UNPACKING AND INSPECTION 

Before accepting the Model V610 “COMPLIMITER” from the shipper, inspect the shipping carton for external 
damage. Any sign of external damage must be noted by both customer and shipper, and should be called to the 
attention of the insurance investigator. After the equipment is unpacked, inspect the unit for any damage in 
shipping. Check for scratches or dents, damaged knobs, or connectors. If damage is noted, do not use the unit 
unless instructed by the insuring agency. 

NOTICE 

The Spectra Sonics Model V610 contains no user serviceable parts. Removal of top or bottom cover 
plates shall void product warranty. See warranty section for additional warranty information, page 20. 

INTRODUCTION 

The Model V610 “COMPLIMITER” is a compressor/limiter system with performance both measurably and 
audibly discernable as “beyond the state of the art”. Because of extremely low noise characteristics of the 
design, the system has a very low input level threshold of -40 dBu, thus providing the greatest input sensitivity 
and compatibility with the widest range of system levels available on the professional audio market. Depending 
on the program content, the Model V610 “COMPLIMITER” will accept an input signal from -50 dBu to  
-40 dBu just prior to beginning compression, as well as standard line level input signal.
Control functions are provided on the front panel for input level threshold, continuously variable compression
slope (ratio), release time, power, and output level. Visual LED indicators for peak limiting and system
overload are provided, in addition to Vu and LED gain reduction meter monitoring. This manual, as well as the
quick start guide is provided to aid the operator in obtaining maximum performance from the Model V610
“COMPLIMITER”. READ THE INSTRUCTION MANUAL, especially the QUICK START GUIDE, before
using the unit.
