The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other LED, QLED and OLED TVs plus TV mounts, streaming media players, antennas, cables and satellite gear we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Insignia NS-DXA1 bridges the gap between older analog televisions and the current all-digital over-the-air broadcast landscape. Insignia is Best Buy's house brand, and this converter box has found a steady audience among cord-cutters and households keeping vintage TVs in secondary rooms.
The Powerline connectivity listed in the specs is an unusual feature for this category, suggesting this unit may include provisions for sending a signal through your home's electrical wiring rather than requiring a direct coax run. That can be useful when routing a cable is not practical.
At $90.13 it costs more than basic converter boxes, which typically run $30 to $50. The higher price may reflect the additional connectivity features or current market availability. Weigh that against buying a modern budget TV if the existing set is already aging.
Pros
- 4.2 stars across 210 reviews shows consistent buyer satisfaction
- Powerline connectivity option useful for installs without a direct coax path
- Trusted Insignia brand backed by Best Buy retail support
- Weighs only 1.7 lb, easy to place near any TV
Cons
- At $90.13, this costs significantly more than basic converter boxes
- No HDMI output listed, so connection to the TV depends on the available analog inputs
- Limited spec detail makes it hard to confirm all supported features before buying
Performance notes
Weight is listed at 1.7 lb, indicating a compact unit. Connectivity is noted as Powerline, which distinguishes this from standard coax-only converters. No HDMI port count is published in this listing. Reception quality will depend heavily on antenna placement and local broadcast signal strength rather than the converter itself.
What buyers say
With 210 reviews averaging 4.2 stars, buyer sentiment is broadly positive. This suggests the unit performs reliably for its intended purpose. Complaints in this product category generally relate to antenna setup or weak local signals rather than the converter box itself.

Frequently asked questions
Will the Insignia NS-DXA1 work with any old TV?
It is designed to work with analog TVs that have standard composite or coax inputs. The converter receives digital over-the-air signals and outputs them in a format the older TV can display. You will still need a separate antenna connected to the converter box.
What does the Powerline connectivity do?
Powerline technology lets a signal travel over your home's existing electrical wiring. In a converter box context, this can allow you to distribute the TV signal to other rooms without running a dedicated coax cable, which makes installation simpler in some homes.
Do I need a converter box if I already have cable or satellite?
No. Converter boxes like the NS-DXA1 are specifically for receiving free over-the-air digital broadcasts on older TVs that lack built-in digital tuners. Cable and satellite services provide their own signal decoding through the provider's equipment.
