1. Power switch

Flip this switch to turn power on and off.

2. Power led

This led is lit when power is on.

3. Channel 1 – 8 level controllers

Set the ch. 1 to 8 channel level individually with these level controllers.

4. Channel 1 – 8 status leds:

Upper “limit” led lights up when the internal limiter is active.

This should not or only very sporadically happen. Turn the level controller down if this led lights up

frequently. Lower “signal/protect” led lights up green when a sufciently high signal is present at

channels 1 to 8.

This led lights up red when the internal protection circuitry is active, due to an overload or a short

circuit. When powering up the PA8250, these leds are red during a few seconds,

this is to avoid turn on plops and clicks.

The PA8250 incorporates eight independent high power ampliers in a convenient 19” enclosure.

For those who need more power, there is the possibility of bridging the channels.

This way you can congure the amplier to your needs with a push of a button.

1. Fuse

Replace only with a fuse of the same rating: 10 amps, slow blow.When this fuse blows often, please

contact your local dealer and have your device serviced.

2. Link switch

When pushed in, this switch allows you to link the inputs of the odd and even numbered channels

through. E.g. left input on channel 1, right input on channel 2, by pushing the 1to3/2to4 switch, the L

input on channel 1 is switched through to channel 3 and the R input on channel 2 is switched through

to channel 4.

3. Balanced inputs channel 1 to 8

Connect your balanced input sources on these Euroblock connectors.

4. Unbalanced inputs channel 1 to 8

Connect your unbalanced input sources on these cinch/RCA connectors.

Do not use balanced and unbalanced on the same channel !

5. Highpass lter switch

Push this switch to lter out unwanted rumble or low frequency sounds.

6. Stereo/mono switch

Push this switch for stereo or mono operation.

7. 2 channel/bridged switch

Push this switch to put the amplier in bridge mode: in this mode you can unite the power of two

ampliers into one more powerful amplier. In bridge mode, minimum load impedance is 8 !

Connect the speaker – terminal to the even numbered output channel’s + connector and

the speaker + terminal to the odd numbered output channel’s + terminal.
