OverviewThe LV1100 is an audio signal-processing Bi-CMOS LSIthat integrates input and output filters, a delay line (built-in memory), and a delay/reverb function with a maximumdelay of 120 ms on a single chip. It also provides built-infixed matrix (L+R, L–R) and front mixing (with level andphase switching) functions. A full complement ofsurround modes can be easily implemented by combiningthese functions.Functions and Features•Input switching (L+R, L–R, IN–A)•On-chip memory (12K SRAM)•Front adder (+3 dB, 0 dB, –3 dB, -∞)•Input and output filters•Input filter –7 kHz low-pass filter•Output filter –5 kHz low-pass filter: switchable with a 3 kHz low-pass filter•On-chip VDDcircuit•Input and output muting function•A simulated surround system can be easily implementedwith only one chip.•ADM A/D and D/A converters•Variable delay times– Short mode; Maximum delay: 60 ms. Delay timeselectable from six delay times in 10-ms steps.– Long mode; Maximum delay: 120 ms. Delay timeselectable from six delay times in 20-ms steps.Package Dimensionsunit: mm3067-DIP24SBi-CMOS LSIOrdering number : EN5506

An ISO 9001 CompanyModel MS-2, MS-2HThe MS-2 manual fire alarm stations aredual action devices. These stations re-quire that the outer door be lifted to ex-pose the actuation door which is thenpulled forward to operate the alarm toggleswitch. The actuation door is now lockedin the readily observable “alarm” position.To reset the station, a key (common toFCI control panels) must be inserted andturned ¼ turn clockwise, opening thestation. Closing the station resets theswitch automatically.An optional breakglass rod is availablefor positive indication of station operation.Model MS-2L (Institutional)Operation of the Model MS-2L institu-tional station requires that a special keybe used to release the actuation doorbefore it can be operated.Model MS-2-D (Multiple Contact)The MS-2-D features a DPST switch formultiple signaling via wire lead connec-tions.Model MS-6 (Single Action)The MS-6 station is a single action de-vice, requiring only the pulling of the ac-tion door to release the compressed but-ton switch. It is available either with ter-minals (MS-6T) or wire leads (MS-6).The station resets in the samemanner as the MS-2. The reset key iscommon to FCI control panels.MS-2
