4 slots 500-series using On Slot Technology and built-in link switch to connect adjacent slots.

The Heritage Audio OST-4 2.0 is a 4 slots 500-series using On Slot Technology and built-in link switch to connect adjacent slots.

The Heritage Audio OST-4 2.0 delivers power to each slot individually, with each slot using its own dedicated power supply linear regulation stage. This allows each module to be completely separated and perform at its optimum independently avoiding issues associated with sharing power between different modules. Phantom power is available via the chassis to work with preamps and condenser microphones.

The new Link feature lets you connect a slot to the next at the push of a button, removing the need for patch cables

Each slot has test LEDs to ensure proper power operation and offers a maximum power capability of 400mA per rail per slot with an overall 700mA per rail. The chassis is made of heavy gauge steel with an aluminium front panel and proudly sports Heritage’s typical RAF Blue Gray.
