Heritage Audio OST-4 V2

Awesome lunchbox!

Very quiet and stable! I'm buying another one! Recommended!

Sturdy and with enough power

Very solid and provides more than enough juice to feed a couple of preamps with transformers and a stereo compressor with transformers and valves.

I'm very happy with it.

Ideal size for Vocal Signal Chain

Having my first 500 Series is a good experience.

The unit is a neat and tidy size, solid unit, secure slot fit for each unit also.

Great to have rear buttons to send signal rather than rely on patch leads - although still totally easy to patch out to DAC at any slot.

Have not detected any unexpected noise as yet in the signal, so happy with the purchase. Recommend for 4 module signal chains.

Works like it should

Everything works well with this unit. There is not much to say about the functionality, it simply does what it does. I have nothing to compare it against as it is my first rack unit, but overall I am happy with it. The green lights give it a lovely aesthetic when on. The only annoying thing is that there is no power-on switch, but it is not a dealbreaker. Small, aesthetic, and a good way to get into 500 modules

Great Lunchbox

My first 500 series lunchbox.

I am very happy with this purchase. This is a lunchbox which holds 4 500 series modules. Which is perfect for me and I intend to fill it with mic pres.

Its a simple design you slot your modules in and their ready to go. The power supply is external and will power your modules. its very well built, a metal chassis that is very robust.

All in all its perfect if your looking to start using 500 series modules
