The OSD Audio PA150 commercial integrated Pre AMP/ 120 Watt power amplifier is the ideal control center for restaurants, meeting halls, schools or other small, commercial venues where multiple microphones and line audio sources are needed. This versatile, powerful and affordable commercial amp features 3 XLR microphone inputs and 3 signal-level inputs, plus front-mounted gain control knobs, master bass, and treble. The MIC 1 Input has priority over the other inputs. When the MIC 1 Input signal is present, the PA150 will automatically mute other inputs and only MIC 1 Input is available to output. . An upgrade typically found on more expensive commercial amps, the PA150 also features chime and alarm buttons. The chime button temporally mutes the system when pressed, while the alarm mutes the system and rings until the button is released. The PA150's XLR microphone inputs and signal level inputs can be connected to sources like CD players, TV outputs, Smartphones, MP3 players, and the unit even includes a telephone input. The amp's output options (70 Volt, 100 Volt or 8-ohm mono) can also be set up to power 5 to 10 speaker 70V systems.

What's on your mind?

Sunday • 12/17/2019, 2:17:43 PM Is this a 120W RMS amp or just normal120W?
Customer Service • 12/17/2019, 2:17:43 PM
HI Sunday: This AMP is a true 120 watts RMS double the power of our PA-90 and half the power rating of our other new PA Integrated/Mixer Amplifier the PA-270 (240 W). All three units share the same chassis size but increase the size of the Power Supply and number of internal components. TS-2274
Matt • 12/17/2019, 2:17:43 PM What is the best source of music to imput into this amp? And where is the best place to buy a mic?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Matt, You can really input any source that uses RCA. You can run something like an iPod, computer, CD player, receiver, etc. We don't do Pro Audio, but I'm sure an Amazon or Google Shopping search should give you good results for where to find an affordable mic. Thanks! -Bm 2371
Kevin Hoyland • 12/17/2019, 2:17:43 PM Can I drive more than 10 speakers ?
Customer Service • 12/17/2019, 2:17:43 PM
Purely depends on the wattage each speaker is set to. 10 speakers set at a max of 12 watts would use up the full 120 watts.
Lou • 12/17/2019, 2:17:43 PM How do you connect a smart phone to this device to play music
Customer Service • 12/17/2019, 2:17:43 PM
Hi Lou: You would need to do it the old fashion way using a 3.5mm to dual RCA adaptor cable. The 3.5mm would connect to your Headphone Jack of your phone and the RCA's would connect to one of the Aux inputs (Right and Left female RCA). TL/4143
Jim Crowe • 12/17/2019, 2:17:43 PM how do you switch between AUX inputs? I don't see a select switch on front.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jim: This is a Pre amp mixer so all three aux inputs are active and controlled by the volume knob for each Aux 1, Aux 2 and Aux 3. Same with the three mic inputs as well. The difference is the Mic 1 mutes the other 5 inputs when activated. Of course none are active unless something is connected to each and turned on. We also have a Pre One Pre amp that has switchable inputs and a single Mic mixer that mixes with whatever source you select but is 4/8 ohm only no 70V. I hope that helps, checkout the owners manual for more in depth descriptions. TL/4342
