I have the Epson Moviemate Projector that I want to use the Passport 150 with for more sound at outdoor movies. I am getting no sound at all on the speakers. I am connecting the red and white plugs into the back of the epson projector (L/R Audio) and then plugging the jack to the passport pro where it says speaker. Still no sound on the speakers but I can hear the dvd on the projector... HELP!

Hi,

The Jacks on the rear of the Passport 150 Pro which say "Speaker" are the outputs. If you are trying to amplify the sound from your projector through the 150 Pro, you would go from the audio outputs of your projector to one of the inputs to the 150 Pro (1/8" jack labeled "Stereo" on channels 3 & 4, or the Left & Right input jacks on channels 3 & 4) in order to get the sound coming from the projector to be amplified through the 150 Pro.

Since there was confusion about what ports are for, might as well finish the description. The cables that come with the Passport with 1/4" plugs at both ends are for connecting the ports labeled "speaker" to the speakers. The one marked "Left" is for whichever speaker is placed toward the left of the audience. The one marked "right" is for whichever speaker is placed to the right of the audience.

It sounds like the projector has 1/4" outputs, so you'll need to provide your own cables to connect the projector to the Passport. Those should not be speaker cables. They should be "instrument" cables, made for line-level signals. You can get these at most music stores. These are the same cables people use to connect electric guitars to their amplifiers. Just get two that match.

While the external parts of speaker and instrument cables look a lot alike, internally, the wires are very different. Instrument cables are for line level signals and do a bad job when used as a speaker cable, and speaker cables are for speaker-level signals and they do a bad job of handling line level signals. You might not notice, but this is important.

Plug the one from the right output of the projector into the right input on stereo channel 3. Plug the left output of the projector into the left input on stereo channel 3.

If you prefer, you could plug both into channel 4 instead. Do no plug them into channels 1 and 2. Those are mono channels and will make all the sound come out of both speakers equally. To preserve the stereo sound, just use the two inputs on channel 3, or the 2 inputs of channel 4.

That should be all you have to connect, except of course, AC power to both the Passport and the projector.

Projectors usually come with fixed resolutions, meaning regardless of the quality of the signal they receive, they can only output in one resolution. Here's an example: a XGA (1024 x 768) projector that receives an HD (1920 x 1080) signal must shrink the information so it outputs in the 1024 x 768 format.

I'm having the same issue.

While the cable that runs from the projector to the Passport has two jacks (red and white) on the output from the projector, the other end only has one jack (green) that goes into the Passport.

Please advise.

Looking at page 7 of the Owner's Manual, Channels 1 and 2 take only mono input sound sources, using either XLR or 1/4" TS (Tip, Sleeve) cables. Channels 3 and 4 can take stereo inputs from either a single stereo 1/8" TRS (Tip, Ring, Sleeve) plug, or a pair of mono 1/4" TS plugs.

I'm guessing that your projector uses RCA plugs for the red and white connectors. The plugs look like a short metal tube with a thick wire in the middle that is concentric with the tube. Each of these two connectors are "mono" with two wires. One is the "hot" or "signal" wire. The other is the ground wire. When those two come together on the adapter cable, the ground wires are joined to make a "common ground" and result in three wires at the green end of the adapter.

I'm guessing that the green end has a stereo TRS plug (Tip, ring, sleeve). I don't know if this is a 1/4" plug or an 1/8" plug. If it is a 1/8" plug and fits in the single top port of channel 3 or 4 (the smaller port above the two larger ports), then great. This adapter works fine.

If the green end is 1/4", then it's not going to work for the Passport. It may physically fit into a 1/4" jack, but you are plugging a 3-wire stereo plug into a 2-wire mono port. This is not good. One of your two hot circuits gets shorted to common ground.

In that case, you'd be better off with getting two separate cables that go from the two projector outputs to the two 1/4" inputs for channel 3 or channel 4. The projector's "Left" plugs to the Passport's "Left" and the projector's "Right" plugs to the Passport's "Right".

I hope this helps.
