I've been asking them similar questions since February. I follow up every month or so and they come back to say that it's with the tech team or the R&D team but they're very busy. Seems to me that they don't want to share. This is the email I sent on 2 February. There's been 10 subsequent email exchanges, with the last one telling me that responding to this is not a priority:i emailed them back on July 30th, but still haven’t received a response.
Hi Blackstar,
Hoping you can provide information about signal strength for the Blackstar Unity Pro Bass range please:
1. What is the signal strength from the Cabinet Link Output of the Unity Pro Bass series amplifiers?
2. What is the minimum and maximum signal strength that can be sent to the Unity Pro Bass ACT250 Active Cabinet - via the Cabinet Link/Line Input - from an external source?
3. What is the optimal signal strength for the Unity Pro Bass ACT250 Active Cabinet to receive into the Cabinet Link/Line Input - from an external source?
