MODULAR SIGNAL PROCESSING

Flex Series Modular Signal Processors

General Description

Ranes Flex Series of modular signal processors repre­sents a milestone in system flexibility, quality and cost­effectiveness. Unlike previous modular approaches, the Flex
Series requires no expensive mainframe in order to operate.
Each module is self-contained and interfaces directly with
other professional audio gear via 3-pin, screw terminals, ¼"
and DIN connectors. A multi-pin bus system on Flex mixer
modules reduces interconnect wiring to a single short DIN
cable (supplied), yet provides the kind of multiple program
capability found on large, expensive mixing consoles.

Each Flex module conforms to the industry standard HR
(Half Rack) mechanical specifications, allowing vertical or
horizontal, recessed or flush mounting into standard EIA
equipment racks. Vertical mounting is achieved via a low-cost
metal frame which holds 10 modules and occupies 6 rack
spaces (10.5"). All active modules are powered externally by
either the small RS 1, UL listed, CSA certified, IEC compat­ible power supply shipped with each unit, or by the vertical­mount FRS 8 Flex unit, or by the horizontal RAP 10 power
supply. This low voltage external power supply systemalso

being standardized by the pro audio industrysignificantly
improves signal quality, minimizes system grounding
problems, and qualifies all Flex modules for Class 2 operation
per the National Electrical Code. This means Flex systems
carry automatic agency acceptance (UL, CSA, ETL, etc.)
without the expensive approval process, allowing the timely
development of top quality equipment at more competitive
prices.

system can be custom tailored to its exact requirements,
without the wasted costs of buying more than you need. And
designed-in expandability means you can start with minimum
outlay and increase system capability as the need and budget
allow. This is particularly true when assembling a mixing
system with Flex. Any size 4-bus mixer can be assembled
with just the right number and type of inputs and equalization.
Even a small start-up system offers features such as two
separate source-selectable auxiliary buses, insert loops,
phantom power and much more. Superlative quality, perfor­mance and flexibility distinguish the Flex Series.

Flexibility is the key concept for the Flex Series. Each
