Kemo M031N 3.5 Watt Universal Mono Amplifier Module
Suitable to beef up game sound?
We love Electronic Catch Phrase which is modern version of Hot Potato. The game ticks faster & faster as you pass it from one player to another until it finally buzzes to signal the end of the round. The problem is the sound is just not loud enough for our party crowds. I'd like to epoxy a small amp to the back and hopefully use the same internal batteries (4.5v) and speaker. Any thoughts on whether this unit may help make simple mono ticking and buzzing LOUDER? Thanks!http://www.hasbro.com/games/en_US/shop/details.cfm?R=1545DB5F-19B9-F369-D9CE-95189BB5EF10:en_US
I suppose you could use this for an application like that, but you would need a potentiometer to adjust the volume level and this would likely drain the batteries pretty fast so it doesn't seem to practical.

What is the current draw, will it work off 9V battery
In other words, would this be better than messing with an LM386?I realize turning it up would use more power. But at low power...
Unfortunately the manufacturer does not specify the current draw of this amplifier however a 9V battery will not have a problem powering it.

How to control volume?
What size potentiometer do I need and should I use it to control the input signal from my iPod? or should I use it to control the power to the amplifier? I can control volume with my iPod, but will adding volume control to the amplifier give me better sound?
Most volume controls are placed between the preamp and the power amplifier. A 10k ohms potentiometer is a suitable value for most audio aplications. You will need to use a dual ganged pot for stereo. Good luck.
