All of the Bogen PA amplifiers have a reputation for incredible durability.   We routinely find them in installations for schools, houses of worship where they have been quietly providing reliable PA support for decades, despite often poor environmental conditions and neglect.

This particular unit is in Very Good condition, with all 6 mic inputs in working order.  

Here are some features and specifications from Bogen:

1. 6 low impedance transformer coupled mic inputs
2. Built in Phantom supply on the "B" versions of the CT60 and CT100
3. Two Aux inputs with an AUX1/2 fader knob for line level inputs
4. Built in mic precedence, remote volume control, 600 Ω line input and outputs
5. Detented EQ faders for feedback control, 10 total.
6. Compressor with front panel screwdriver control
7. Multiple speaker output configurations accept 8Ω, 25 volt and 70 volt lines.
