Skjerm- og panelkontroller

The R30 utilizes a large OLED display for real-time status monitoring and functional operations. The diagram below illustrates the main interface display states.

1. OLED-skjerm

The display shows the input channel, external clock indication, encoding format, sampling rate, and volume.

2. Input Channel Selection

R30 har 7 inngangskanaler. På hovedgrensesnittet vil hvert trykk på girknappen bla gjennom tilgjengelige kanaler i denne rekkefølgen: COAX → AES → OPT → USB → STREAMER → IIS(G) → IIS(M*).

***Note: IIS(G) is for fixed Gustard pinout configuration and cannot be adjusted. IIS(M*) supports adjustable pinout configuration.

3. Volumjustering

• When the main interface is displayed, pressing the "+" or "-" buttons directly adjusts the analog volume attenuation function of the passive preampDempingen varierer fra 0 dB til -63.5 dB (total 63.5 dB demping).
• Pressing "+" at 0dB activates Fixed Output mode (bypassing attenuation circuit), displaying 'FIXED' indicator.
• When 'FIXED' is displayed, pressing "-" first exits bypass mode before controlling the attenuation level.

Oppsettmeny

On the main screen, long press the Gear Button to enter the settings menu (hereinafter referred to as the menu button). In this state, the menu button can sequentially switch the menu items to be modified. "+" and "-" buttons are used to adjust the currently selected menu options. When the screen is in the settings menu, long press the menu button again to return to the main screen.

Menyfunksjoner

Åpne menyen ved å trykke på menyknappen i hovedgrensesnittet. Hvert menyalternativ er beskrevet nedenfor.

1. PCM FILTER (PCM Digital Filter Adjustment)

R30 benytter en egenutviklet PCM-overs med høy ytelseampLing digital filtermodul med tre filtertyper:

• VIVID (Default): Similar to the FAST roll-off type of traditional digital filter, but with better ringing characteristics, very small pre-ringing, and fast convergence post-ringing. It aims for a broad soundstage and sound restoration. Recommended for most music styles.
• GENTLE: Similar to the SLOW roll-off type of traditional digital filter, offering a soft listening experience.
• SAMMENSATTE: A hybrid digital filter, balancing characteristics between Vivid and Gentle for a good listening experience.

2. DSD FILTER (DSD Digital Filter Adjustment)

DSD-filteret har fire innebygde båndbreddealternativer: 47K (Default), 50K, 60K, 70K.

3. NOS-MODUS (Ingen oversampling Filter Mode)

When enabled, the PCM signal bypasses the oversampling filter entirely, decoded straight through the R-2R decoder module. This preserves micro-details and timing integrity. When enabled, there may be a slight clicking sound when the playback data format switches between PCM and DSD.

• DISABLE (Default)
• AKTIVER

4. REF CLOCK (Reference Clock Selection)

The GUSTARD-K2, low-noise clock synthesizer, achieves ultra-low jitter performance. The R30 offers two clock options:

• INTERNAL (Default): Uses the built-in OCXO internal reference.
• EXT. 10MHz: Selects an external 10MHz reference source. It is recommended to connect to GUSTARD C16 or C18 reference 10M master clocks.

If the external clock is lost, powered off, or its frequency deviation is greater than +/-150ppm, "EXT ERR" will be displayed and flash.

5. IIS MODE (IIS Pinout Mode Selection)

R30 har to IIS-inngangsgrensesnitt:

1. IIS(G): Fixed Gustard pinout protocol (non-adjustable). DSD playback requires a DSD FLAG signal from the source device.
2. IIS(M*): Har justerbar pinout-konfigurasjon. Den automatiske deteksjonsfunksjonen for PCM- og DSD-koding eliminerer behovet for FLAG-signaler.

