Audac SMQ350 Wave Dynamics Quad Channel Power Amplifier

Audac SMQ350 Wave Dynamics Quad Channel Power Amplifier in Bangladesh

The Audac SMQ350 is a black, four-channel Class-D power amplifier described as a WaveDynamics model. Its supplied specifications list output ratings of 4 × 350 W at 4 Ω in stereo mode, 4 × 220 W at 8 Ω in stereo mode, and 2 × 700 W at 8 Ω in bridged mode. It is designed for rack mounting in a 19-inch format and has a listed height of 2 HE. These details make it a model to assess for installations that need several amplifier channels in a rack-based system.

The amplifier’s output figures are specified for different load and operating configurations. They are not interchangeable ratings: the 4 Ω stereo, 8 Ω stereo and 8 Ω bridged figures apply to different setups. Check the speaker impedance, wiring plan and amplifier configuration before connecting equipment. Do not select an operating mode based only on the largest wattage figure; follow the amplifier and speaker documentation for the intended arrangement.

The supplied stereo ratings are 4 × 350 W at 4 Ω and 4 × 220 W at 8 Ω. The bridged rating is 2 × 700 W at 8 Ω. These figures can help with initial system planning, but the specifications supplied here do not describe every allowable wiring configuration or provide a recommended speaker arrangement. If you are planning several speakers, compare their impedance and power requirements with the intended amplifier mode, and have the complete load checked against the product documentation.

Bridged operation changes how amplifier channels are configured. The listing provides a rating for two bridged outputs at 8 Ω, but does not specify the bridging procedure, terminal assignments or any restrictions beyond that rating. Use the amplifier’s instructions to confirm which connections and settings are required. Do not assume that the terminals used in stereo mode are connected the same way in bridge mode, or that every speaker load is suitable for bridging.

The SMQ350 uses Class-D amplification and a switching-mode power supply, according to the supplied specifications. These are useful technical details when comparing amplifier designs and planning a rack system. The information provided does not state total power consumption, energy efficiency, heat output or any specific operating advantage. Assess those requirements separately if they matter to your installation rather than inferring them from the Class-D designation alone.

The listed frequency response is 20 Hz to 20 kHz within ±3 dB. This gives a reference for evaluating the amplifier’s specified frequency range. The result heard through a complete system will also depend on the speakers, source material, connections, settings and room. If a project has specific signal or frequency requirements, compare them with the amplifier’s supplied specifications and check the rest of the signal chain as well.

The signal-to-noise specification is greater than 95 dB. Total harmonic distortion plus noise is listed as less than 0.05% at 1 kHz and half rated power. The measurement condition matters: the THD+N figure is specifically associated with that frequency and operating level. Use these figures for comparison on a like-for-like basis, and avoid treating them as a guarantee of identical performance at every load, frequency or output level.

Crosstalk is listed as greater than 70 dB at 1 kHz, and common-mode rejection ratio is specified as 70 dB. Damping factor is listed as greater than 200. These values can assist technical buyers comparing amplifier specifications, but the supplied details do not explain all test conditions or measurement references. If any one of them is critical to a system design, check the manufacturer’s documentation for the applicable conditions and how the figure should be interpreted.

Balanced input impedance is specified as 10 kΩ. The listed input connectors are XLR and a 3-pin Euro terminal block with 3.81 mm spacing. These connection options are relevant when matching the amplifier to source equipment, signal cabling and an installation’s wiring plan. Confirm which input type suits your equipment and how the terminals are assigned. The supplied details do not identify how many of each connector are provided or specify a particular input-routing arrangement.

Input sensitivity is entered in the supplied specifications as “−19.5 dB ~ 27 dB.” The reference and exact interpretation of this notation are not explained. Before relying on the figure for gain structure, check the product documentation or ask BME to clarify what the stated range represents. Do not assume that the values are in dBu, that they describe a particular gain-control range or that they use a specific reference level unless confirmed.

The output connections are described as Speakon-compatible connectors and 2-pin Euro terminal blocks with 5.08 mm spacing. The listing does not state the number or assignment of each output connector. Check the rear-panel labels and product instructions to determine which terminals correspond to the intended channels and operating mode. Also confirm that the speaker cable and connectors you plan to use match the amplifier’s actual outputs. Do not assume that cables or speaker connectors are included.

