I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.

Clear and easy to read. All details as expected. Price acceptable , and quick delivery.
;
Quick response and exactly what I was looking for and at a great fair price!

5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.
Beiblatt für Antennenverstärker AB 2
Der Antennenverstärker AB 2 ist ein hochwertiger selektiver Verstärker. Er dient zur Verbesserung der Funksignalstärke bei Einsatz von mehreren Empfängern der Sennheiser evolution wireless Serie an ein Antennenpaar über den passiven Antennensplitter ASP 2. Die Stromversorgung der Verstärker erfolgt über den ASP 2 aus dem Netzteil NT 1, welches auch die Empfänger mit Strom versorgt. Durch die Selektivität werden Funksignale innerhalb des Durchlassbereichs verstärkt sowie Funksignale mit anderen Frequenzen wirksam unterdrückt. Zur Funktionskontrolle besitzt der Verstärker eine rote LED. Es können auch zwei AB 2 innerhalb einer Antennenleitung angeschlossen werden, um eventuelle Pegelverluste bei Verwendung von langen Antennenleitungen zu kompensieren. Dazu wird ein AB 2 direkt an der Antenne (z. B. A 1031-U) und ein AB 2 am Antennensplitter ASP 2 angeschlossen. Die Versorgungsspannung wird vom ersten AB 2 auf den zweiten weitergeleitet (DC-coupled). Wichtig: Beachten Sie beim Anschlie�en des AB 2 unbedingt die Richtung (siehe Typenschild)!

AB 2 antenna booster
The AB 2 is a high-quality frequency-selective antenna booster for increasing the RF signal strength when operating several Sennheiser evolution wireless series receivers with a single pair of antennas via the ASP 2 passive antenna splitter. The antenna boosters are powered via the NT 1 power supply unit of the ASP 2. This NT 1 also powers the receivers. Due to the selectivity of the AB 2, all RF signals within the frequency window are amplified while RF signals on other frequencies are attenuated. Proper function of the antenna booster is indicated by a red LED. In order to compensate for possible signal losses due to long antenna cables, up to two AB 2 can be connected in the antenna cable line: one AB 2 is directly connected to the antenna (e.g. A 1031-U), the second AB 2 is connected to the ASP 2 antenna splitter. The supply voltage is distributed from the first AB 2 to the second (DC-coupled). Important: When connecting the AB 2, it is imperative to observe the direction of signal flow (see type plate)!
