MTP41S

Breitband-Taschensender

MTP41S ist ein extrem kleiner und leichter Taschensender für professionelle Mikrofonanwendungen. Dank des OLED Displays, den Knöpfen für Schnellzugriff und dem Joggle Rad ist er sehr einfach und schnell zubedienen. MTP41S besitzt auch die neueste Wisycom HF Technik und ist so noch besser geschützt vor Intermodulationen und Rauschen.

Verbesserte Eigenschaften:
– Integrierter HW limiter

Eigenschaften

Bis zu 232 MHz Schaltbandbreite im Bereich 470–798MHz (andere Bereiche auf Nachfrage)
Innendesign mit flexiblem Schaltungsplatinen spart anfällige Steckverbindungen und macht das Gerät noch zuverlässiger.
Erweiterter Dynamikbereich mit HW Limiter im Eingang (30dB über Peak)
Ultraleichte Metall-Legierung (80g ohne Batterien)
Vom Benutzer wählbare Kompandersysteme
ENR (optimiert auf Rauscharmut)
ENC (optimiert für Sprache)
Batterie: 1x AA Alkaline, NiMH oder Lithium Akkus.
Laufzeit:
> 5h bei 50mW Ausgangsleistung
> 7h bei 10mW Ausgangsleistung
Infrarot Interface zur Fernbedienung und Firmware Updates
Einfache und schnelle Programmierung durch OLED Display, Direktwahl von Gain- und Frequenz sowie Joggle Rad.
Erweiterer Regelung des Mikrofoneingangs 80dB in 1dB Schritten.
Maximale Eingangsspannung: 26dBu (15.5V Clipping) für direkten Anschluss an Mischpulten oder Instrumenten.

Version: v1.30.0F

Date: 2015-07-06

MTP41S

fix – change power up/down delay: increase the delay of RF power up/down from 300ms to 500ms

Firmware

Version: v1.30.0P

Date: 2016-12-15

MTP41S

changed – disabled the editing by menu of audio AF input between dB (AF Gain) and dBu (AF Max Level). It is not possible anymore change the AF input between dB and dBu using the menu of the display. It is possible to change it only using the manager.

Firmware

Version: v1.30.0N

Date: 2016-11-16

MTP41S

add – management 5kHz step: the firmware is able to work at 5KHz of step (instead of 25kHz).

NOTE: to work at 5kHz step, the transmitter has to be pre-configured in the factory.
NOTE: Wisycom doesn’t suggest to upgrade the firmware on devices at 25kHz (standard version) because no new feature is implemented.
