Amp model no. 2195 100 W Lead & Bass!!


I have recently been given the above amp and before I connect it to a speaker and switch it on I am concerned to know the correct protocol for connecting a speaker cabinet(s).  The speaker output sockets have no information directly next to them but a label elsewhere on the rear of the amp states "WARNING. Not to be used with speaker cabinets of less than 4 ohms"

My queries are:-

1. Is it safe (i.e. without risk of damage to the amp) to use just one speaker output as long as it is connected to a speaker cabinet of 4 ohms minimum impedance and appropriate wattage?

2. When using both speaker outputs can they both be connected to cabinets each of 4 ohms minimum impedance or are the outputs paralleled in which case would I need to work with two cabinets each of 8 ohms to arrive at a 4 ohms minimum impedance in total?

Apologies if the answer to this seems obvious but I have a little knowledge of these matters and while a little knowledge can be 'a dangerous thing' it can also lead you to be concerned (possibly unnecessarily) about getting things right!

Thanks in anticipation

Hello Jaison,

Regarding your question, the speaker outputs are in parallel with a minmium overall impedance of 4 ohms, this means you can connect 1 or 2 speaker cabinets if you are using two the minium impedance of both of them cannot be less then 4 ohms. For instance two 8ohms cabinets will give you 4ohms.


Kind Regards
