This is the top heavy duty model that has independent fully isolated outlets for 4 amplifiers, one high level output for TV...and several outlets perfect for low power devices such as preamps.  Each outlet has independent circuit breakers, plus a toggle switch for selecting 3 choices of ground scheme. Comes with cam-lock heavy duty removable power cord.  Great condition. This unit is the size of a huge amplifier...it is black and very attractive. I will give you a huge discount on this due to the shipping weight...roughly 80 pounds. Unit cost over $1400.00 new. I will sacrifice at only $475 if payment is secured no later than 9/23/10....it goes into long term storage after that date...I will be leaving out of state...sale is not possible past that date. Buyer pays shipping and insurance.NO LONGER OFFERED
