High-Resolution Digital Processing

Using the supplied measurement microphone, the DG-78 can analyse the differences between left and right channels and help compensate for the acoustic characteristics of your room. Its Smooth Voicing function is designed to maximise low-frequency performance, while the equaliser provides extensive control for those who want to fine-tune the presentation to their own preferences.

A high-resolution IPS touch display makes the DG-78 remarkably intuitive to use. You can view real-time analyser characteristics, examine the results of the voicing process and even draw your desired response curve using the supplied stylus. Up to 30 different equaliser and voicing configurations can be stored, making it easy to experiment with different system setups or listening preferences.

Who is this for?

The Accuphase DG-78 is designed for serious music lovers and audiophiles who want to take greater control of the sound of their listening system. It is particularly suited to high-end systems where room acoustics, speaker placement or the characteristics of the listening environment are preventing the system from performing at its full potential.

Rather than simply adding more bass or treble, the DG-78 uses sophisticated digital signal processing and real-time spectrum analysis to measure and fine-tune the acoustic response of your room. Its advanced Voicing and Equaliser functions allow you to make precise adjustments while retaining the character and musicality of your system.

It is an ideal choice for high-end two-channel systems, dedicated listening rooms and demanding home audio setups where achieving the right tonal balance is important. With extensive adjustment capabilities, multiple memories and support for high-resolution digital audio, the DG-78 is equally suited to enthusiasts who enjoy experimenting with and refining their system.

What is the Accuphase DG-78?

The Accuphase DG-78 is a high-end digital voicing equaliser designed to measure and fine-tune the tonal balance of an audio system. It combines room analysis, spectrum analysis and sophisticated digital signal processing to help optimise system performance within your listening environment.

What does the DG-78 do?

The DG-78 allows you to analyse the frequency response of your system and make highly precise adjustments to the sound. It can be used to correct room-related tonal imbalances, fine-tune the overall presentation and create different listening profiles.

Is the Accuphase DG-78 a room correction system?

Yes. The DG-78 can be used for room acoustic correction by measuring the response of your loudspeakers and listening environment. Its Voicing function allows you to make precise corrections while retaining the natural character of your audio system.

How many EQ bands does the DG-78 have?

The DG-78 features an 80-band digital equaliser, with adjustments made at 1/6-octave intervals. Its separate Voicing function provides 67 bands of adjustment, also at 1/6-octave spacing.

Does the DG-78 include a measurement microphone?

Yes. The Accuphase DG-78 is supplied with an AM-68 measurement microphone and 5-metre microphone cable, allowing you to measure your system and listening environment.

Can I use the DG-78 with a high-end two-channel Hi-Fi system?

Yes. The DG-78 is particularly well suited to high-end stereo systems where achieving accurate tonal balance is important. It can be integrated into a serious two-channel system between the source and amplifier or through an appropriate digital connection.

Will the DG-78 reduce the sound quality of my Hi-Fi system?

The DG-78 is designed for high-end audio systems and uses high-resolution digital processing to minimise unwanted effects on the signal. With careful setup, it can help improve overall system performance by addressing frequency-response issues caused by the listening environment.

Can I save different EQ settings?

Yes. The DG-78 provides 30 memory locations, allowing you to save different voicing and equaliser settings. This makes it easy to compare different configurations or create profiles for different types of music and listening preferences.

What digital audio formats does the DG-78 support?

The DG-78 supports high-resolution PCM audio through its digital inputs, including PCM up to 384 kHz/32-bit via HS-LINK. It also supports DSD audio up to DSD256 (5.6448 MHz) via HS-LINK.

Can the DG-78 be used with analogue equipment?

Yes. The DG-78 features analogue inputs and outputs as well as a range of digital connections, making it suitable for integration into both analogue and digital high-end audio systems.

Is the DG-78 suitable for home theatre?

Although it can be incorporated into sophisticated audio systems, the DG-78 is primarily designed with high-end two-channel Hi-Fi and critical music listening in mind. Its detailed measurement and voicing capabilities make it particularly suited to enthusiasts who want to optimise a dedicated stereo listening environment.
