Placement
The A2 amplifier is supplied with 4 mounting 00
brackets, which can be fixed to the sides of the
housing with the tab facing upwards to enable
the A2 to be mounted under a counter-top 00
The A2 can even be mounted against a wall. 00
Alternatively, the A2 may be used free standing on any flat surface or 2 units can be 00
mounted side- -by side in a 19” rack with one mounting bracket facing forwards at each side,
occupying a 1U rack space (the 4 self-adhesive feet will need to be removed to allow this)
Speaker connections
The A2 has 2 speaker outputs - CH1 and CH2 - on a single removable screw terminal block, 00
which can be wired as Left and Right stereo outputs. (13, 14)
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 is 4 , then connect only 1 speaker to each channel. Ω
• If each speaker is 8 , you can connect 1 speaker or 2 speakers in parallel per channel. Ω
• Do not connect more speakers to either channel, as this may cause damage to the A2 00.
An example of wiring 8Ω speakers to the A200 is
shown opposite.
A single 8Ω speaker may be connected to a channel
or 2 may be connected in parallel to present a
combined 4Ω load to the output.
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. 8Ω), then the output from
that channel will be lower.
The combined load on each output shares the power from that amplifier channel.
This means that if two 8Ω speakers are connected to a single output in parallel, they will each
receive half of the full power. If the amplifier is delivering 50W to two 8Ω speakers connected
in parallel, they must each be able to handle 25W.
