Heritage Audio OST-4 V2

I wanted in to the 500 Series world and so I began my research.

I knew I wanted SSL modules, and other Class A preamps that require solid power. I also didn’t want to introduce power supply noise to adjacent modules so an external P/S seemed like a right fit for me.

I didn’t want to commit to 8 or 10 slots straight away, and I wanted to build channel strips through linking slot inputs/outputs on the box without requiring patch cabling.

The Heritage OST-4 V2 perfectly met all my needs and Thomann exceeded my expectations in service and support.

I unreservedly recommend this box!

This is my first experience with a 500-series rack case; before that, I had a 19-inch version. This is also my first comment on Thomann. I'll be brief: I received an asymmetric case, and I can’t insert more than one module into it in a way that allows it to be screwed in afterward. No matter what I tried, nothing worked. Measuring the levels revealed a discrepancy in the bolt hole alignments of more than 1.5 mm. This is how a well-known brand with a good reputation let me down. The experience was somewhat spoiled, but I’m not discouraged and will buy another rack case from the same manufacturer.
