The incredible accuracy of the time alignment, parametric equalization and built-in crossovers make it easier than ever to tune your system perfectly. Housed in a copper plated chassis and powered by an external DC-DC power supply, the DRZ is the only choice for the true audio enthusiast. These numbers represent measurements of an audio signal and other data.
When a digital recording is made, measurements can be made 44, times each second per channel. At that sampling rate, frequencies up to around 20 kHz can be recorded… so the frequency range of conventional CD players barely extends over 20 kHz.
Because the people who set the CD standard believed that no one could hear those high frequencies. If such frequencies were on a conventional CD, the filters in a conventional CD player would remove those frequencies. Furthermore, analog filters can cause phase distortion of the signals that go through them, causing the high frequencies that do come out of the player to come out at the wrong times.
Ironically, high-frequency harmonics can affect the details and the depth of sound. The 96 kHz digital anti-imaging filter interpolates samples into the audio signal from the disc at a speed more than twice as fast as the CD standard sampling rate of This is the first such digital filter designed for vehicle audio. Without oversampling, the signal from a CD must be filtered in the analog domain to reduce high-frequency noise, and such analog filters cause phase time distortion. Oversampling filters are free from phase distortion, so they deliver more musical detail and more of the realistic resonances of real live sound.
The use of a copper plated chassis minimizes the creation of spurious electrical currents that could distort the audio signal. Additionally, the copper plating can reduce noise because it creates an insulating shield.
Zinc has a high specific gravity, high rigidity, and low resonance, so a die-cast zinc panel can reduce distortion caused by vibration. Because components such as the power supply, VFD devices for the display, and the drive mechanism can cause noise in the signal, those components are externally positioned away from the audio signal.
After the data from the disc goes through the kHz filter, it is processed by a Burr-Brown advanced segment bit DAC with superior dynamics and resistance to clock jitter. When the DRZ plays a CD or other source, its display can be turned off to minimize interference from circuits that can otherwise degrade sound quality.
The DRZ is truly an audiophile source unit. This power supply gives the DRZ both strength and precision, and its six-sided shielded casing repels noise even during high-load bursts. To prevent even the smallest vibration, the power supply is wrapped in a die-cast aluminum casing and a copper plated chassis. Toroidal choke coils inside the power supply minimize induced vehicle noise and loss of power.
A large capacity low impedance condenser allows this external component to supply pure power. Clarion takes this one step beyond by equipping this power supply with a gold plated connection terminal to further minimize power loss. This function lets you delay signals going through as many as eight channels so sound from all speakers can arrive at one location simultaneously. Arrival times can be optimized for the driver, front passenger, both front seats, rear seats, or all seats.
Signals can be delayed for differences in distance of up to centimeters over 16 feet in increments of 7 millimeters approximately one forth of an inch.
