Sherbourn 7/2100 Power Amp Good Working Condition

Not original owner. Lightly used (only four of the seven channels) to drive a couple of pairs of speakers. This is an absolute beast of an amp, 115 pounds. All 7 channels tested, working. 

Local pickup available, if you want to save the considerable shipping cost. Shipping, we'll use UPS double box and insure

From Hometheaterhifi:

The Sherbourn 7/2100 amplifier is a heavyweight monster (100 
pounds). It packs seven monoblock amplifiers capable of delivering 200 W each 
into an 8 ohm load (300 W into 4 ohm) in a single chassis. Some people use the 
raw measure that the heavier the amplifier, the better. If you are from that 
school of thought, then you will be very happy with this amplifier.The 7/2100 
amplifier uses two power chords, which should be connected to two different 
electrical outlets. This is because the 7/2100 may draw more current than a 
single outlet could provide (a typical outlet could handle up to 15 A of 
electric current), especially when it is used to drive low impedance speakers. 
In my opinion, this is a more elegant solution than requiring one to install a 
dedicated 20 A outlet, as some high-current amplifiers from some other 
manufacturers require.The 7/2100 amplifier can accept balanced or unbalanced 
inputs. High quality five-way binding posts are used for the output terminals. 
All the input and output connectors are gold plated and seem to be very robust, 
so I have nothing but praise for the build quality of this amplifier. . .

 

One of the nice features of the 7/2100 amplifier is that it 
is bridgeable. Three pairs of the input channels on the back are separately 
grouped, and a bridging switch is provided for each group. Each bridged pair 
can produce up to 400 W into 8 ohms. With the bridge capability, you can 
configure this seven-channel amplifier into a six-, five-, or four-channel one 
depending on your need.Another nice feature of the 7/2100 amplifier is the 
inclusion of the Load Detection System (LDS) switch for checking the 
correctness of the speaker connections. This switch can show the status of the 
speaker connection for each channel through a colored LED without needing an 
ohmmeter or a walk through. Green LED indicates a good speaker connection and 
correct speaker impedance, orange indicates an open circuit or high speaker 
impedance, and red indicates either a short circuit or a too-low speaker 
impedance. When the indicator shows orange or red for a channel, it is 
suggested that you check the speaker connection for that particular channel.Except 
for the power on/off button, a small blue LED indicator, and the Sherbourn 
logo, nothing else clutters the faceplate of the amplifier. This amplifier can 
be put in always-ON mode or remotely triggered in two ways: using automatic 
signal sensing or 12 V DC voltage. . . .

The 7/2100 is a great amplifier that I'm sure will 
complement many home theater systems nicely. This superb sounding amplifier has 
ample power to satisfy even the most power hungry system.
