High level input and monolithic poweramp

Akeel Shah · 5 Oct 2020 at 17:06

So I have a Denon Poa t2 monolithic poweramp meaning the left and right channels have their own amplifier circuits. it has channel a and b selection and a powerbutton thats all on the front and on the back the speaker terminals and an Rca for each side... I used to run 2, 10 inch subs with my old avr which blew thus the need for my poweramp and also i hate home theatre filtering id rather have a raw signal and in the future a dac ... but as i have been researching if i was to get a high level input cable and subwoofer the connection is made from the positives of my channel b and ground. other end into the subwoofer im looking at the Rel r9i or something like thst with high level input my question is will it cause any issues because the power amp has two amplifiers internally one per channel. I really want to get the Rel sub it looks like exactly what i want but i also wouldn't want to blow my Denon Poa t2 its my first poweramp and im loving it so far just miss the love of sub bass . thanks for reading thru.

na the subs i used to have i had a separate monoblock car amp and i had it plugged into my old av via the subwoofer out.. since that died i bought a poweramp for my mains so left and right speaker is in channel a left and right terminals... i have channel b left and right free so i was hoping to get a rel subwoofer and do speaker level connections so use the power amps free left and right (channel b) and inputs for the high level out on the rel .. my consern now is if there would be that hum sound since the power amp is monolithic so has two amplifiers inside. so i may have to buy 2 subs from rel and have one for the left channel b and the second sub right channel b

the subwoofers were car subs so passive but powered by the pioneer 9601 so about 1200rms true power but as i want to use rels now that setup doesn't matter but it worked well

i also thought it would be abit risky so i ordered a emotiva pt100 preamplifier which has a standard subwoofer out...
it also has lots of digital inputs nice for pc or any device really also when i used to use my car subwoofer amp it barely created much heat (class D) and sounded great hum was a hit or miss depending on sockets etc however i fixed the issue by grounding the RCAs with this there was zero hum and the preamplifier allows for me to later down the line buy a rel subwoofer and connect to the low level input via rca perfect im so excited
