The AS8X4 Active Splitter is a 1 rack space, 8-channel active microphone splitter
providing 4 isolated outputs per channel. It features:
• Professional quality mic preamps driving premium quality Lundahl LL1581XL
transformers. This eliminates microphone loading effects characteristic of passive
splitters
• 4 transformer isolated outputs optimized for transmitting audio down long cables
• All I/O connections via plug-in Phoenix style screw type terminal strips
• 48-volt phantom power with on/off switch and indicating LED provided on each
channel
• 20dB input pad
• Listen (cue) feature on each channel
• LED headroom indicators on each channel
• Ground lift switches on all isolated outputs
• Internal switches allow 3 different gain settings of the mic preamp
• 2 additional internal jumpers (user changeable without soldering) engage post mic
preamp 20dB pads for flexibility in setting different gain structures for various
cable lengths
• Up to 80 channels of split are capable with multiple units and the appropriate
power supply
• Modular design allows for future expansion and individual units are easily
changed in the unlikely event they need servicing
• Power supply and monitor are a separate unit and utilize various wattage supplies,
depending on the number of channels in the system
• Monitor section features a high power headphone driver and VU meter for instant
cueing of individual channels
Description of Block Diagram
All audio input and output connections are done via a plug-in type Phoenix style screw
type barrier strips. Each inline strip accommodates 4 channels. On the back panel, all
input and iso outputs are separate groups. The strips allow termination of wire ends
without the splitter unit present and provide for quick and easy connect/disconnect. The
Direct IN/OUT terminations, which accept a mic level input, are used for generating a
direct-wired parallel output should a 5-way splitter be desired.
Each channel has its own phantom power on/off switch with LED indicator. When
engaged, 48 volt phantom power is placed on the Direct IN/OUT + and – terminals. The
individual phantom power on/off switches allow worry free hook up to electronic
equipment not able to block the 48 volts DC.
After the input, the signal passes thru a 20dB pad. This allows input of line signal levels
up to +20dBm.
