Product information

Description

The AUDAC SMQ500 audio amplifier 4.0 channels Black Class D is a quad-channel Class D power amplifier designed for professional fixed and mobile audio installations. It combines compact dimensions with a set of DSP-driven tuning tools and robust protection mechanisms to deliver reliable, low-distortion amplification. The amplifier offers four output channels, low total harmonic distortion (0.05%) and flexible input/output connectivity suitable for a wide range of sound reinforcement, commercial and installed-audio applications.

Advantages

The unit provides high audio fidelity with minimal harmonic distortion and configurable output power limiting per channel for loudspeaker protection. Integrated WaveDynamics™ DSP with a 2.5” LCD display enables on-unit configuration of crossover filters (Butterworth, Bessel, Linkwitz-Riley), selectable rolloff, a 7-band equalizer with adjustable Q, delay and dynamic bass boost. Multiple input types and a selection matrix increase source compatibility, while thermal, overload and short-circuit protection ensure operational safety in demanding environments.

Suitable for (tasks / use cases)

  • Small to medium venue sound reinforcement
  • Fixed commercial audio installations (retail, hospitality, corporate)
  • Portable or mobile PA systems and rental setups
  • Multi-zone or distributed audio systems requiring quad-channel amplification

Key specifications

  • Amplifier class: Class D
  • Channels: 4.0 (four independent output channels)
  • Total harmonic distortion (THD): 0.05%
  • DSP processor: WaveDynamics™ with 2.5” LCD display
  • Filters: Butterworth, Bessel, Linkwitz-Riley with selectable rolloff; Low/High/Band Pass
  • Equalizer: 7-band graphic EQ with adjustable frequencies and Q-factor
  • Protection: thermal, overload and short-circuit protection; configurable per-channel power limiter
  • Input connections: XLR and terminal block, input selection matrix
  • Output connections: speaker terminals and terminal block
  • Control/interface: RS-232 port; optional Dante™ network audio interface available
  • Weight: 8.25 kg
  • Colour: Black

How to use

Install the amplifier in a suitable rack or stable surface, ensuring adequate ventilation to avoid overheating. Connect source devices to the chosen inputs (XLR or terminal block) and route speaker outputs to the appropriate channels using speaker terminals or the terminal block. Use the front-panel WaveDynamics™ interface and 2.5” LCD to select input routing, apply crossover and equalization settings, set delay and dynamic bass boost, and configure per-channel power limits. For multi-unit setups or remote control integrate via the RS-232 port, or add the optional Dante™ interface for networked audio distribution. Always verify speaker impedance compatibility and start with conservative gain settings before increasing level.

Usage recommendations

Allow sufficient airflow around the amplifier, avoid stacking heat-generating equipment directly above it, and use the built-in protection and power limiter settings to protect loudspeakers. Save preferred loudspeaker presets and system configurations to a USB flash drive for quick deployment and reproducible setups.

Amplifier class: An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. Power amplifier circuits (output stages) are classified as A, B, A/B and C for analog designs, and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device is passing current.

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
