The AR-133 is used to convert an unbalanced instrument signal into a balanced XLR signal for connection to a mixing console or related audio equipment. It is intended for live sound engineering and can also route a parallel output to stage amplification equipment. The exact input, output and installation configuration should be confirmed for the selected model specification.

Yes. The product information states that the AR-133 accepts standard phantom power. It can also automatically switch to internal battery power. Phantom power should be supplied only by compatible equipment and used according to the system design. Confirm the selected model specification, power requirements and battery details before using the unit in a specific installation.

The AR-133 includes internal galvanic isolation and a ground lift switch. These functions are designed to help eliminate or reduce ground-loop noise when connected equipment has unwanted electrical interaction. Actual system performance also depends on cables, power distribution and other devices. Confirm the selected model specification and test the complete signal chain during installation.

The product description identifies high-impedance acoustic guitars as a supported use case. The unit accepts an unbalanced instrument connection and provides a balanced XLR signal for the mixing system. Use the attenuation pad when appropriate for the source level. Confirm the selected model specification and connector requirements for your guitar, cable and console.

The product description states that the switchable attenuation pad accommodates powerful synthesizer signals. This helps users select a more suitable level before sending the balanced output to the mixer. The correct setting depends on the source and system gain structure. Confirm the selected model specification and the synthesizer output requirements before connecting the equipment.

The available product facts describe the AR-133 as an active D.I. box for signal conversion, balancing, isolation and live sound routing. They do not document USB connectivity, computer compatibility, recording software, sample rates or digital inputs and outputs. If computer recording is required, confirm the selected model specification or ask YH-AUDIO about a suitable separate interface.

The documented workflow is to insert the unbalanced instrument cable, select the appropriate attenuation-pad setting, use the ground lift when needed and send the balanced XLR signal to the mixing console. A parallel output can feed stage amplification equipment. Confirm the selected model specification, connector layout and power procedure before final installation.

The AR-133 is presented as an Active D.I. Box within YH-AUDIO audio-interface category data. For merchandising, it should be positioned around live sound signal conversion, balancing, galvanic isolation and ground-loop control rather than as a documented USB recording interface. Confirm the selected model specification, retail classification and market labeling requirements before listing.

The documented features include standard phantom power support, automatic internal battery switching, internal galvanic isolation, ground-loop noise reduction, a switchable attenuation pad, high-impedance acoustic-guitar handling, balanced XLR output, parallel output and ground lift. Weight, dimensions, materials, electrical ratings and other technical values are not provided. Confirm the selected model specification for quotation documents.

Its stated live sound function and connections to mixing desks and stage amplification equipment make it relevant for rental, event and production inventories. However, procurement teams should not assume durability ratings, certification, replacement-part availability or warranty terms. Confirm the selected model specification, packaging, service process, quantity and destination-market requirements before committing stock.

The AR-133 supports standard phantom power and automatically switches to internal battery power according to the product description. The available facts do not state battery type, battery life, voltage range, phantom-power voltage or replacement procedure. Confirm the selected model specification and request the applicable technical documentation before preparing a wholesale offer or user guide.

The current product facts describe an unbalanced instrument input, balanced XLR signal routing and a parallel output, but they do not confirm optional connector layouts, materials, enclosure construction or customized hardware. Distributors should specify the required configuration, quantity and destination market, then ask YH-AUDIO to confirm the selected model specification and available sourcing options.

The product facts do not confirm OEM branding, private-label packaging, custom colors, manuals or hardware changes. These may be procurement questions rather than established product features. Distributors should provide the target market, order quantity, branding requirements and packaging language, then obtain confirmation of the selected model specification, MOQ, lead time and commercial terms.

YH-AUDIO identifies the required function or configuration, material or build requirements, quantity, destination market and target price level as quotation inputs. Buyers should also specify connector expectations, packaging, warranty needs and any language requirements. Because several commercial and technical details are not listed, confirm the selected model specification before comparing supplier offers.
