ASP880 | Contents Welcome & Thank You Thank you for purchasing this audient product! ASP880 can be seen as the natural progression of our classic ASP008 eight channel microphone preamplifier. Using the same proven discrete class-a 8-transistor input stage with extended bandwidth and a noise floor close to the theoretical Johnson noise limit, ASP880 provides a world-class recording front end in a convenient 1RU package.
Box Contents In your ASP880 packaging you should find the following items: • • • ASP880 Mains IEC Cable (in rear protection tube) Quick Start Guide Please visit: www.audient.com/products/asp880/ downloads to get the latest version of the quick start guide and this manual. Watch/ listen to our example video content and grab useful things like a session recall sheet etc.

Safety Information Safety Instructions Important Safety Instructions Important Safety Instructions Please read all of these instructions and save them for later reference before connecting the mains IEC power cable and powering up ASP880. To prevent electrical shock and fire hazard follow all instructions on the rear of the ASP880. 1. 2. 3. 4. 5. 6. 7.
Declaration of Conformities We, Audient Ltd, declare that the product, the ASP880, to which this declaration relates, is in material conformity with the appropriate CE standards and directives for an audio product designed for consumer use. Audient Ltd has conformed where applicable,to the European Union’s Directive 2002/95/EC on Restrictions of Hazardous Substances (RoHS) as well as the following sections of California law which refer to RoHS, namely sections 25214.
Hardware Features Microphone Preamplifiers & Line Inputs Discrete JFET D.I (Instrument) Inputs ASP880 features eight impeccably optimised class-a micprohone preamplifiers. ASP880 features two discrete class-a JFET D.I inputs (Channels 1 & 2). Plugging into these jacks will automatically select the D.I signal over the signals present at tha rear. Featuring a discrete 8-transistor front end, the mic pre is optimised for 0 to 60dB gain with an EIN (equivalent input noise) of -127.5 dB.
Hardware Features Setting Levels & Gain ASP880 has plenty of analogue headroom, running internally on +/-18V DC rails. Aim for -10dB FS peaks on the loudest s when setting ections gain & record ing levels in th e DAW! The unit can deliver up to +27.5dBu at the analogue output DB25 on the rear of the unit. 2. 3. 4. 5.
Hardware Features Variable Input Impedance One stand-out feature of the ASP880 is the variable input impedance (Z) control. There are three impedance load settings on the unit, and these can be used to extract various voicings from your mic collection by loading the mic’s output stage differently. Notably mics with transformer outputs such as SM57 / SM7 dynamic mics or Coles 4038 ribbon microphones often provide quite noticeable changes in tone when operated into various loads.
Hardware Features Analogue Line Outputs Digital Outputs - AES - S/PDIF ASP880 features 8 analogue, cross-coupled line driver outputs on DB25. These fully balanced outputs use the same circuitry as our proven ASP8024 flagship console and provide “transformer-like” differential line drive and high headroom with a sturdy, transparent pair of operational amplfiiers. The on-board digital card in ASP880 can provide both double speed (96kHz) AES and ADAT output signals. 1.
Hardware Features Clocking with the ASP880 Slave Clock Operation - EXTERNAL There are two ways to integrate ASP880 into your system digitally: You may have a studio master clock source such that all digital devices synchronise to your session sample rate, or perhaps you would like the ASP880 to follow your DAW/ recorder session sample rate so that you do not have to reconfigure the unit when you flip between sessions at different sample rates.
ASP880 Block Diagram Troubleshooting & FAQ Troubleshooting FAQs • For more information and service information / support, please search our online Knowledge Base which can be found here: www.audient.com/support My microphones are not producing signal? Double check that phantom power is turned on via the front panel switch, try swapping XLR cables, then double check all connections to the recorder.
