GRACE design m905 Reference Monitor Controller (with dedicated remote controller) [Official Japanese Product] (Pre-order item, delivery date to be announced separately)

The core of the product. The reference monitor controller has been reborn with enhanced functionality.

*New firmware supports DSD 64x (2.8224 MHz) playback!
Supports DoP v1.1, enabling DSD playback from AES3, S/PDIF or USB digital input.


~ A monitor controller truly worthy of being called a "reference" ~

A powerful upgrade to the m904 monitor controller, used by top studios around the world.
Perfectly designed down to the smallest detail and featuring "professional engineering," this monitor controller truly deserves to be called a "reference."

With a redesigned s-Lock PLL, asynchronous USB connection (24-bit/192kHz), and a new analog circuit design that meticulously considers every detail, the AK4110 delivers a significant upgrade in sound quality, providing a highly accurate, musical, mastering-quality playback environment for any input source.
The m905 system consists of a 2U rack-mounted main unit (ACU) and a remote controller (RCU) equipped with a color LCD display.
All functions can be operated with hardware switches and rotary encoders, allowing for stress-free operation, and the highly visible LCD display interface ensures reliable operation.

In addition, the "Setup mode," which has been thoroughly researched for ease of use in professional studios, allows you to quickly change the names of each input and output, as well as set level offsets and preset levels and other detailed calibration settings.

The most reliable and beautiful reference monitor controller.

Comprehensive I/O: Comprehensive management of all studio playback. Fully equipped with all analog and digital inputs, and outputs including three speaker systems, headphones, cue/meter/subwoofer, and digital through, it provides powerful support for any situation. A newly added asynchronous mode-compatible USB port enables 24-bit/192kHz PC playback.

The m905 has everything you need in a studio central controller.

●Commitment to sound quality: The quality unique to GRACE design, which adheres to reference sound.
The latest DAC design and s-Lock PLL low-jitter reclocking technology deliver a dramatic improvement in sound expression. Asynchronous USB playback also ensures bit-perfect PC playback. The renowned analog circuitry has been further refined to achieve a higher dynamic range. Precision 0.5dB-step level controls ensure precise sound reproduction.

Its greatest appeal is its ability to reproduce the original sound transparently, making it truly worthy of being called a "reference."

Intuitive operability
The m905RCU features a highly visible color LCD display. Combined with hardware switches and rotary encoders, it offers unprecedented intuitive operation. No matter what operation you perform, you'll reach your desired function in simple steps.

Input/output name editing, status display, powerful calibration functions, and more can all be performed quickly and accurately.

Highly flexible functions
The m905 is packed with countless features to suit any situation. The Setup menu allows you to perform detailed calibrations, including setting input and output level offsets, MONO/DIM/MUTE, subwoofer/DAC/meter output, headphone output, CUE output, digital output, word clock, de-emphasis, and S/MUX settings.

The m905RCU is also equipped with a microphone, allowing it to be used for talkback (an external microphone can also be used) or for real-time SPL measurement. It is a full-fledged SPL meter that can also be configured with measurement filters, dynamic characteristics, peak display, and more.
