Confused - Biwiring / Biamping

[Mayank Shah]

From what I understand, bi-amping is the use of 2 separate amps for 1 pair of speakers and bi wiring is using 2 pairs of wires from one channel for one speaker for the low and high.

My Polk RTi A7 has dual binding posts.....good. So as per Polk manual, we have to remove the jumper plate, connect 2 pairs of wires from the amp to the upper and lower binding posts per channel. It does not matter which is up or down as they merge at the amp's binding post (Branch out from the amp).

Now reading Marantz technical literature, quote " Marantz has 2 sets of speaker outputs which can be used for bi-wiring or bi-amping a pair of speakers"......hmm so now what should infer from this ???

So does it mean

1. Speaker A Left going to left speaker bottom post / Speaker A right going to left speaker upper post and similarly speaker B outputs for the right speaker

OR

is there any other way to utilize both speaker A and B outs for 1 pair of 3 way speakers (like the Polk RTi A7).


I have a NAD 356 with DAC and it has 2 sets of speaker outs.

Off the topic a bit, how can I playback my Flac files from the laptop to the amp wireless?

Eagerly hoping for FM's suggestions. Many Thanks in advance.

HI,

Bi Amping means that you need two amplifiers per channel one for LF and one for HF.
So for left channel there is one amp for Low Freq and one for Hi Freq.

Some 7.1 channel Onkyo receivers allow you to use their seventh channel L+R for Bi amping.


Bi Wiring is just running 4 wires to the speakers from the 2 binding posts of the amplifiers.

For BiAmping you need 4 Separate amps.
For BiWiring you increase the number of wires going to the speakers.

This article shows how to do it.

for playing wireless... this can be an option

Crystal Audio - Crystal Audio - BluDAC - Bluetooth: Amazon.in: Electronics

and Arcam has irDAC too but maybe NAD has something that connects to your onboard DAC and makes it wireless..

Biamping helped me improving 25% performance/SQ of my Wharfedale

Speaker A and B means the amplifier has two sets of speaker binding posts that can be connected two pairs of speakers. You can operate either A or B at a time, not both. So A/B function is not usable for biamping since physically there is only one amplifier.

Hello mpw,

I ordered the same one from Amazon, it works great with all the phones and mp3, but with FLAC from the laptop there was a lot of jitter and a difference in the SQ. I returned it and came across 2 of their other products:

WiDAC - WiFi Audiophile DAC - CRYSTAL ACOUSTICS GREECE: Amazon.in: Electronics

Wi-DAPTOR- Wireless Multiroom Adaptor - CRYSTAL: Amazon.in: Electronics

Hope to check them out after seeing the difference in specs.

Thanks. Good day.

what also works and gives and audible difference imo is taking out the jumper plate and using copper speaker wire to connect it.