IIS(M*) adjustable Pinout mode IIS input has four Pinouts: MODE1 (Default), MODE2, MODE3, MODE4. MODE1 is compatible with the GUSTARD mode. If you are connecting to a GUSTARD front end such as U12, U16, U18, S16, S26, etc., you can match them with MODE1, which is the former works in the Gustard output mode.

Please do not connect to the usual HDMI, this is not really HDMI.

6. PHASE (Phase Setting)

Denne funksjonen tilbyr to alternativer:

• NON-inverted (Default): When non-inverted, the RCA output of R30 is normal phase, and the XLR balanced output is American standard polarity output (1 ground, 2 hot, 3 cold).
• Invertert: When inverted, only the RCA output is reverse phase, and the XLR balanced output is Japanese/European standard polarity output (1 ground, 2 cold, 3 hot).

7. TRIGGER CH. (Linkage Trigger Start Channel Selection)

The R30 can be triggered by an external 12V linkage signal and automatically turn on from standby mode. When the 12V trigger signal ceases or drops to 0V, automatic standby activation occurs. When the R30 is working, it is switched to the input channel of this setting by the 12V trigger linkage signal.

• LAST (Default): The input channel that was in use before entering standby last time.
• Other options include COAX, AES, OPT, USB, STREAMER, IIS(G), IIS. Selecting any channel activates it upon receiving a 12V trigger signal.

8. TRIGGER VOL. (Link Trigger Boot Volume Selection)

R30 kan slås på fra standby via et eksternt 12V triggersignal og automatisk stilles inn på valgt volumnivå. Alternativt, under drift, vil et 12V triggersignal bytte utgangen til forhåndsinnstilt volum. Dette alternativet konfigurerer utgangsvolumet etter triggeraktivering.

• LAST (Default): The volume used before entering standby.
• FIKSET: Fixed full-scale output bypassing attenuation.
• -20dB: Output at a volume attenuated to -20dB.
• -30dB: Output at a volume attenuated to -30dB.
• -40dB: Output at a volume attenuated to -40dB.

9. DISPLAY (Screen Brightness Settings)

Long-term high-brightness use of OLED screens can cause screen burn-in or ghosting. Therefore, the R30 is designed to always select automatic screen off, or manually select automatic screen off, which can also reduce interference.

• AUTO (Default): Automatically reduce brightness.
• AUTO AV: Automatically turn off the screen.

Infrarød fjernkontroll

Når du bruker DAC-produkter, trykker du på og holder inne DAC-knappen i over 3 sekunder for å gå inn i DAC-kontrollmodus. AMP/STREAM-moduser styrer andre Gustard-produkter.

1. Standby: Press once to activate R30 from standby. Press once during operation to enter standby.
2. Meny: Press to access R30's setup menu.
3. Pad med 4 retningstaster: Up/Down navigates menu items. Left/Right adjusts selected options. Center press activates/deactivates mute.
4. Tilbake: Returns to main interface.
5. Vol-: Decreases output volume on main interface.
6. Vol+: Increases output volume on main interface.

Merknader:

• Operational range varies with angle.
• Obstructions between remote and sensor may cause malfunction.
• Remove batteries if unused for more than 1 month.
• Thoroughly clean battery compartment if leakage occurs.
• May accidentally trigger other IR-controlled devices.

Hurtigstart for nettverksbro-streamer

After connecting R30's RJ45 port to your local network:

1. Select the STREAMER channel and await system boot (approximately 1 minute, until "DSD 24.5MHz" appears).
2. Access R30's configuration page via: http://R30.local (as shown below). Disable unused streaming protocols on the web grensesnitt for å maksimere systemeffektiviteten. Fastvareoppdateringer utføres også her.

(Drift på mobil/nettbrett venter inntil dedikert app lanseres)

You can turn off streaming protocols that are not frequently used through the web page to maximize system music playback performance. At the same time, the online upgrade of the Streamer is also operated on the web side.

(Etter at den dedikerte Streamer-appen er startet, kan operasjonene ovenfor utføres i appen)
