Maintenance
Use a soft dry cloth to wipe the surfaces of the units clean.
For stubborn smudges, use a damp cloth that has been thoroughly wrung out to remove excess moisture.

  • Never spray liquid directly on these units.
  • Do not wipe with chemical cleaning cloths, thinner, or other chemical agents. Doing so could damage the surfaces of the units.
  • Avoid allowing rubber or plastic materials to touch the units for long periods of time because they could damage the cabinets.
    For safety, disconnect the power plugs from the outlets before wiping the units.

Precautions for use

  • These units are very heavy, so take care to avoid injury during installation.
  •  Do not install these units in locations that could become hot. This includes places that are exposed to direct sunlight or near a radiator, heater, stove, or other heating equipment. Moreover, do not place them on top of an amplifier or other equipment that generates heat. Doing so could cause discoloration or deformation.
  • Avoid locations that are extremely cold or exposed to excessive humidity or dust.
  • In order to enable good heat dissipation, leave at least 20 cm (8″) between these units and walls and other equipment when installing them. If you put them in a rack, take precautions to prevent overheating by leaving at least 5 cm (2″) open above the tops of the units and at least 10 cm (4″) open behind them. Failure to provide these gaps could cause heat to build up inside and result in fire.
  •  Place these units in stable locations.
  •  Do not place anything on top of the units.
  •  Do not put the cloth on top of the units or place them on top of bedding or thick carpet   Doing so could cause them to overheat or damage them.
  • The voltage supplied to the units should match the voltage as printed on the rear panels. If you are in any doubt regarding this matter, consult an electrician.
  •  Do not move the units during use.
  •  Do not open the bodies of the units as this might result in damage to the circuitry or cause electric shock. If a foreign object should get into one of the units, contact your dealer.
  •  When removing a power plug from an outlet, always pull directly on the plug. Never pull on the cord itself.
  •  The ES-LINK format is unique to ESOTERIC and is not compatible with the HDMI specification. Do not connect the ES-LINK connector to an HDMI connector on a device made by another company.

Connections

Connecting using ES-LINK Analog

ESOTERIC Grandioso D1X Monoblock DAC Set - fig

  • Use XLR cables to connect the analog audio output (XLR/ESL-A) connectors on these units to an amplifier that has ES-LINK Analog (ESL-A) connectors.
  • Set the analog outputs (AOUT) for the units to ESLA.
  • You can also connect using XLR or RCA connectors. Select the connection type that provides the audio quality you prefer.

ES-LINK Analog overview
The current transmission method utilizes the performance of HCLD buffer circuits that feature the ability to supply strong current at high speed. This suppresses the impact of impedance on signal paths, enabling pure and powerful transmission of signals.

  • Ordinary balanced cables (with XLR connectors) are used for the connection. These connectors can only be used with compatible devices, however, because the transmission format is unique.

ESOTERIC Grandioso D1X Monoblock DAC Set - fig 1

Precautions when making connections

Moreover, be aware that the problem might be caused by something other than this product. Please also check the operation of the connected units. If this product still does not operate correctly, contact the retailer where you purchased it

The Grandioso D1X does not turn on.
Confirm that the power cords are securely connected to the inlets on the backs of the units and to the power outlets.
Confirm that power is being supplied to the outlets to which the power cords are connected by, for example, connecting other devices to them.
One or both units automatically turn off.
This is because the automatic power-saving function turned the unit(s) off.
Press the POWER button on a unit to turn it on. Change the automatic power- saving setting(s) if necessary (page 15).
No sound is output from the speakers. The sound is distorted.
Turn the power off and check the connections with the digital audio source device, the amp, and the speakers (page 8).
Change the input set to the connector that is being used for input (page 12).
Set this product’s analog output (AOUT) setting according to the amp connection (page 15).
Adjust the volume of the amplifier and other devices.
No sampling frequency for the input signal is shown on the display.
Turn the device that is connected to the selected input connector on.
Confirm that the device is properly connected to the selected input connector.
“– – –” appears in the sampling frequency display area.
There is a problem with the input signal. Do not input signals other than PCM or DSD. Check the connection with the digital device. This unit cannot decode signals in formats such as Dolby Digital, DTS, and AAC. Have the playback device convert the signal to PCM before output.

A cyclical noise is being output.
If a cyclical noise is being output when the Grandioso D1X is in clock mode, the connected device might not also be in clock mode . Check the connection status of the clock connectors and the clock settings of connected devices.

The CLOCK indicator does not stop blinking.
Set CLK> to OFF when not using clock sync (page 14) .
A clock signal to which the unit cannot synchronize might be being input. Check the connection status of the clock connectors and the settings of connected devices . The Grandioso D1X only supports a 10MHz clock.

Since the Grandioso D1X uses a microcontroller, external noise and other interference can cause it to malfunction. If this occurs, turn the product off once, and then restart it after waiting for about one minute.
