GROUND LIFT SWITCH

Application of the ground lift switch.

In some cases, when devices with different grounding configurations are connected, a

distinctive hum might occur. It might be caused by a so called closing of the ground

loop in devices simultaneously connected to the power supply. In such cases it might

be helpful to disconnect the analog ground from the preamp grounding. Casing of the

device is still grounded, so normal use of the device is still safe. Only the analog

ground is disconnected, which prevents the creation of the ground loop.

In the „CHASSIS" setting the analog ground is connected to the grounding.

In the „FLOATING" setting the analog ground is disconnected from the grounding.

„REMOTE OUT" (TRIGGER) is used to remotely turn on an external device

simultaneously with turning on ASP-1000. In order to use this function the external

device, e.g. an amplifier, must be equipped with an appropriate input, thus enabling

turning it on remotely. At the moment of turning the preamp on, 12V DC voltage

appears at the „REMOTE OUT" socket. The maximum output current is 100mA.

The external device should be connected via a 3,5 mm mini-jack.

RECOMMENDATIONS TO ACHIEVE OPTIMAL SOUND

PERFORMANCE

Every ASP-1000 is rigorously tested by the manufacturer in terms of the highest

quality of manufacturing, as well as the consistency of all technical parameters.

In order to enjoy the best sound quality offered by ASP-1000 owner should always

follow the below listed guidelines:

•

All output and input connections should be made with high quality, shielded cables

- with connectors ensuring their firm mounting in the input/output sockets of the

ASP-1000 preamplifier.

Make sure that all the cables are properly connected.

•

It is not advised to apply exceedingly long unbalanced signal cables (RCA). When

the application of long cable is necessary, we recommend using balanced cables

(XLR).

•

It is recommended to check the correctness of all connections.

•

In case of trouble with humming in the loudspeakers, it is advised to disconnect the

analogue ground from the grounding with the „GROUND SWITCH"
