Usually, Marantz AV receivers have a fairly simple and understandable "name". The letters are the receiver series. Then 2 digits — the model number. The last digits are the year of release (individually for each series).

Consider an example:


1. SR receiver with volume sound;

2. 70 is the model in the series (the higher the number, the higher the receiver class);

3. 15 — Year of manufacture (15 — 2020, 14 — 2019, 13 — 2018, 12 — 2017, 11 — 2016, 10 — 2015).
