Introduction - LD Systems AM 8 Manual De Usuario

The warning triangle with lightning symbol indicates dangerous uninsulated voltage inside the unit, which may cause an
electrical shock.
The warning triangle with exclamation mark indicates important operating and maintenance instructions.
Warning! This symbol indicates a hot surface. Certain parts of the housing can become hot during operation. After use, wait for
a cool-down period of at least 10 minutes before handling or transporting the device.
Warning! This device is designed for use below 2000 metres in altitude.
Warning! This product is not intended for use in tropical climates.
To prevent possible hearing damage, avoid listening at high volume levels over long periods of time.
Even exposure to short bursts of loud noise can result in hearing loss. Please keep the volume constantly at a comfortable level.
CAUTION! HIGH VOLUMES IN AUDIO PRODUCTS!
This device is meant for professional use. Therefore, commercial use of this equipment is subject to the respectively applicable national
accident prevention rules and regulations. As a manufacturer, Adam Hall is obligated to notify you formally about the existence of potential
health risks.
Hearing damage due to high volume and prolonged exposure: When in use, this product is capable of producing high sound-pressure levels
(SPL) that can lead to irreversible hearing damage in performers, employees, and audience members. For this reason, avoid prolonged
exposure to volumes in excess of 90 dB.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

INTRODUCTION

The LD Systems AM 8 is an automatic 8 x 2 matrix mixer with balanced mic line inputs, 96 kHz/24 bit signal processing and a frequency
response of 20 Hz - 30 kHz. The Priority function of the AM8 automatic mixer can be switched on individually for each input; the total threshold
for channel activation is selected automatically or manually using the threshold controller. When the levels of input channels drop below a
certain threshold, these will be muted by the Automix feature. This means that for the transmission of a channel, background noise, feedback
and unwanted comb-filter effects from other active channels are effectively suppressed and the speech intelligibility is thus enhanced. When
the levels of input channels rise above a certain threshold, these will be automatically activated.
On the front panel, encoders with LED ring and peak value display for gain control in 1 dB increments, are used for selecting the input
sensitivity and priority. A Master encoder with two LED chains is used to adjust the output level, turning on output 1, 2, or both and to select
microphone or line level.
