At the Cache Creek Ridge Ride, we connected a Behringer: MICROAMP HA400. This allowed the net control station connect an external speaker and rwo pairs of headphones for net control and one for the logger. The volume of each device and be independently adjusted. The external speaker allowed the ride management and passer-by to hear what was going on, but the headphones allowed the operators to focus on their tasks. It work well. It also works well at home allowing the use of the external speaker, headphones, or both.
The MICROAMP HA400 available from Amazon.com for $19.99.
