Technical Documentation CD- A630 TASCAMs CD- A630 combines the two most popular consumer media formats into one box. The CD player and cassette deck can act as separate components, or take advantage of the combination with direct dubbing, long play capabilities, and an input- saving cascade output mode. RCA audio I/O and a wireless remote are included for basic applications; an optical SPDIF output and parallel remotes and tallies are available for advanced installations. 7733 Telegraph Road Montebello, CA 90640 (323) 726- 0303 All features and specifications are subject to change without notice. Contact your local TASCAM representative for the latest information. The CD- A630 is designed to be affordable, easy to use, and reliable. Mobile Users - Live Production - Rehearsal Halls The dual function, compact design will appeal to anyone who needs to change locations on a regular basis, or who has limited space to fit their gear into. Plus, the ability to cascade the CD and cassette can save inputs on a mixer when you need it most. Lecture Halls - Board Rooms - School PA There are many situations where the person who needs to operate the equipment has little or no official training. The key in this situation is to keep the operation of the unit straight forward. The CD- A630 is ideal for these situations. DJs - Dance Studios - Health Clubs Anyone involved in dance or aerobic workouts knows the value of pitch control. The CD- A630 offers independent pitch control for the CD player and cassette deck. Pitch control can make the difference between having the tempo drag a bit and having the right punch. This is also great for transferring pitch adjusted CDs to tape for later performance where the owners arent fortunate enough to have this.
