BRAND: Bryston 

MODEL: 4B Cubed 

FUNCTION: Power Amplifier 

PRODUCT DESCRIPTION: This listing is for a Bryston 4B³ (4B Cubed) Pro Power amplifier in a custom white finish with green LED's and custom output gain trim pots. The standard model does not include those and they allow the engineer to dial in the exact amount of gain going to their monitors from the amplifier.

This amplifier was customer-ordered from Bryston a year ago and was received in June 2023. The buyer in that time had a change in their monitoring set-up and no longer required this amplifier. This is a rare opportunity to get fully kitted out Bryston that is sealed in the box with no "special order" wait time!
