How does one split a two-channel audio into two or three amplifiers?

Question

All home audio is two-channel, regardless of what salesmen tell you "surround sound" means. I have a 2-channel pre-amp, the output from which goes into a 500-watt power amplifier, output of which goes to my speakers. How can I "split" those two pre-amp output (RCA cables) into four or six, so that I can add additional power amplifiers and more speakers?

All home audio is two-channel, regardless of what salesmen tell you "surround sound" means. Ah, well some moves are 5 channel, but I rarely turn my high def TV on.

ANYWAY I have a 2-channel pre-amp, the output from which goes into a 500-watt power amplifier, output of which goes to my speakers. How can I "split" those two pre-amp output (RCA cables) into four or six, so that I can add additional power amplifiers and more speakers? Specifically, I want to route two channels out to my back yard, and add two more channels to my living room, for a total of four inside, two out. I need to be able to switch each pair on independently. That's why I want to get three amps.

These are separates, guys. The only way to go. Thanks!

Answer 1

You can use Y-cable splitters, but you will get 1 or 2 dBs of signal loss each time you split the signal. This would be defeating the whole purpose of surround sound however.

Either invest in a pair of really good loudspeakers, or get a 5.1, 6.1, or 7.1 channel preamp to run multiple amplifiers.

Because most outputs on solid-state consumer electronic components are of fairly low impedance and provide sufficient/standard drive... simply use one of those radio shack 'y" connectors - Male RCA to double Female RCA. The only real concern would be the "amount" of cable (capacitance) that you would be connecting; use short cables to minimize. This should work for your two-channel preamp but I'm surprised that it doesn't aleady have two outputs. You can also use the tape output if it is not in use as a 2nd or 3rd (by 2). Of course, if your preamp uses tubes this method is not recommended.

Answer 3

the amps you buy may have ins AND outs ,so you can cascade the # of outputs to 3 amps..If not, get an AV-61(i think Channel Plus) and take your audio out to the IN of this piece, then 2-3 outputs to the 2-3 amps..The av-61 is a powered part, so no loss involved...Also can do video out to multiple monitors as well..check ebay for av-61....of course there are similar, like answer#1, but model #'s always help you!!!

Answer 4

A gramophone record (also phonograph record, or simply record) is an analogue sound recording medium consisting of a flat disc with an inscribed modulated spiral groove starting near the periphery and ending near the center of the disc. Gramophone records were the primary technology used for personal music reproduction for most of the 20th century. They replaced the phonograph cylinder in the 1900s, and although they were supplanted in popularity in the late 1980s by digital media, they have since become the medium of choice for many music afficionados, especially in the electronica genre.

The terms LP record (LP, 33, or 33-1/3 rpm record), EP, 16-2/3 rpm record (16), 45 rpm record (45), and 78 rpm record (78) each refer to specific types of gramophone records. Except for the LP and EP (which are contractions of Long Play and Extended Play respectively), these type designations refer to their rotational speeds in revolutions per minute (RPM). LPs, 45s, and 16s are usually made of polyvinyl chloride (PVC), and hence may be referred to as vinyl records or simply vinyl. ::

You can use an "ACN" audio combined network box which can give you several isolated out for one input. Using an ACN instead of a "Mult" stops cancellations and Loading. Use two for 2 channel sound. My Home theater sound off Sat. HDMI has 8 channels, what up with "only 2" ??
