The CR-DIG7201-A is a full-digital conference controller built on networked PCM audio encoding/decoding technology, designed as the central host of CREATOR's DIG7 Series full digital conference system. It delivers speech management, voting, simultaneous interpreting, check-in, and computer software control from a single 1U rack-mount unit, with full network transmission from pickup to amplification.
Beyond standard wired discussion units, the CR-DIG7201-A is engineered to support simultaneous use of wired and wireless conference units on the same host — making it a practical core controller for venues that need the reliability of a wireless conference system alongside a stable, low-latency wired backbone. Built-in high-performance DSP processors, adaptive audio algorithms, and equalization technology give the system consistent voice quality whether a delegate is speaking from a fixed tabletop unit or a WiFi-connected wireless unit.
The controller supports ring-network topology and host hot-backup operation, so a single point of failure does not interrupt an active session — an important requirement for government, corporate, and international conference venues running long meetings or multi-day events.
Features
Fully Digital Audio Core
● The conference host adopts fully digital audio encoding and decoding, providing PoE power supply for all conference units, ultra-low latency, and built-in DSP audio processing technology.
● High-fidelity sound quality with lossless audio transmission technology, 48kHz audio sampling frequency, and a 20Hz~20kHz frequency response.
Flexible Network Topology
● Supports partition settings with independently configurable partition volume and sensitivity.
● Hand-in-hand open-loop connection, closed-loop connection, and dual-link communication, plus ring-network connection and host hot-backup for high system stability.
Advanced Audio Processing
● Independent adjustment of unit microphone sensitivity and an 8-segment equalizer (EQ).
● Equipped with digital audio 3A processing technology — AGC (automatic gain control), AFC (automatic feedback suppressor), and AEC (adaptive echo cancellation) — for clear pickup even in acoustically difficult rooms.
Speaking Modes & Voice Control
● Optional speaking modes: Override coverage mode, Open mode, Voice control mode, and Apply application mode.
● Voice control function automatically activates the microphone of the speaker through on-site speech recognition and mutes it automatically when speech ends.
Camera Tracking Integration
● Automatic camera tracking supporting PELCO-P/PELCO-D/VISCA and other common control protocols.
● Supports VISCA, PELCO-D, SAMSUNG, and CREATOR camera protocols; when paired with a CREATOR matrix or central controller, delivers automatic camera tracking, and with a CREATOR HD auto-tracking host and infrared auto-tracking camera, supports wired-unit preset tracking.
Hybrid Wired & Wireless Compatibility
● Supports simultaneous use of wired and wireless conference units on the same host, letting integrators combine DIG7 wired discussion units with CREATOR's WiFi6 series units in one digital wireless conference system deployment.
● Mobile tracking is supported for WiFi conference units, so delegates using a wireless conference microphone system are tracked by camera in the same way as wired participants.
● This hybrid architecture is well suited to venues that want the setup flexibility of a conference system wireless extension in secondary rooms while keeping a wired, PoE-powered backbone in the main hall — for a fully wireless deployment, see CREATOR's WiFi6 Series Full Digital Wireless Conference System.
Software & Interface Management
● PC software provides unified management of units and intelligent fault analysis — types, quantities, distribution, and faults of conference units can all be reviewed centrally.
● Equipped with Phoenix and Canon audio output interfaces, supporting balanced and unbalanced output, conference-unit partitioning, and 4-channel speaker partitioning output; any output interface can be configured to connect to remote video conferencing systems.
● Independent adjustment of line-in, remote video conference input, 5-channel audio output, and conference-unit volume, with a mute range of -40dB to 0dB.
Simultaneous Interpretation & Voting Ready
The audio backbone of the CR-DIG7201-A is built to work alongside CREATOR's infrared simultaneous interpretation hardware, giving multi-language conferences the option to add a wireless simultaneous interpretation system for delegate headsets without re-architecting the core audio network. Combined with the controller's built-in voting and check-in functions, this makes the CR-DIG7201-A a suitable host for international conference halls, courtrooms, and multi-language corporate boardrooms.

Applications
Government & International Conference Halls — ring-network topology and host hot-backup support long, uninterrupted multi-day sessions with voting, check-in, and simultaneous interpreting.
Corporate Boardrooms — hybrid wired/wireless unit support lets rooms mix fixed tabletop discussion units with a wireless conference room microphone system for flexible seating.
Courtrooms & Multi-language Venues — pairs with CREATOR's infrared interpretation hardware to add a wireless simultaneous interpretation system without replacing the core audio network.
Multi-purpose & Divisible Rooms — partition settings and 4-channel speaker zoning make it suitable for spaces that need independent audio control per section.
Remote & Hybrid Meetings — balanced/unbalanced outputs connect directly to remote video conferencing systems, supporting rooms that function as a wireless video conference system endpoint alongside in-room participants.
FAQ
Q: Is the CR-DIG7201-A a wired or wireless conference system?
A: The CR-DIG7201-A is a full digital, PoE-powered wired conference host built on networked PCM technology. It supports simultaneous use of wired and WiFi wireless conference units on the same system, so it can serve as the core controller for a hybrid room. For a fully wifi conference system deployment, CREATOR's WiFi6 Series is the dedicated wireless product line.
Q: Can wireless units be mixed with wired DIG7 units on the same host?
A: Yes. The system supports simultaneous use of wired and wireless conference units, and WiFi conference units also support mobile camera tracking, so delegates moving with a wireless unit are still tracked correctly.
Q: Does this controller support simultaneous interpretation?
A: Yes, the CR-DIG7201-A's audio architecture is designed to work with CREATOR's infrared simultaneous interpretation system, allowing multi-language conferences to add interpreter channels without changing the core audio network.
Q: What happens if the host fails during a live session?
A: The system supports host hot-backup operation and ring-network connections, so the conference can continue with minimal interruption if the primary host experiences an issue.
Q: Can it integrate with existing PTZ cameras?
A: Yes, it supports PELCO-P, PELCO-D, VISCA, SAMSUNG, and CREATOR camera control protocols, enabling automatic camera tracking when paired with a compatible matrix, central controller, or auto-tracking camera host.
