Welcome to the 888
UNPRECEDENTED RECORDING POWER - ON A CART OR OVER THE SHOULDER.
Meet the 888 - the portable mixer-recorder that’s compact and light enough to use in a bag, yet has the high channel count and power required
for mobile cart productions. The 888 is the smallest portable mixer-recorder on the market that offers Dante for sending and receiving audio over
Ethernet. With 8 ultra low-noise, 8-Series microphone preampliers, 16 channels, 20 tracks, multiple powering methods, and support for multiple
USB control surfaces, the 888 can be easily tailored to your workow. An updated processing architecture and multiple FPGAs enables the 888 to
be fully routable: any physical input may be sent to any track, bus, or output.
Many features have carried over from the premium Sound Devices’ Scorpio, such as the new 8-Series preamplier design, 2 SD card slots, internal
256 GB SSD, and dual L-Mount battery charging and powering. Alternatively, power your 888 using a smart battery, NP-1 battery, or an in-line power
supply via its TA4 DC input. The ultra-accurate, fully-featured timecode generator contains its own battery to hold timecode for up to four hours after
power off.
Dedicated coms and slate allows for professional bi-directional communication with other crew members. Send customized mixes to the camera
or crew with multiple mix buses. With the ability to record to three media simultaneously, you can turn over an SD card to production, AAC les for
transcription, and keep a backup on the internal 256 GB SSD.
A built-in three band EQ may be set to either pre- or post-fade for each channel to tackle any problems directly on-set. Enable Dugan Automixing or
MixAssist to automatically attenuate unused microphones in multi-microphone applications. Up to 16 channels can be automixed at a time.
Get the perfect t on your cart with one of several supported USB control surfaces for remote fader and transport control. Download the companion
Android app, SD-Remote, to access to transport controls, metering, and sound reports on a large touch screen.
We are honored to be part of your kit.
Sincerely,
Sound Devices
