Questions about the Roksan Caspian 4G Power Amplifier
Can I use two as mono blocks?
Yes. Bridged, each one gives 420 W into 8 ohms or 630 W into 4 ohms, one per speaker.
What do I need to go with it?
A pre-amplifier, or a streamer with a volume control, in front of it. It’s designed for the Caspian 4G Streaming Pre-Amplifier.
Will it drive my speakers?
At 105 W per channel into 8 ohms and 200 W into 4 ohms, it drives most speakers with ease, and bridged mono blocks handle the hungriest. Ask us if you’re unsure.
