Sherbourn 7/2100 Amplifier - This is in like new condition.
This is one great amp. I used it as a back-up HT amp, but the wife
says all unused stereo equipment must go.
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.
