Question about Gem Sound GemSound PA-585 2-Channel Amplifier

1 Answer

Gem Sound xp-350 power amplifier.

Port lights come on almost immediately after power up with or without input source connected. Amp is being used to power small monitor speakers. Audio source is my laptop itunes library connected to a 12 channel Yamaha mixing board. Mixer sends signal from monitor out L/R to input jacks L/R on amp. Port lights shut down all audio when they come on right after power up. If I power off the amp and let it reset it will come on for a couple seconds, then port lights come on both channels and audio shuts down.

    hen you say "port" lights,are you referring to "prot" or protection lights? If you have protection lights engaging, there is a fault in either the amp or the speaker/wiring. If the problem is still there with the speakers and cables disconnected, then the fault is in the amp and will need a tech to take a look at it for you. If things seem normal with the speakers disconnected, then there is a fault in the speakers/connectors or wiring associated with them. You will need to do some checked with an ohms meter to look for short circuits, Happy to answer any questions you may have about this. Good Luck

Onkyo ht-rc180 standby light blinks will not start.i tryed factory reset, still blinks


The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

I have a velodyne sub woofer needs amp power source I have a kenwood eq and a sony reciever trying to figure out how to hook it all up right


So, you don't have a powered Velodyne sub (with a built in amp?)

Without model numbers - I"ll guess that there are speaker in and out connections on the back of the sub.

You simply connect the left and right speaker wires from the receivers to the subwoofers input speaker wire connections.

Then connect your main speakers from the sub's Out (or "speaker"} connections so that the sub is in line with the speaker path.

Use the sub's crossover settings on the back till you hca a seamless blend of the sub to the speakers where it is hard to tell you have a sub other than you your music now has deeper bass.

Why do you need the Kenwood EQ? This is not a necessary piece as nobody really knows how to use it properly and it realy complicates how you use your system. Flashing lights look cool though, right?

If you really must complicate the operation of your system then connect the Tape output of your receiver to the tape input of the Kenwood EQ, Then connect the Tape output of the Kenwood EQ to the Tape input of your receiver - assuming your receiver even has tape ins and outs.

You can engage the Kenwood EQ by inserting it into the audio path when you select the appropriate Tape input as the source on your receiver.

Hope this helps.

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

I dont know how to connect my gem sound trf152 speakers


Looks like it takes regular home theatre speaker wire. If this is a powered speaker (like a JBL eon g2), then all you need is a passive mixer, and connect the speakers to the mixer. If this is not a powered (amplified) speaker, then you will need an amplifier to boost the sound source and drive the speakers, so you would connect the mixer to the amplifier, then the amp outs to the speakers.

What if went in safety mode, safety mode is froze in screen. Won't do anything


"Safety" mode - literally? I don't see that anywhere in the manual.

Page 13

Speaker Connection Precautions

(North American and Taiwan models) You can connect speakers with an impedance of between 6 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp protection circuit may be activated.

Page 66

The STANDBY indicator flashes red


The protection circuit has been activated. Remove the power cord from the wall outlet immediately.

Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and set the volume to maximum. If the AV receiver stays on, set the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your Onkyo dealer.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

WHY MY AMP STILL CLIPPING EVEN IF I KEEP IT IN A


Pleae check to see if you have over loaded the output with a wrong impedance . If so try to test the speakers and connect accordingly.
Next please check if the input source is bringing in poor signals with noise. try to cut off the hig and low freq to set the treble and bass in mid position. next use a ggood ground to take off any transcient voltage on the body due to any leakage in the power circuits. next you can disconnect and opne the panel and check for dry connections, loose connectors or poor filtering in signal processing or power circuits. If you notice any hum check this out. I hope this helps. Good day

Connect a monitor to a yahama HTR 5660 receiver


"trying to connect multiple devices to a yamaha receiver if I am using an S video to connect the tv (monitor) to the receiver do I plug it into the monitor OUT s video or would it be Input not output?" Input on the Monitor from Video Out on the Yamaha.

"if I am only using the monitor for video and not sound do I still need to plug in the audio cords or do i leave them out " - Presumably the monitor doesn't have speakers or audio connections, so it's a non-issue. Your video sources should have audio routed to the receiver. If the monitor has speakers I would also send 2-channel analog audio to it from, say, the cable/satellite box, so you could hear the weather or other lo-fi video without turning on the Yamaha.

Protect light comes on, no power


Hello patrick_h_mi,

You'll also need a remote turn-on source for the amp to operate. Normally, this is a blue or blue/white wire from your head unit, but for test purposes, you just need 12V to the "remote" terminal on the amp. The amp should power up without speaker inputs or speaker connections, but it is not recommended.

Hope this helps.
