## At a glance

- Built-in two-channel mixer is described for microphone, line-level, and Bluetooth inputs, with a mix output for linking speakers.
- Bluetooth True Wireless Stereo is described for pairing two units for stereo playback.
- The manufacturer claims up to 10 hours of battery-powered operation. Actual runtime may depend on use.

## Pros

- Battery operation can help when performing or presenting in a space without convenient power.
- Bluetooth plus XLR/TRS and other listed audio inputs provide several ways to connect sources.
- A listed mix output and TWS pairing support different multi-speaker setups, though TWS requires another unit.

## Cons

- At 13.3 kg and 15 x 13.5 x 23.7 inches, it is a sizable speaker to carry compared with compact portable speakers.

## Before you buy

- The listing describes a two-channel mixer and simultaneous use of two audio inputs, but its connection details include several input types without clearly mapping them to mixer channels. It also lists 20 KHz as frequency response without a range, and the 10-hour battery figure is a manufacturer claim without stated test conditions. Confirm the specific connections and runtime expectations for your setup.

## In the box

- TX412B speaker (Included)
- Power cable \(6 ft. / 183 cm\) (Included)
- Quickstart guide (Included)
- Safety and warranty manual (Included)

## A good fit for

- Performers, mobile DJs, and speakers who need battery-powered PA sound where mains power is limited.
- Users who want Bluetooth playback alongside a microphone or line-level source.
- Buyers planning a floor-wedge setup or a pole-mounted arrangement, with pole mounting hardware not confirmed in the package list.

## Less suited to

- Buyers seeking a lightweight, compact speaker for frequent long-distance carrying.
- Users who need a confirmed battery runtime under a particular volume or performance condition.

## Customer feedback

Aggregate ratings lean positive, with many five-star ratings, but a substantial one-star share makes the overall picture mixed. The ratings do not explain why customers chose them, so they cannot establish battery runtime, sound quality, or reliability. For buyers considering this battery-powered 600-watt PA speaker, the listing's up-to-10-hour runtime remains a manufacturer claim rather than a customer-verified guarantee here.

## Frequently asked questions

### How long does the ALTO TX412B run on battery?
The listing claims up to 10 hours. It does not specify the operating conditions behind that figure, so treat it as a manufacturer estimate rather than a guaranteed runtime.
### Can it play music while a microphone is connected?
The listing describes simultaneous use of two audio inputs and a built-in two-channel mixer for microphone, line-level, and Bluetooth sources. Confirm the input and channel arrangement for your intended setup.
### Can the TX412B be used on a speaker pole?
The listing mentions pole mounting and an integrated 36mm pole socket. The explicit package contents do not name a pole or stand, so those should not be assumed included.
### Can it connect wirelessly to another speaker?
The listing describes Bluetooth True Wireless Stereo pairing between two units. A second compatible speaker is needed, and it is not included in the listed package.
