DAC IV Firmware
When do I need a Firmware update?
DAC firmware updates offer both corrections of problems we found and performance improvements. We recommend keeping your DAC Firmware up to date. Note: If your version is REV 1.x you must send your DAC back to MSB for updating. You can check the current version of Firmware installed by following these steps:
- Press the menu button on the front panel (left button with square on it)
- Turn the volume knob until ABOUT is displayed
- Click the select button (right button with *)
- You will see CODE REV #
- Then you will see INPUT DSP REV # and FILTER DSP REV #
- The current version should be 4.10, 4.1 and 4.1.
These are the three different upgrade methods possible.
What to expect when doing the firmware update
This update includes three upgrades within the same file, the input DSP, digital filter DSP, and micro all together. The file is several minutes long. Please do not interrupt the process and let the file finish to the end. When you play the file you will hear some instructions, and three upgrade tones. Following each tone you will either hear silence for about 30 seconds (this varies) or you will hear the message ‘upgrade failed’. If all the upgrades fail, it is because you did not play the file bit-perfect. You may have computer upsampling on or digital volume control somewhere in your playback system. Contact MSB if you need help.

Rev. 4.10 Released 10/9/19
This new release adds support and improvements for the Renderer V2. The DAC IV and DAC IV Plus do not support Quad Rate DSD via any interface. Play this file ONLY if you currently have 4.0 or above firmware
DAC V Firmware
When do I need a Firmware update?
DAC firmware updates offer both corrections of problems we found and performance improvements. We recommend keeping your DAC Firmware up to date. You can check the current version of Firmware installed by following these steps:
- Press the menu button on the front panel (left button with square on it)
- Turn the volume knob until ABOUT is displayed
- Click the select button (right button with *)
- You will see CODE REV #
- Then you will see INPUT DSP REV # and FILTER DSP REV #
- The current version is 1.4, 1.1 and 1.1.
What to expect when doing the firmware update
This update includes one update file. Please do not interrupt the process and let the file finish to the end. When you play the file you will hear some instructions, and the upgrade tone. Following the tone you will either hear silence for about 30 seconds (this varies) or you will hear the message ‘upgrade failed’. If the upgrades fail, it is because you did not play the file bit-perfect. You may have computer upsampling on or digital volume control somewhere in your playback system.

The Platinum DAC - Available Upgrades

Femto 140
The Femto 140 is standard with all DAC V’s. Older versions of the DAC IV and DAC IV+ shipped with a lower performance on-board base clock and did not come standard with the femto 140.

Femto 77 (Galaxy Clock)
This is original Femtosecond clock with less than 77fs of jitter. It has been compared and reviewed all over the world with amazingly consistent results. This clock sets a golden standard from measurement and performance.

Femto 33
This is the newest and record breaking clock with less than 33 fs of jitter. So far we have never heard it better than this. This clock has improvements in every area including clock precision, thermal management and a new effort in vibration control. Imagine, half the jitter of the well known Galaxy Femto 77 clock.

Signature Volume Control
Our Preamp philosophy is based on the belief that from the moment analog audio is created, every transition that is made degrades the quality. This is why we have used a passive attenuator within the Signature DAC V and a single OpAmp, to achieve the simplest, shortest possible signal path with the least possible degradation of the true music. The Signature Volume is controlled in 1 dB steps from +9 to -69 dB. Half or quarter db steps can be selected as a menu option. The Volume Control is completely bypassed when at 0 dB.

Diamond Volume Control
This upgrade over the signature volume control includes hand crafted shielding with lower noise measurements.

The DAC V - Features

The DAC V is the heart of a simple reference-level audio system. It has a full array of digital inputs—up to two analog inputs and an integrated analog volume control, easily outperforming most preamps on the market. The DAC V’s numerous inputs and options allow you to perfectly tailor it to your needs. The result is an easy-to-use system that will captivate your aural senses.

Discrete Ladder DAC Modules
MSB’s signature sound is based off our custom designed in-house produced discrete ladder DACs. The Signature DAC V includes 4 ladder modules, while the Diamond DAC V has eight, resulting in neutral, clean, and fatigue-free music.
Signature Preamp
Our preamp philosophy arises from one belief: the moment analog audio is created, every amplifier stage degrades the sound quality. This is why we’ve used passive attenuation and a single buffer stage within the DAC V to achieve the simplest, shortest possible signal path with the least possible degradation of the music. The volume is controlled in 1 dB steps from +9 to -69 dB. The Volume Control is completely bypassed at 0 dB.


Diamond Preamp
For those looking for additional dynamism out of the integrated preamp, the Diamond version is individually tweaked and shielded to provide the lowest noise floor possible, clocking in 5 dB lower than the Signature Volume Module.
The Signature DAC V Inside
The Signature DAC V contains our Signature DAC modules, Femto140, and optional Signature DAC volume controls.

The Diamond DAC V Inside
The Diamond DAC V contains our Diamond DAC modules and cutting-edge technology we learned developing the Select DAC. Expect to hear a level of detail and realism not possible from digital.


The Signature Power Base
The Signature Power Base includes 7 independent transformers and ultra-low noise linear regulators. An isolated independent 12 V DC supply is included for powering a transport.
The Diamond Power Base
The Diamond Power Base extracts the ultimate performance from your DAC V Signature or DAC V Diamond. Each Diamond power supplies is tightly regulated, filtered and shielded, so minimum noise is coupled into the DAC chassis. The Diamond power base uses rapid Silicon Carbide Schottky Diodes that turn on and off instantly with zero reverse recovery current. Like the Signature Power Base, a 12V transport power supply is included.
