Sennheiser SL PASC 4: Four-Channel Passive True Diversity Antenna Splitter/Combiner for SpeechLine Digital Wireless Series

The Sennheiser SL PASC 4 is a high-performance, passive, four-channel true diversity antenna splitter/combiner designed specifically for Sennheiser’s SpeechLine Digital Wireless microphone series. Engineered to optimize the antenna configuration for SpeechLine systems, the SL PASC 4 allows users to manage and streamline antenna signals from up to four SpeechLine Digital Wireless channels, simplifying setups for conference halls, auditoriums, corporate boardrooms, and educational environments. Its robust design and advanced antenna management help minimize interference and ensure that each SpeechLine wireless channel receives consistent and reliable signal strength.

Key Features and Benefits

1. True Diversity Antenna Splitting for Reliable Signal Quality

• The SL PASC 4 is a true diversity antenna splitter, which means it distributes the antenna signal to each connected receiver in a way that minimizes dropouts and interference. In a true diversity system, the device actively selects the antenna with the strongest signal, ensuring uninterrupted audio transmission and improved overall system stability.
• By using a true diversity splitter like the SL PASC 4, venues can enhance the quality of their SpeechLine Digital Wireless setup, particularly in challenging RF environments where signal interference can be an issue. This feature is invaluable for professional settings where consistent audio quality is essential.

2. Supports up to Four SpeechLine Digital Wireless Channels

• The SL PASC 4 can handle up to four SpeechLine Digital Wireless radio links, making it an ideal choice for systems with multiple microphones or wireless audio devices. Instead of needing individual antennas for each wireless channel, users can connect all four channels to a single set of remote antennas, significantly reducing the number of required antenna cables and simplifying the setup.
• This configuration allows for a more organized and efficient setup, which is especially beneficial in large venues or installations with multiple channels. Audio engineers and technicians can rely on the SL PASC 4 to manage multi-channel setups without cluttering the space with excess cables or antenna equipment.

3. Seamless Integration with AWM 2 and AWM 4 Remote Antennas

• For enhanced performance, the SL PASC 4 is compatible with AWM 2 and AWM 4 remote antennas (both available separately). By pairing the SL PASC 4 with one of these remote antennas, users can maximize coverage across large or complex spaces, ensuring consistent signal transmission even at a distance from the source.
• Using a remote antenna also enables better control over the placement of the antennas, allowing for greater flexibility in challenging environments, such as large auditoriums or conference spaces with obstructions. This compatibility with remote antennas makes the SL PASC 4 an adaptable solution for various venue layouts and configurations.

4. Minimizes Required Antenna Cables for Cleaner Setups

• One of the key benefits of the SL PASC 4 is that it reduces the number of antenna cables required in a multi-channel setup. By consolidating antenna signals for up to four SpeechLine Digital Wireless channels, it minimizes clutter and makes cable management more manageable, resulting in a cleaner and more professional appearance.
• In addition to improving aesthetics, reducing the number of cables also decreases the likelihood of signal interference, which can result from excessive cabling in RF environments. This streamlined approach ensures that each wireless channel performs at its best, free from unnecessary noise or signal degradation.

5. SMA-RP Cable Connections for Easy Setup and Integration

• The SL PASC 4 comes with SMA-RP (reverse polarity) cables, which are used to connect the splitter to the SpeechLine Digital Wireless rack receivers. These cables provide secure, interference-resistant connections, ensuring stable signal flow between the antenna splitter and the receivers.
• The SMA-RP connectors are easy to connect and disconnect, allowing technicians to quickly set up and dismantle the system as needed. This feature is especially useful for rental equipment or setups that require regular reconfiguration, as it simplifies the process of connecting and managing multiple devices.
