Product Description
Product Name: NUOVA MAREA NM-251A Two Channel Multiplier Unit
Model: NM-251A (Part of the NM-251 Series)
Version: Hardware/Firmware Ver 1.00
Manufacturer: Nuova Marea Ltd (Likely a specialized or regional OEM/manufacturer)
Primary Function: To take one or two input signals, amplify them, and output multiple, identical, isolated copies of each signal to drive several downstream devices without signal degradation.
Key Features :
-
Dual-Channel Design: Two independent multiplier/amplifier circuits in one chassis. Can handle two separate signal sources simultaneously (e.g., Audio Left & Right, or two different video feeds).
-
Signal Multiplication/Distribution: Each channel likely takes 1 input and provides multiple identical outputs (e.g., 1-in, 4-out or 1-in, 8-out per channel). The exact number of outputs is not specified by “NM-251A.”
-
Amplification & Equalization: Amplifies the signal to compensate for cable loss and may include level/gain controls. Could feature cable equalization for long cable runs.
-
High Isolation Outputs: Prevents interference and feedback between connected devices. A load on one output does not affect the others.
-
Format Specific: The exact model suffix (A) likely denotes a specific signal type:
-
If Audio: Likely a Stereo Audio DA. Would use XLR, TRS, or RCA connectors. May handle mic or line-level signals.
-
If Video: Likely a Video DA for SD/HD-SDI, HDMI, DVI, or analog video (Composite, Component). The “VER 1.00” suggests it might be for a specific digital video standard.
-
If Control/Data: Could also be for RS-422/RS-485 serial data, MIDI, or timecode (LTC) distribution.
-
-
Rack-Mountable Design: Standard for professional equipment.
Typical Applications:
-
Broadcast Studios & Trucks: Distributing camera feeds, reference video, or audio mixes to multiple monitors, recorders, and control rooms.
-
Live Sound: Sending master audio signals to multiple power amplifier racks or recording splits.
-
Post-Production Suites: Duplicating video or audio signals for various editing and monitoring stations.
-
Digital Signage: Distributing a single source to multiple displays.
-
Installation AV: Sending signals from a Blu-ray player or media server to numerous TVs or projectors.
