Description
The Yamaha Rio3224-D2 is a high-performance I/O rack designed for use with Yamaha’s digital mixing consoles (such as the RIVAGE PM, CL, and QL series). It represents a significant evolution from the original Rio series, offering enhanced sound quality, improved reliability, and better visual feedback.
Core Specifications
-
Analog Inputs: 32 (featuring high-end recallable mic preamps).
-
Analog Outputs: 16.
-
Digital Outputs: 4 AES/EBU outputs (8 channels total).
-
Network Protocol: Dante (Primary and Secondary ports for redundancy).
-
Sample Rates: Supports 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz.
Key Features & Enhancements
-
Pristine Audio Quality: The “D2” version features upgraded analog circuitry compared to the original Rio, delivering a more transparent and natural sound that Yamaha calls “Natural Sound” philosophy.
-
Dual Power Supplies: It includes built-in redundant power supply units. If one power source fails, the unit continues to operate without interruption—a critical feature for live broadcast and high-stakes events.
-
Character Display: Unlike the first generation, the D2 features an onboard display that allows for quick monitoring of gain settings, high-pass filters, and phantom power status directly from the front panel.
-
Daisy Chain or Redundant Mode: You can choose between a simple “Daisy Chain” setup or a fully “Redundant” network configuration to ensure the audio signal never drops.
-
Dante Device Bridge: It supports the Dante “Device Bridge” feature, allowing for easy integration and control within complex network infrastructures.
| Feature | Benefit for Broadcast |
| Dante Integration | Seamlessly connects with your Ross Acuity (via IP) or other networked gear for a fully digital workflow. |
| Gain Compensation | Allows multiple consoles to share the same Rio unit. If one engineer changes the analog gain, the Rio digitally compensates so other consoles don’t experience a volume jump. |
| Low Latency | Dante protocol ensures near-zero latency, which is vital for lip-sync accuracy in live TV. |
| Rugged Build | Designed to withstand the heat and vibration of OB vans and touring racks. |
Ideal Use Cases
-
Live Broadcast Studios: Handling a large number of microphones and IFB (interruptible foldback) returns via a single network cable.
-
Outside Broadcast (OB) Vans: Acting as the primary stage box for remote sporting events where long-distance signal integrity is non-negotiable.
-
Large Concert Venues: Distributing high-quality audio across a wide Dante network with total reliability.
