SKU: OSD-AMP300
OSD AMP3002-Channel 350W Per Channel, High Current Class A/B Stereo Amplifier Toroidal Transformers
A heavy-duty 350-Watt A/B two-channel dual source amplifier for use as a remote or single amplifier.
Dual Source Switching
The AMP300 also includes dual source switching to connect two audio sources and toggle between them for greater listening flexibility. Automatic source switching switches between connected sources with a priority signal-sensing feature, so if a DVD player is connected to input 2, then you decide to stream a movie through a game console, when the console is turned on, the AMP300 automatically switches to that source. The AMP300 also includes a variable delay control that lets you adjust the amount of time needed to "listen" for a signal from your main input, between 3 and 15 seconds. This prevents gaps between music tracks from accidentally switching your inputs. This high power amplifier includes two RCA signal level inputs so with the addition of an RCA-to-mini stereo cable (sold separately), you can connect your smartphone or other device.
Plenty of Power for the Price
Pair our AMP300 with the power-hungry speakers, and the sound quality will transform your listening experience. Rated at 350 Watts per channel peak power (470 Watts Bridged Mono into 8 ohms), the AMP300 can be configured as bridged or stereo. In bridged mode, you can combine the left and right channels into one audio channel which bumps up the power to a whopping 470 Watts (8 ohms). When playing dual sources, switch to stereo mode which reduces the power to 350 Watts per channel. It is the only high current 2 ohm load stable amp in the market.
Features
The AMP 300 also includes two sets of speaker outputs with front panel controls, auto-on signal sensing or 12-volt trigger, rear panel master level controls, dual line-level inputs with priority override switching and dual voltage of 110V/220V and auto signal sensing. This amp has a clean, brushed metal front panel with a volume control, power on and off button and a balance control knob to adjust the balance between the left and right channels and dial in just the right sound level mix. Special protection circuitry safeguards the amp from a short circuit.

If am using this Amplifier to run 6each either your 525 or 625 outdoor speakers, would this be able to handle all in parallel series mode without loosing any high definition nor the low end below "80hz" or do i need some kind 70v? I would prefer higher gauge than losing any definition on both high and low if need be. Am liking the spec on these 525 and 625. Possible speaker placement on concrete/medal siding, 15ft between speakers across and about 15ft to 20ft height. prefer stereo mode. Could this do the job?

Hi en76:
The AMP300 was created just for your application. It is a High Current Amplifier that will handle down to a 2 ohm load. It features a Large Powerful Toroidal Power Supply, lots of internal capacitance, Triple Darlington Audio Section, all discrete components and ample internal Heat sink. The three pair of AP650 will actual create a 2.7 ohm load to the AMP300. Which will increase the current draw and output. The AP650 are have a frequency response 37Hz to 22kHz. You will not lose any high or low frequencies. One of the advantages of 70V is you can use smaller gauge wire for longer distances. But that is contingent on cutting out frequencies below 100Hz. This is a true audiophile Amplifier with great sound quality. I would normally recommend 10 to 12 feet apart but since you have them higher than normal that will work. The AP650 is our best selling patio speaker.
Great choice on the amp and speakers.

ok got the amp but something is wrong cause when i pan the balance fully to one side, the speakers sound louder and full. When i balance it, volume went down and sounded as if its on different polarity. Double check so many times even change my wires, increase the gauge still don't sound right. Maybe factory error on wires with the balance knob. I can see the VU meter degreases when balance knob in the middle yet louder when i turn fully either left or right. something seems to be canceling each other on with balance knob. plus a crew fell out from amp.
Michael • 12/17/2019, 2:17:43 PM
I have 6 zones of speakers. Two speakers per zone wired in parallel. In each zone, the speaker wire runs through a wall plate along with a CAT6 cable down to the basement.
Speakers information:
Frequency Response: 40Hz-20kHz
Impedance: 8 Ohms
Sensitivity: 90dB 1W/1M
Power Handling: 100 Watts
I need an option to power all of this and control. This will be for background music.
Thank you.

Hi Michael:
You did not mention Volume Controls. So I am assuming you have no impedance protection for 6 pairs of speakers wired in parallel to 6 additional pairs, as you noted two pairs per zone through wall plates. Are the speakers wired parallel at the wall plate so you only have a single four conductor cable coming back to your central location? Or do you have have 12 four conductor cables coming back to the central location through the wall plates? So if no Impedance Matching Volume Controls you will need a speaker selector like our TSM series which has Internal Autoformers handling Impedance protection. If you only have 6 four conductor cables coming back then we would recommend using the TSM8 and connecting 6 of the eight zones. The protection is selectable: 1, 2, 3-4, 5, 6 & 7-8. You would use 6 or even 7-8. Especially if you are using the AMP300 which is perfect for your application. If you have all 12 pairs home run back to the central location then would recommend going with the TSM12 and connecting all 12 zones (2 sub zones for each of 6 main zones). The TSM 12 has selectable protection as well. 1, 2, 3-4, 5-8, 9 & 10-12. The AMP300 has no problem operating to a 4 ohm load. So let me know if that covers all your bases...
Note: Hi Michael: I have read your question again and it appears you maybe running just a single pair of speakers in in each zone. If no volume controls then I still think the TSM8 would be your best choice because of the internal protection. If you have volume controls handling your impedance Matching I would suggest the DSM6 (with selectable dual source per zone).

Hi Jim:
The fine print should say free shipping to the domestic 48 US states. Canada adds additional tariffs and freight charges. Checkout purchasing from AMAZON Canada and see what they charge.
