Question about Technics SUV500 2-Channel Amplifier

2 Answers

I got a system from a friend of mine that appears to be in great shape however, when I hooked it up I can barely hear the sound out of the speakers. I tested the speakers with another system and they were fine. If I crank the volume up to 'full blast' I can hear it but faintly. Its like standing next to someone who has ear buds in and the volume is too high, you can hear the tinny overflow but its not really music. I looked for something that would look like a fuse or switch on the outside of the case but nothing. I pressed the help/reset button and the text says system is operating correctly. Any advice is appreciated. I have it connected to a tuner and a cd player and the result is the same regardless of the source. Thanks in advance. System: Technics SU-G88

SOURCE: I can barely hear output even when the volume is at 100%

You may have the tape monitor button pushed in or if you look on the back of the unit you may find a pre-out/main-in set of rca jacks. If you don't have a switch to bypass those jacks then you will need to use a set of 2 RCA jumper cables or some stubs made for that purpose. Hope this helps.

Just hooked up Coax cable; now talking is barely audible


is the center speaker turned up in the reciever speaker settings? each speaker can be adjusted to a level that is higher or lower or all the same as the rest. also is the dolby digital turned on in the reciever settings? and changing the surround sound pre set sounds can also improve the type of audio you are listening to in 6.1 surround sound

i think your computer audio is not in shape to boost a great sound. specially when it is built-in sound in the motherboard of your computer. see your computer / motherboard manual's if the driver's you have AC '97 then you cannot really boost sound.coz it's a generic driver's for sound card. if try also to update your driver's (sound). by seeing the brand and the model of your motherboard or computer and go to manufacturer websites for update. after update if can't help, but you really need to boast a great sound then you can really buy a PCI sound card 6 channels or 24bit 5.1 or 24bit 7.1 f your sound system have are compatible with this. or has an interface like this - audio 5.1 and 7.1.

Great sound, no voices


Mine was the center speaker wire was not properly seating in the speaker. This is where all the sound for the voices come out. I thought it was something major. try checking them again if you haven't already.

I'd make sure that the receiver surround mode is set for one of the digital settings, such as Dolby Digital or DTS, and make sure that you have the center channel level adjusted to a level similar to the other two front channel speakers. I've seen/heard this happening when using dolby digital material & having surround set on something like 'hall' or 'stadium' or dolby surround, where only 4 channels are used & the amp has to 'mix' sounds to the left & right front speakers. It'll often sound like the actors on screen are talking out of the bottom of a barrel, with a hollow & tinny character to the voices.
