Diamond DAC IV Details
Back

Each DAC must be attached to a Platinum Power Supply. Each power supply comes with an output, able to operate a DAC or ADC AND an output to operate an MSB transport. In this case we reccomend only a Diamond. See Power Base Comparisons.

The Diamond Power Supply includes upgraded capacitors, silicon carbide diodes, addtional magnetic and electrostatic sheilding. It also provides twice the power output and an exceptional Power Link Cable.

The Power Base is controlled with a toggle switch on the rear panel for via a 12 V trigger connection also on the rear. This upgrade provides a front panel switch as well as remote receiver so the power supply can be turned on and off with the MSB remote.

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 Platinum DAC IV, to achieve the simplest, shortest possible signal path with the least possible degradation of the true music.  The Volume is controlled in 1 dB steps from +9 to -69 dB.  The Volume Control is completely bypassed when at 0 dB.  The Diamond volume control is hand selected and carefully shielded for a truly transperent volume control.

The volume control can be applied to the analog inputs or the inputs can bypass the volume control. Trim and balance can be selected in the DAC menus to match the DAC output to an external analog input.

This Wi-Fi interface will allow iPhone/iPod/iPad control of up to 6 MSB or non-MSB products. Free Apps are available for various system configurations and for a charge can be customized.

WiFi System Interface

We have gone to great trouble to completely isolate the USB input from computer noise and jitter. The USB receiver is actually powered from the USB computer power and the data buffered and optically coupled to our board for complete ground isolation and jitter rejection. Listening tests place this input on an equal footing with other SP/DIF inputs, as a truly high performance audio source. The USB input is availible in three levels. All are limited to 24 bits.

USB1 will work to 48k with no special drivers, installation or preparation on the computer. Plug it in and go.

USB2 Standard 192 is a more advanced option, with bit-perfect playback of all files up to 192 kHz. Plug and play on the MAC, but MSB drivers will need to be installed on the PC.

The USB2 Signature 384 upgrade will play all files up to 384 kHz with exceptional quality. Plug and play on the MAC, but MSB drivers will need to be installed on the PC.

Up to Two USB inputs can be added of any type.

There are two possible upgrades to add an additional analog input. One adds another balanced input, the other a single-ended input.

The single-ended input upgrade converts the Alternate Analog Output into an additional single-ended analog input. Just as the balanced analog input, it can bypass or use the volume control and is fully selectable.

A second balanced input can be added by using the two AUX inputs for two more XLR inputs. Just as the first balanced analog input, it can bypass or use the volume control and is fully selectable. This upgrade uses up the AUX inputs so no other digital inputs can be added.

This input provides a ground isloated MSB Network input ideal for connection to the Universal Media Transport as well as our Flagship Transports.

Both MSB Network I and MSB Network II are supported. Can be installed in either AUX input slot.

This upgrade provides an iPod input in the cover. This second generation MSB iLink will work with all unmodified iPods since the Generation 5 iPod Video used by the iLink.

It provides a high-quality digital link to the iPod and occupies one of the optional digital inputs. This is a field installable upgrade that only requires replacing the cover. iPod not included.

This new clock offers unprecedented accuracy with jitter under 77 femtoseconds (.077 psec). There is no more accurate clock availible for audio. Sonic benefits guaranteed.
