Section 1: General Features and Specifications
The 1U ALM26 rear panels are comprised of modular panel sections. In any given ALM26 model, from one to three of the modular
panel sections contain the audio input connectors (unused sections have blank panels), with a fourth remaining section containing the
alarm controller features. This arrangement permits mixing of different types of input modules, although such mixes are considered
special order items. The number of channels is designated by a number following the ALM26 (i.e., ALM26-24 = twenty-four
channels).
The following illustration shows three types of input panel section modules (two digital and one analog) available for use in the ALM26
Series. Analog models are referred to with an "A" appended to the standard product name and Digital (AES) models are referred to with
a "D" appended. Models featuring Phoenix connector inputs do not append any letter to the model name as these connectors are
considered standard. BNC connector inputs append a "/B" to the model name and XLR connector inputs append an "/X". See page 5
for a list of all standard models in the ALM26 series.
Please note that XLR models are limited to twelve channels (or less) due to space constraints when using the larger XLR connectors.
