.0 Total System Approach
Adamson Systems Engineering has long been using
Lab.gruppen amplifiers and XTA processors to power
and process SpekTrix Systems. All of our processor
settings such as gain structure, equalization, time and
phase alignment have been derived from extensive
testing using this specific equipment combination. The
use of this equipment evolved into a complete system
solution, adapted by Adamson partners around the
world.
Recently Adamson has added LAKE processing as a
supported solution, with a complete settings library
available by request and on-line.
We recognize the benefits of completely scaleable
system that can also use multiple elements from
Amplifier/Speaker load balancing.
To create a balanced amplifier load format common
to all SpekTrix systems, Adamson Systems Engineering
designed a specific driver compliment.
Each SpekTrix:
1)
One 8 Ohm low frequency driver on pin 2 +/-
2) One 8 Ohm midrange driver on pin +/-
) One 8 Ohm high frequency driver on pin 4+/-
Setting up processors and amplifiers
Processor settings, available for download on our website, are set in conjunction with the appropriate settings
on the amplifier, normally set at 29dB or 2 dB of gain. Please assure that these settings are correct and
correspond with the processor settings when configuring your set-up.
NOTE: Use only factory recommended equipment and settings. If you are using
amplifiers and/or processing other than our example, please consult the manufacturers
specification and instruction manual to assure that gain structures, limiting, equalization
and connections are set up in accordance to our speaker specification. Failure to do so
will result in inaccurate performance and risk of irreversible and /or personal damage,
and thereby voiding warranty.
For Lab.gruppen, to link inputs and set the amplifier gain, the manufacturer provided an 8-switch dipswitch
on the back of the amps. The center switches should be in the “up” position. and the gain should be set to
the appropriate combination on switch 1,2, for channel B, and 6,7,and 8 for channel A. The example is set
at 29dB. Link parallels input A to input B. To unlink amplifier channels A and B, move the two center switches,
4 and 5, to the down position. This will allow the user to have separate inputs to channel A and B of the
amplifier.
