VivoLink PA250 Audio Amplifier 2x50W (Class-D) with IR & TCP/IP

Total number of physical audio input connectors (left/right) available on the product, such as RCA or optical jacks. The value is an integer representing how many separate input points can be used to connect external audio sources.

Indicates the total number of independent audio channels that a product can produce or process, including sub‑channels such as those used in surround sound configurations (e.g., 5.1, 7.2). The value may be an integer or a decimal to represent fractional channel groups.

Indicates whether a speaker or audio device has a bass adjustment feature that allows the user to increase or decrease low‑frequency output. A value of "Yes" means the device supports this control, while "No" indicates it is not available.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

The electrical potential difference that a device is designed to accept from its power source, expressed in volts (V). It indicates the nominal operating voltage for the product and helps users verify compatibility with local mains or battery supplies.

The span of frequencies, expressed in hertz (Hz), that a device can operate within or respond to. It may be given as a single value, a numeric range (e.g., "20 000‑50 000 Hz"), or an open‑ended interval such as "2.4 GHz+" indicating the lower bound only.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

Indicates the types of headphone or earphone connections available on a product, such as wired jacks (e.g., 3.5 mm), USB‑C, Lightning, or wireless Bluetooth. The value may list one or more connection types separated by commas.

The highest electrical current that a device can safely draw from its power source, expressed in amperes (A). It indicates the maximum load the product is designed to handle during normal operation and helps users verify compatibility with power supplies or sockets.

The primary purpose of a product, indicating its main intended use or target market segment (e.g., "Gaming", "Office", "Travel"). It helps customers quickly identify whether the item matches their needs and can be used for filtering or categorization across different product categories.

The method or mechanism used to operate a device remotely, such as infrared (IR), Bluetooth, Wi‑Fi, radio frequency, or wired connections. It indicates how the user can send commands to the product from a distance.

The ratio of the desired signal level to the background noise level, expressed in decibels (dB). It indicates how clearly a device can transmit or receive audio or other signals relative to unwanted interference. A higher value means better clarity and fidelity.

The overall distortion introduced by a device, expressed as a percentage of the total output signal. It represents the ratio of all harmonic components to the fundamental frequency and indicates how much the waveform deviates from a perfect sine wave.

Indica el mecanismo o método con que se opera la función de ajuste de volumen en un producto, como botones físicos, controles giratorios, táctiles, digitales o combinaciones de estos. Los valores comunes incluyen "Tocar", "Botones", "Giratorio", "Control en línea" y otras variantes similares.
