Settings
a.
AC Voltage is automatically set for a range from 100V AC to 250V AC. There is nothing to set.
b.
Audio Input Mode Select. The Alpha is shipped in the following default mode: XLR/IP over Cat5 with
Analog backup. There is no need to change the input setting if you are going to use either of these
two inputs. If you want to use the AES over twisted pair into the XLR input, you can switch the input
mode by pressing the input button on the connector plate at the bottom of the speaker. Monitor
the status by looking at the XXX LEDs.
c.
EQ preset. The Alpha ships with a response curve that is voiced for the most typically neutral
voicing in-room. This is mostly flat anechoic response for both the axial and sound power frequency
response. This is stored into Preset 1. Preset 2 is the same as Preset 1 with 3dB more High
frequency energy. Preset 3 is the same as Preset 1 with 3dB less High frequency energy. You can
switch between the presets by pressing the preset button on the connector plate at the bottom of
the speaker.
d.
Input Volume. Set the volume knob to maximum gain.
e.
Input EQ. Set to ON.
f.
DSP programming. The Alpha speaker includes a DSP engine with more than 60 bands of response
tailoring, plus several other signal processing functions. These are programmed through a
computer application, and requires advanced control by a factor trained professional. Contact
Grimani Systems for DSP programming and system calibration services.
