A Closer Look: Big Joe IV Mono Blocks
For those unfamiliar with mono blocks, they are separate mono amplifiers in which one amp is used for each speaker channel. Mono blocks are popular in the tube based crowds but they seem to be making a comeback for the solid state fans also.
These units are power amplifiers; they have no input or output level control and must be used with the Mass Preamp or other device that provides level control. Lets have a look at the Big Joe IVs.
Front
The front panels of the Big Joe IV follow very modern and clean design ideas. The lines are clean and you have a simple LED indicator for power. We can see the power ratings on the front to remind the end user of how much actual audio muscle they have in these small units.
Rear
The rear of the units is equally clean, offering simple mono RCA input and banana jack outputs for your speakers. There is also the master switch for the power supply with the DC power input right beside the switch.
Big Joe PSUs
The external PSU that are bundled with the BJ IVs are big and quite heavy duty in comparison to other power adapters we have seen for desktop amplifiers. The BJ IVs are running on 30VDC for each unit so that is a bit of power but considering the power they push out this seems reasonable.
