Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
External DAC (Digital-to-Analog Converter): The Meridian Director is a
high-quality DAC designed to deliver superior audio quality from today's digital
sources, including computers media players, as well as legacy digital sources
such as CD players, when listened to on an analog audio system. The Director out performs the inferior DACs found inside your
computer, laptop, network player, music server, or CD player. The Director
will breathe new life into all your digital audio sources.
Premium Audiophile-Grade Components: Audiophile-grade
components are utilized throughout the Meridian Director. The Director is enclosed in a sturdy, durable
anodized aluminum extrusion case with molded end-caps. The external DAC features
a sophisticated 4-layer PC board and direct-coupled to minimize noise and
improve audio performance. The Director incorporates the highest quality
components throughout, including audiophile grade capacitors, resistors. and
gold-plated RCA sockets.
High Resolution Audio: The Director supports sample
rates up to 24-bit, 192kHz and incorporates Meridian Resolution Enhancement
technologies, including Meridian Upsampling and the Apodising filter, which
audibly improves audio quality. The proprietary Apodising filter can actually
improve the sound of some digital recordings by fixing recording faults.
Standard sample rate signals (16-24 bit, 44.1/48kHz) are automatically upsampled
to 24-bit/88.2kHz or 96kHz, allowing filtering to be carried out far above the
range of human hearing.
Asynchronous + Low Jitter: The Director operates asynchronously using
on-board, high-quality, discrete audio clocks for the USB and S/PDIF input,
rather than low-quality audio clocks derived via USB from your computer. The
Director's master clocking is done by separate precision reference oscillators
for base sample rates (44.1 kHz/48 kHz) to minimize jitter and distortion.
USB Port (MAC/Windows Compatible): The Meridian Director
connects to your desktop computer or laptop's USB (type-A) port via the DAC's
USB (type-B) port; USB cable sold separately. The USB (type-B) socket allows the
Director to be connected to your computer for playback of
computer-based sources such as network audio and music server files, far exceeding the
audio performance of a standard computer sound card. The Director can connect to virtually any
computer with a USB port. Drivers for Windows; Macintosh, and Linux operating
systems allow simple plug & play operation. The interface is USB Audio Class
Compliant 2.0 HS, supporting 24-bit/192kHz resolution and data rates up to 480Mb/s.
Note: The Director supports Macintosh OS X 10.6.4 (Snow
Leopard) or later; no additional drivers are needed. The Director is also
compatible with Windows XP SP3, Windows 7 SP1, or Windows 8; additional
drivers are required and can be downloaded from the
Meridian Support Site. In addition, the Director supports Linux kernel
2.6.37 or later.
Digital Input: The digital input lets you connect your CD player,
Blu-ray player, or music player with a digital output. This 3.5mm hybrid socket provides input for S/PDIF digital signals
(2ch PCM only) via a 3.5mm mono jack. Two adaptors
are included; one allows standard coaxial S/PDIF RCA cables to be used with
Director, while the other allows standard Toslink optical cables to be used. The
Director supports 24-bit/192kHz via the coax adapter and 24-bit/96kHz via the
Analog Outputs: The Meridian Director is designed for connection to an
analog audio system via its fixed-level stereo RCA outputs (2v RMS). The RCA
outputs include anti-thump circuitry for trouble-free performance at switch-on.
LED Indicators: Three LEDs indicated the DAC's source input
(Analog/SPIDF/USB). Three other LEDs indicate the input sample rate. When the 1x
LED is illuminated, the Director is receiving a signal at 44.1 or 48kHz
sampling: (upsampled to 88.2/96kHz). When the 3x LED is illuminated, the unit is
receiving 88.2/96kHz. When the 4x LED is lit, 176.4/192kHz is being received.
Power Requirements: The Meridian Director can operate off of
standard household current using the supplied AC power adapter. The Director can
also be powered by a free USB (type-A) port on your computer.
Firmware Updates: Firmware updates can be downloaded from
Meridian Support Site to your computer and the connected Director DAC.
