Question:
I have purchased 4 dual core speakers and 5 impedance matching volume controls. I have everything installed and the impedance matching set for 5 pairs of speakers since I will be adding one more. I have a Onkyo 607 receiver with zone two output. The output is either direct or Line out. I understand the output is for only one set of speakers. I tried to drive the other pairs, but the zone 2 faulted out. How can I drive the other speakers and still use the feature of different sources for the other rooms? Do I need a separate amplifier or a speaker distribution box.
Answer
Most receiver's 2nd zone is only rated for one pair of speakers, if you want drive more pairs of speakers (especially more than two pairs), we highly recommend using the separate amp (use line output from 2nd zone).
Question:
Hi, I have three rooms (bar, outside deck, and living room) I have a total of 6 speakers (2 per room) that i would like to hook up to a receiver/amp. I would also like to have the volume of the living room higher than bar/outside. I'm hoping that your product (AMP300 Dual Source, Four-Channel 300W High Definition Amplifer (MI6)) will be able to address all my concerns. Will this one work for me? Thank you in advance for your help.
Answer:
The Amp300 will have plenty power for your 6 speakers. If you want to control the volume of each room, installing a impedance matching volume control for each room will do the job for you.
Question:
I bought an amp300 amp about three weeks ago as part of your whole house audio kit. it is wired through the speaker volume controls knobs. Several times a night it will quit putting out sound. If I turn it off and on, it will work again for a while... and then do it again. It is only turned up to about 35 or 40% power. I am using the protection feature on the selector, I turned down the "master volume" on the back of the amp to only about 75% and it hasn't tripped since, do you think that would help or maybe just coincidence?
Answer:
Sending too much or too little power to the speakers will cause damage to them. The best way is turning your speaker selector impedance swith to "off" and use your volume controls to do the impedenece matching. In your case if you haven't experience any problem at 75% master volume, I would leave the setting at that.
Question:
Im intressed in bying "AMP300 duals source 300w highdefinition"
But i have some questions first.
1. Can you use A and B speaker at the same time?
2. Can you connect 8ohm and 4ohms speakers to this product?
3. Do you get a remotecontrol so you can change the volume in the different speaker zones?
4. Can you connect a subwoofer to a "AMP300"?
5. Can you connect a "ISS6 zone speaker selector" into "AMP300"?
6. And if so, do you connect it to the bridge output?
7. Iīm going to connect six speakers in "ISS6", two front speakers and one subwoofer in AMP 300 if thats possible?
8. Can you connect it to 220v wall socket (Swedish)?
9 Do you ship to Sweden?
Answer:
1. Yes it is dual output.
2. Yes you can - though recommend you use impedance matching volume controls.
3. No remote for this unit but we do sell ATM7 speaker selector with remote (7-zones)
4. Not recommend.
5. Yes you can connect to speaker selectors.
6. Not bridged output, the speaker selector have left and right input (stereo)
7. No the speaker connector is for speakers only, not subwoofers.
8. Yes the unit has dual voltage inputs (110-220V)
9. Yes we do ship to Sweden, in shopping cart, choose Int' USPS as shipping method.
Question:
I'm setting up a whole house system. In the living room I have an Onkyo TSX 603 x driving 5.1. I will be usung line out from Zone 2 on the back of the 603 to an amp. I want a total of 4 zones, 2 inside the kitchen/dining room, 1 on the back deck and 1 on the front porch. I have a Niles SS4 zone selector. The speakers are already installed in the ceiling for the kitchen/dining room. I think they are rated 10-100 w @ 8ohms. I want to use the volume controle on the amp for these 2 zones.
I haven't decided on the outdoor speakers yet, I will be usung volume controls for each outdoor zone.
My question is will the amp300 deliver enough power for the 4 zones? If I'm looking at it correctly the 300 watts gets devided by 8 (4 pairs) right? it comes out to 37.5 watts per channel. Is this enough power? Or should I use the 12 channel amp you have to bridge the outdoor sets?
Answer:
The amp300 should have enough power for your four zones, depends on the sensitivity of your speakers, normally you play 15 to 20W to your speakers, if you play 35 to 40W you are having a party.

Well, what can I say... I really enjoyed my experience with OSD. Not only did I place my order 4 days before Christmas, they actually emailed me, and spoke to me on the phone, over the holidays to ensure my product would be shipped in time.
I purchased a sizeable amplifier, and two nice speakers for our back deck... And the quality is simply great. The amp, is built more solid than my 1500$ Harmon Kardon receiver, with a 4mm thick aluminum front panel, and good quality caps/EMI shielding on the inside.
These guys were even a pleasure to deal with, as I live outside of the US, they called me (on their bill) to discuss ways to make the ~600$ shipping, MUCH cheaper. We ended up getting shipping down to 200$, for a 97lb order. I was very pleased... and would order from them again. - RSR
I purchased this amplifier to run a pair of the A830 outdoor speakers. I was leery about purchasing this amplifier because I couldn't really find a good review of it and it also has a noise rating of "less than 0.2% THD N" when I ordinarily never purchase an amplifier with a rating of anything above 0.0x% (x being a value of 1-9).
One thing I did find odd about the amp was that the "Master Level"? of both channels was turned all the way down to low, or off, thus making no sound come from the speakers when I started testing the amp. Once I noticed this setting I corrected it by turning both "Master Level"? channels up to the middle. This middle setting produced enough volume to make the A830 patio speaker loud enough that the neighbors were looking out of their windows. The A830 at this volume were clean, no distortion, and I couldnäó»t be more pleased with this amplifier. - rwinkdopey
I purchased the amplifier last august as part of my preparations for a home audio system during construction of our new house. The ceiling speakers were mounted then and i organised to purchase this amplifier at the same time.[...]I cannot recommend their pricing [...] highly enough. i've finally got the system set up and it sounds fantastic. The amp is driving 4 split sets of ceiling speakers in the house and managing this without any problem at all - in fact I've had to set the output way down! i've never been happier with a purchase than my recent experience with OSD - A380
