AcoustaBar Power Supply DC18V 4Amp Smaller Positive Pole

• For AcoustaBar SD-400 some 2011 models
• Universal 120/ 240v AC, 50/60 Hz
• US 3 Prong AC Plug
• Output: 18V DC, 4Amp
• 5.5mm OD, 2.1mm ID DC output Plug
• Fits smaller positive pole(pin) at DC input socket on AcoustaBar SD-400 unit*

* From the rear of the unit, there is a color dot sticker near Power Button at right side of the Amp to identify such unit. These units usually are equipped with 2.1mm OD positive input pin on the center of the DC-IN socket. Even though PS-18V4A power adaptor will probably work with these SD-400 sound bars, but, it is more appropriate to use WR-18 to get proper contact of the smaller positive input pin.
