There is no sound or display on my amp but it is getting power because my tuner is pluged in the back and it works


It is possible that you have a blown internal fuse as I think that the AC tuner power outlet is simply jumpered to the main input power to your amp.

What kind of pre amp do i need to operate my parasound HCA-2205A high current power amp


Any preamp should work. A preamp goes into your system between the amp and the other components which plug into it- CD player, FM tuner, Turntable.....etc. It's takes their output signal, processes it as my be Volume, bass, treble... and then send a sufficient signal to the amp to drive the amp to power your speakers. As long as the preamp output is enough for your Amps input any will work as most will be.

Wy fuse keeps blowing


Fuses blown when an overload occurs. More often than not caused by a short circuited transistor in the main amp section. Possibly also on the power supply too.

Carver CT-28v Tuner preamp - Has a hum/buzz (soundls like a ground loop) that is heard as soon as the unit is turned on. Does not increase with volume, just stays the same and is continuous. Changing...


Reverse the polarity of the AC plug and try it. Is there a headphone jack on the preamp? Try headphones with the preamp standalone without the amp attached.

Are you sure the preamp is the problem? I assume you also have an amp or you wouldn't hear anything. Power up the amp with nothing but speakers attached. Hum??? It's in the amp. No Hum? Attach just the preamp with no external components. Hum now? It's the CT-28. Turn it off an exercise every switch and knob throughout its range numerous times. Try again. Still humming? Manipulate source selections, Tape Monitor, everything.

I don't know where to connect the main in & pre amp jacks??? to the EQ???


Not sure I understand your question, but I will try.
Your CD players, tape decks, etc., connect to the INPUTS on the preamp.

The LINE OUT on the PRE AMP connects to the LINE IN on the POWER AMP.
The pre-amp does some amplification and then it passes the signal along to the power amp, which will do the heavy lifting - driving the speakers.
The connection is usually through a shielded RCA plug cable. THere will be 2 cables from the Pre amp to the power amp - one for the left channel and one for the right channel.
The OUTPUT Of the power amp will connect to the speakers using large, stranded wire cables, sometimes with "banana" plugs that simply plug into the terminals on the power amp and the speaker.
Let me know if this gets your started.

Connection of Amp to Equaliser


Thanks guys, but i solved my problem, i experimented and decided that i would run my DVD player (Aux Out) as a CD player through the Equaliser in [Rec] and from equaliser out [Play] i went into Tape Play on Amp, then i connected my Turntable CD Radio System to the Tape 1 Rec on Equaliser and then from Tape 1 Play on Equaliser went into the Tape 2 on AMP then i could use Aux in on Amp to connect my Laptop via my laptops headphone socket my laptop has an equaliser so i didn't need to connect to pioneer EQ, i also connected a small 5.1 to the DVD's 5.1 and connected 4 *45w Speakers to the AMP. and i can say it was FANTASTIC i couldn't get to 5 on my volume it was un @$#%believable.

Stereo connection


Hi spanky

Sorry for the delays in getting back to you. Been busy here this week.

OK. to connect the 2275 to the 1152,there are 2 ways of going about this.

You can plug the pre- out of the 2275 to the power amp-in of the 1152. In doing this you are using the power amp section of the 1152 and the preamp functions of the 2275. Your other gear like CD player, tape deck and so on also plug into the 2275.

the other(better) way is to plug the pre-out of the 2275 into the tuner inputs of the 1152, leaving the volume at about 40% on the 2275 and use the 1152 as an integrated amp. This means you are using the 2275 as a tuner only. When you do this, you will need to use an RCA lead to jumper the pre-out/poweramp-in connections on the back of the 1152, and the 2275 ... L to L and R to R respectively.

I am still wondering why you want to use 2 integrated amps (each having a preamp and a poweramp section) The only real benefit the 2275 brings to your system will be tuner functions. You could just get a tuner and run the 1152 to be an ideal rig.

Let me know what your ideal setup you are wishing to build would have. Speakers, other gear like CD, tape deck, etc.
