Question about Adcom GFA-5400 2-Channel Amplifier

2 Answers

Adcom GFA-5400 installation

There is only one set of speaker outputs on this amp, can I hook up multiple speakers to the single set of terminals or do I need to use something like a Niles MSA-10A. The only issue that I have with it is that I fear that sound quality will suffer, plus I have two sets of small Energy speakers and then a larger pair of MKs that I want to hook up. How do I hook up a sub to this?

    Will the Niles compromise sound quality?

Use the niles for more than one speaker hookup. As far as the sub hookup, use a powered sub with speaker inputs
then use the right or left speaker and tag a couple wires to the sub. Good Luck

How do you connect wiring to bridge an adcom gfa 5300?


The manual does not specify a bridging option.

http://www.audioreview.com/cat/amplification/amplifiers/adcom/gfa-5300/prd_116265_1583crx.aspx

"Weaknesses:
Not bridgable."

Generally an amp that IS bridgeable uses the positive speaker terminals and some switching method to tell the unit to run as bridged. This is NOT a recommendation to try it on the 5300.

Do you mean Adcom? That detail matters.

That would mean you're trying to run two rooms with paired mono speakers and a different channel in each room. MMmm, okay.

It's a 2-channel power amp and it isn't really designed for the probable very low imedance you're providing with paired speakers on each terminal. And it has no ability to turn either channel on or off short of denying it a program input on either channel.

Perhaps if you ran one speaker from each channel into each room (impedance permitting), you would have two rooms with traditional 2-channel audio.

Convert a 4 om amp to play w/8 om speaker


Connect the two speakers in parallel. That will present a 4 Ohm load to the amp.

Adcom GFA-5002 is dead no lights, no anything


Check the Fuse. Unplug the AC first. If you replace the fuse and it blows again, disconnect all speakers, replace the fuse and turn on. If the fuse does not blow, chances are it is a speaker problem, Adcom builds some very solid product, I would suggest pulling the outdoor speakers and testing them.
Depending on what you are using, some outdoor speakers should never be taken out of the living room. If you still have an issue post a comment and I will help some more.

How do i bridge an adcom gfa 5400


This amp is not designed to be bridged and can not be used in the mode you wish. Sorry, but internal circuit changes would be necesary for the amp to work as a single channel.

Try just the power amp on ..nothing connected
no Dakiom thingy either. It's a matter of elimination. Start at the output device and work back. Keep the Dakiom out of the loop.
If there's hum with just the Adcom..then it's the ADCOM