Protection features listed for the SMQ350 include amplifier DC, short-circuit, overheating and overload protection, along with signal limiting and a loudspeaker power limiter. These are relevant points to review when choosing equipment for a fixed installation. The supplied information does not explain each protection threshold, response or operating condition, so do not treat the list as a guarantee against every fault or incorrect connection. Follow the manual’s setup, ventilation and load requirements to support safe operation.

Access is described as having User and Administrator levels, with password and USB-key protection. The supplied details do not explain the available settings, how the USB key works or whether access is local or remote. Confirm those details if access control is important to your installation. The feature listing does not establish network management, remote monitoring or a particular software platform, so do not assume those capabilities from the access-level description.

Cooling is specified as a temperature-controlled fan. The listing does not provide fan-noise figures or describe how the fan behaves under different operating conditions. When planning a rack location, consider ventilation and the manufacturer’s clearance instructions. Do not obstruct the amplifier’s ventilation paths or place it in an enclosure without checking the required airflow. If the amplifier will be installed near a quiet listening or recording area, ask for any available information about fan operation and noise.

The operating temperature is listed as 0 °C to 40 °C at 95% humidity. The supplied information does not clarify the humidity measurement conditions or whether the figure assumes a non-condensing environment. Check the product documentation against the conditions at the installation site. Do not interpret the temperature and humidity entry as an ingress-protection rating or evidence that the amplifier is suitable for a damp or exposed location.

The listed AC input is 100–120 V or 220–240 V at 50/60 Hz. The information does not state whether voltage selection is automatic, manual or determined by the supplied unit’s configuration. Confirm the exact mains-input requirements and any selection procedure before connecting the amplifier to a power source. For a Bangladesh installation, ask BME to confirm that the specific unit’s power configuration matches the intended site supply; do not assume that a unit accepts both ranges automatically.

Rack planning is supported by the listed 19-inch mounting format and 2 HE unit height. The amplifier measures 482 × 88 × 420 mm (W × H × D) and weighs 8.1 kg. Use these figures to check the rack space, cabinet depth, access and support required for installation. Allow for cabling and the manufacturer’s ventilation clearances as well as the amplifier’s listed dimensions. The supplied details do not state whether rack hardware is included, so confirm the package contents if you need mounting accessories.

The construction is specified as steel, and the amplifier is listed in black. These details can help when matching the unit with other rack equipment or planning an installation. The product information does not state a front-panel layout, display, controls or included accessories. If those aspects matter to your operation, check the product documentation or ask BME to confirm them for the exact model.

The SMQ350 may be considered for installed sound systems that require multiple amplifier channels in a rack-based setup. Potential environments could include commercial spaces, meeting facilities, hospitality venues or other sites where a system designer has specified suitable loudspeakers and amplification. These are possible contexts for evaluation, not a guarantee that the amplifier will fit every venue. The appropriate choice depends on speaker loads, required output, signal connections, rack space, ventilation and the installation’s power requirements.

For a multi-channel system, plan how each amplifier output will be used and which speakers it will drive. Confirm whether the intended setup uses stereo or bridged operation, check the ratings that apply to that mode and verify the speaker impedance. A four-channel amplifier does not, by itself, determine the number of speakers that can safely be connected. The complete system load and wiring must be checked against the amplifier and loudspeaker documentation.

The “WaveDynamics” name appears in the product title, but the specifications supplied here do not enumerate any processing, equalisation, network or control functions beyond User and Administrator access. If you are considering the amplifier for a workflow that requires a specific digital signal-processing feature, preset, remote-control method or software integration, confirm that feature for the SMQ350 before purchasing. Do not infer specific DSP capabilities from the model name alone.

Before ordering, also check the exact input and output connections your installation requires, the input-sensitivity notation, mains-voltage configuration, rack depth and ventilation needs. Confirm that any required cables, connectors or rack hardware are available for the planned setup. The supplied details do not include a warranty period, country of manufacture or package contents, so ask BME to clarify any of these items that affect your purchasing decision.

The Audac SMQ350 is best evaluated by matching its rated output modes to the speakers and system design, then confirming the signal connections, mains input and rack requirements. Its four-channel configuration, Class-D technology, protection features, balanced input impedance and listed response measurements provide useful comparison points. Careful checking before purchase can help determine whether this amplifier suits the intended installation without assuming unlisted functions or connection arrangements.
