20W STEREO AUDIO AMP THAT
FITS FLUSH TO THE WALL!
Overview
The Keene K-LAB-20 is ideal for use in multi-room
audio installations. It is a high quality stereo audio
amplifier that’s built into a std sized UK double pattress.
It provides 20W (RMS per channel) of amplification
eliminating the need to make space for a conventional
amplifier. It draws it’s own power from an externally
located mains adaptor and control is by infra red
remote.
Installation
Installation should only be carried out by a qualified installer or electrician, as a certain amount of
electrical knowledge is assumed.
1 Cut a hole in the wall large enough to mount the amp, (35mm depth) and cut channels or use
conduit for the cables.
2.The amp is mounted with the LED window downwards.
3. Remove the faceplate from the amp.
4. Holes are provided in the pcb to allow use of the original pattress mounting slots use 2 screws into
the slots to fix the amp to the wall. If fixing in a studded wall you will need to attach the supplied
metal lugs for plasterboard fixing.
5. Feed the speaker cables through the 2 top holes, the signal cables through the lower right hole
and the power supply connector through the lower left hole. Note power supply is 10 to 15 V DC
centre positive and must be capable of at least 2.5A if you are not using the recommended psu
please verify that the supply is correct BEFORE connecting it to the amp. If using the recommended
supply we suggest that it is connected in accordance with the instructions in section 9 below. The
amp can be used from a car battery or for that matter a car with engine running but NOT directly from
a car battery charger as these can damage the unit
6. In order to make a reliable and safe connection without short circuits it is recommended that the
speaker cables and signal cables are prepared and tinned prior to connection, with no more than ¼”
or about 7mm of tinned wire extending out of the insulation.
7. Connect the speakers being careful to keep both left and right connections the same. As the amp
is fully bridged there is NOT a common ground or return connection so if the positive speaker
connection for the left speaker is connected to terminal “A”, the same should be connected on the
right speaker. It should be noted that the recommended minimum speaker impedance is 4 ohms on
each channel, if driving 2 speakers or more on each channel use them in series if they are both 4
ohms or parallel if they are both 8 ohms. Note the speaker corresponding to the left input is actually
on the right hand terminals in the amp as viewed from the front.
