doneo Malta
WaveDynamics Quad Channel Power Amplifier 4 X 750W
The SMA & SMQ amplifiers are defining a new standard in affordable amplification for both fixed and mobile audio installations. Their different channel configurations and availability in various output powers are providing an enormous flexibility for numerous applications.
The SMQ750 is the four channel version of this Class D power amplifier with an output power of 750 Watt for each channel. The WaveDynamics™ DSP processor in combination with the 2.5” LCD display gives an unmatched user experience with intuitive functions overview for easy configuration.
Acoustics can be optimized using the filters selectable between Low / High & Band Pass and the 7-Band equalizer which both have adjustable frequencies and Q-factor. Other provided functions are delay and dynamic bass boost. These settings can be custom configured using the front panel of the amplifier, whereby access can be given in two different levels (User & Administrator) using password or USB-key protection. Loudspeaker protection is provided by an output power limiter whereby the maximum output power for every channel (in Watt) can be configured.
Configuration is made simple by the loudspeaker presets and full system configurations which can selected from a library and uploaded with an USB flash drive. This ensures the best acoustical performance with a bullet-proof loudspeaker protection.
A great input flexibility and source compatibility is provided by the input selection matrix in combination with the XLR and terminal block signal connections. The outputs are performed using Speaker and Terminal block connections. System integration is made easy using the RS-232 control port.
- Lightweight Class D amplifier
- Advanced DSP & loudspeaker management
- Intuitive graphical interface on 2.5” LCD display
- Pre-loadable loudspeaker & set configurations
- Unmatched technology and affordability
- Flexible input and output configuration
- XLR & terminal block source compatibility
- RS-232 control and USB loadable configurations
A complete library of AUDAC loudspeaker and set solution presets is available for your projects, making it easy as picking the right file, loading it & play! Besides the optimal acoustic configurations, this library also includes the loudspeaker performance parameters providing a bulletproof protection for them.
The 7-Band fully parametric equalizer with adjustable frequency and Q factor and Butterworth, Bessel and Linkwitz-Riley filters with selectable roloff allow you to create custom configurations, tweak your setup to the finest detail and adapt to your room’s acoustics. A delay function allows time-alignment of different speakers in your installation.
Configurations also allow you too bridge the outputs, double the output power of stereo channels to one mono channel or make a single three-channel amplifier driving a complete setup composed of stereo Mid/High frequency speakers and a bass cabinet.
The operation and configuration of the device can be done in multiple ways. The most obvious way is by using the front panel controls, featuring a rotary selection dial and channel selection buttons with a clear and intuitive user inferface on the 2.5″ graphical LCD Display.
Total system configurations for pre-defined set solutions can be loaded into the amplifier using the USB port.
Integration of the audio system into home and industrial automation systems is made easy through the RS-232 connection & control port whereby functions such as input switching, volume adjustment, … can be controlled.
Every system comes with different requirements and every customer has his own preferences. Because of this, the structure is made as flexible as possible.
This is achieved by an input selection matrix. Each of the input connections can be patched to any amplifier channel and contains software controllable gain. The different implementations of the in- and output connectors allow the easiest way of connection for every application, while allowing signal link through to other amplifiers
Optimal protection is not only required for the listeners satisfaction, but can also be important for complying to the imposed regulations and guaranteeing the lifetime of the equipment. Because of this, protection precautions are implemented in different ways.
Firstly, user access is made possible on different levels. The device can be blocked or accessed in user or administrator level. Different levels allow different configuration and control functions, giving limited (Eg: only volume) control access to standard users and full configuration control to administrators. User restriction can be enabled & disabled and is given through password and / or USB-key.
Secondly, equipment protection is implemented by an output limiter which monitors the output power of every channel and will intervene when the output exceeds a certain level. The corresponding level can be software configured and is indicated in Watts. When the output limiter is configured at the maximum power of the loudspeaker, you can rest assured that the speakers won’t be blown during your absence.
Lastly, the maximum volume for every channel can be set indepentently. This prevents users (having volume access) going over the limit. This can help you to keep the system compliant with imposed regulations and maintain the good relationship with the neighbors.
The switching mode power supply and Class-D Amplifier technology in combination with the auto-standby mode for each separate amplifier channel brings an end to the era of the power-hungry amplifiers. In addition, these features also result in a lightweight amplifier which benefits the customer when used in mobile applications.
