Placement
The A22 amplifier is supplied with 4 mounting
brackets, which can be fixed to the sides of the
housing with the tab facing upwards to enable
the A22 to be mounted under a counter-top
The A22 can even be mount against a wall. ed
Alternatively, the A22 may be used free standing on any flat surface or 2 units can be
mounted side- -side in a rack with one mou ing bracket facing forwards at each sideby 19”nt ,
occupying a 1U rack space (the self- hesive feet wi need to be removed to allow this) 4 ad ll
Speaker connections
The A22 has 2 speaker output - CH and CH2 - on single removable screw terminal block, s 1 a
which can b red as Left and Right stereo outputs (13, 14) e wi .
Connect the negative screw terminal to the negative “–” “–” speaker terminal(s)
Connect the positive +“ ” screw terminal to the positive + “ ” speaker terminal(s)
Use speakers with a combined impedance no lower than 4 for each output channel. Ω
• If each speaker being connected 4 , then connect only 1 speaker to each channel. is Ω
• If each speaker is 8 , you can connect speaker 2 speakers in parallel per channel. Ω1 or
• Do not connect more speakers to either channel as this may cause damage to the A22. ,
An example of wiring 8 speakers the A22 is Ωto
shown opposite .
A single 8 speaker may be connected to a Ω
channel or 2 may be connected in parallel to
present a combined 4 load to the output. Ω
The impedance of the load measured in ,
“Ohms” (Ω), will also determine the power .
The amplifier delivers its maximum power
output at the minimum impedance rating (4Ω).
If the impedance is higher (e.g. 8 ), then the Ω
output from that channel will be lower.
The combined load on each output shares the
power from th amplifier channel at .
This means that if two 8 speakers are connected to a single output in parallel, they will each Ω
receive half of the full power. If the amplifier is delivering W to two 8 speakers connected 50 Ω
in parallel, they must each be able to handl 25W. e
