Overview
["The TX-SR373 sits at the entry end of Onkyo's AV receiver lineup, measuring 14.5 x 17 x 13.38 inches and weighing 17.6 lb. It carries a 155W output rating and four HDMI inputs alongside a Bluetooth connection, covering the primary connectivity needs of a basic home theater without reaching into mid-range pricing.", "With 419 reviews at a 4.1-star average, the TX-SR373 has a credible feedback base. For an entry-level receiver the rating is respectable, and Onkyo's brand recognition in AV equipment gives it more credibility than comparably priced units from lesser-known manufacturers.", 'The key distinction from the budget 2-channel receivers in this space is that the TX-SR373 offers multichannel surround sound processing, four HDMI inputs for connecting a Blu-ray player, game console and streaming device simultaneously, and the Onkyo build standard. Buyers looking to graduate from a soundbar or a stereo setup to actual surround sound will find it a reasonable starting point.']

Frequently asked questions
How many speakers can the Onkyo TX-SR373 support?
The TX-SR373 is designed for surround sound configurations beyond simple stereo. The specific channel count supported is not published in the available spec data, but as an Onkyo entry-level AV receiver it is built for multichannel layouts. Check the product listing for exact speaker terminal counts.
Does the TX-SR373 include room calibration?
Onkyo entry-level receivers in this class typically include basic auto-calibration, but the depth of that system is more limited than what you find on mid-range models with Audyssey or similar advanced processing. For a first home theater setup it should still help with basic speaker level matching.
Is the Onkyo TX-SR373 compatible with 4K TVs?
The available specs do not confirm 4K HDR passthrough certification for this unit. Given its positioning as an entry-level model, buyers with 4K displays should verify HDMI version compatibility before purchasing to ensure it will pass their video signal correctly.
