A3000 Options A3000 Options You can enhance the capability of your A3000 by installing options. The A3000 supports two options: (1) additional memory, and (2) the AIEB1 board (I/O expansion board). Expansion Memory (SIMMs) The A3000 stores all active data in main memory. To play a sample back, you must first load it into main memory. And whenever you record a sample, you must record it into main memory. Samples consume a great deal of memory. The A3000 comes standard with 2 megabytes (2MB) of memory - but this is only sufficient to store about 23 seconds of high-quality monaural sound (at 44.1kHz sampling frequency), or approximately 11.5 seconds of stereo sound. You can increase this capacity by installing additional memory. The A3000 accepts expansion memory in the form of SIMMs (single in-line memory modules). Using SIMMs, you can install up to 128MB of memory onto the A3000. SIMMs can be purchased from almost any computer-supply dealer. Adding memory will allow you to record longer samples, and to work with more samples at the same time. For information about how to install SIMMs, refer to the Appendix. (312) Important • You need to use 72-pin SIMMs with access time of 70ns or less. The SIMM module size may be 4MB, 8MB, 16MB, or 32MB. The A3000 is designed for use with 32-bit SIMMs, but can also accept installation of 36-bit (parity-type) SIMMs. • SIMMs must be installed in pairs: you can install either two SIMMs or four SIMMs. Both modules in a pair must have the same memory capacity. • The A3000 ships with 2MB of sampling memory installed, and is capable of accessing up to 128MB. If you add one pair of 32MB SIMMs, for example, you increase the available sampling memory to a total of (2 + 32×2 =) 66MB. If you install four 32MB SIMMs, however, the sampling memory size becomes 128MB (and the original 2MB are effectively disabled). • For more information about SIMM purchase, refer to your A3000 dealer. 14
