Universal Power Amplifier With Versatile Applications!

The McGrey PA-350BT is a compact Bluetooth power amplifier with an integrated USB/MP3 player that delivers serious musical power. Whether as a hi-fi amp for the party basement or to support vocal-focused events like karaoke nights or weddings, the PA-350BT amp more than meets every sonic demand.

Wide Range Of Formats And Connections

For maximum connectivity, a USB port sits on the front panel next to the integrated Bluetooth interface. As an additional connection option the PA-350BT offers a line input in cinch (phono) format on the rear. Communication with peripheral devices such as CD players, tape decks, MP3 players, mobile phones and tablets therefore works without any problems.

Karaoke Function

The compact Bluetooth amplifier is also ideal for karaoke parties. On the front panel you can connect up to two microphones (6.3 mm jack) simultaneously. Their levels are adjustable independently from the music. To give the voice the right expression, the microphone section also features an echo (reverb) function and a 2-band tone control.

Integrated Media Player

Operating the amplifier is made very easy not only by the illuminated volume controls: Six buttons and a highly legible display are provided for controlling Bluetooth devices or music files on a USB stick.

Extensive Menu For USB Playback

Once a USB storage device is inserted in the port, use the "Folder" button to access a menu where you can choose playback mode, one of six EQ presets or select a specific folder for playback.

Robust And Compact

The compact powerhouse with its rugged metal housing is perfect not only for permanent installation in the party basement or clubhouse, but also ideal for mobile use on the road. A built-in fan ensures the amp always keeps a cool head.

Compact and Powerful!

Someone writes that the part is made of plastic.
Not true, the housing is made entirely of metal, including the front panel and the inner chassis.
I can find absolutely nothing negative.
A lot of power for such a small box.
I can't measure whether it's really 100W into 4 ohms, but it's really loud into my speakers (with 8 ohms)!
I'm thrilled with this thing, a real recommendation to buy!

Despite the fact that the device is 90% plastic, the thing goes full off. I retired my old Sony amplifier, because now my sound system works great. Advantage of the plastic dream, it weighs nothing and still goes off. Disadvantage, you can only connect one device (CD player....). Nevertheless, gladly again.
Fully satisfied

Have purchased and tested the above PA system. I operate it in conjunction with a keyboard and 2 small satellites and stereo bass box.
The system works flawlessly and for the small price. I am a little surprised.
Small, light and good sound.
Would buy it again.

Question by Bianca D on 20.01.2022

Hello dear ones, is there any way to connect the PA-350BT power amp to the TV with a cable? TV does not have bluetooth. Need it to call up songs with lyrics on Youtube for karaoke night :-) if it is possible! Which cable do I need then? Thank you very much for your help ;-) have fun and stay healthy :-) greets Bianca

Answer by Musikhaus Kirstein:

There is an audio input (RCA/chinch socket) at the back for separate sources. Theoretically, your TV should also have something like this. Please have a look at what outputs it has. I'll be happy to check when I have the manufacturer and exact type of TV.

Here the link f. Chinchkabel:

In case of need, a headphone output would also work:

Question by Fabian on 11.08.2021

Hello
Can anyone tell me if you can connect to this amplifier also 4 boxes
Although actually only 2 inputs are on the back?

Answer by Musikhaus Kirstein:

No, the connection of 4 speakers is not possible in this case.

Question by Gosi on 04.12.2020

How can speakers be connected? Only via a normal speaker cable that is clamped on the back or also via banana plugs? Or is there another connection possibility?

Answer by Musikhaus Kirstein:

The connector can be used equally as a speaker terminal and as a jack for banana plugs.

Question by Christian Baur on 30.07.2020

Hello,
can I connect two 4 ohm speakers to this device?

Answer by Musikhaus Kirstein:

Boxes go from 4-16 ohms per side.

Question by Patrick on 20.09.2019

Can you also connect the power amplifier with the PC

Answer by Musikhaus Kirstein:

The power amplifier can be connected to a PC via an appropriate cable (e.g. https://www.kirstein.de/Live-Studio/Kabel-Multicores/Y-Kabel/Pronomic-ANE20-1-5JC-Audio-Noise-Eliminator-Kabel-Klinke-Cinch.html). However, only analog, the USB interface is only used for playback via a USB stick.

Question by Bernd Gaebler on 18.03.2019

Hello,

are the Treble and Bass controls only active in microphone mode, or are they general tone controls?

Thanks

Answer by Musikhaus Kirstein:

These controls only regulate the microphone input.

Question by robby on 16.03.2019

how to connect devices with the PA-350BT via Bluetooth. Unfortunately, there is nothing in the description. And on your page you also find nothing about it. Hope for a quick answer.

thanks a lot

Answer by Musikhaus Kirstein:

First, please press the "Mode"button until the small LCD screen says "Bluetooth". Then search for the power amplifier with your device and connect the devices.
