Yamaha IMX644

Comprehensive I/O in a Compact 2U Unit
With six mono analog inputs, four stereo analog inputs, and two stereo analog outputs plus a dedicated stereo output for recording, the IMX644 offers an ideal I/O configuration for small to medium size installations.

Easy Panel Operation and Memory Recall
The front panel features input and output level controls as well as four buttons for memory recall. These controls allow users who do not have any specialized knowledge to easily operate the mixer's main functions. The internal memory can store up to 16 mixer setups, four of which can be recalled directly from the front panel. Memory recall is particularly useful in general facilities such as event spaces and banquet halls where it allows appropriate settings for specific situations to be recalled in an instant.

Feedback Suppression on All Six Mono Inputs
Since the most likely sources for the mono inputs will be microphones, feedback suppression is provided on all six mono inputs. Both pre-settable filters and automatic detection systems are implemented for effective prevention of feedback under widely varying acoustic conditions.

Optical Digital Inputs for Direct Connection to Digital Sources
CD players, DVD players, and other audio sources that have optical digital outputs can be directly connected to the IMX644. Built-in sample rate conversion eliminates the need for word clock settings or synchronization.

Auto-ducking Gives Priority to Announcements
This feature automatically reduces the volume of the background music or other program material when input is applied to a specified channel. Auto-ducking is effective for a range of situations, from announcements to emergency broadcasts.

Speaker processing data pre-installed
IMX644 Manager software has processing data for Yamaha installation speakers preinstalled. Once the system is set up, simply recall these settings for optimized audio performance
