Quality, Reliability and Functionality
For Daily Professional Use

The CD-RW900SX is a professional CD recorder and player that replaces the CD-RW900MKII. A slot-loading optical drive ensures years of reliable operation in the most demanding installations. This CD drive allows gapless recording when setting track marks, something not possible using off-the-shelf PC optical drives. A high-performance codec chip is used for A/D and D/A conversion for clean, clear sound quality with a frequency response of 20 Hz to 20 kHz ±0.8 dB. Various recording features like automatic track creation help the operator create polished recordings without constant supervision.

The CD-RW900SX has unbalanced analogue input/output jacks as well as optical and coaxial digital audio connectors. Both the left and right analogue inputs have their own gain controls on the front panel. In addition, the digital input can be controlled for optimal recording levels from a digital source. Functions including auto-cue, auto-ready, pitch control, power-on playback, and fade-in/fade-out playback are provided. It is also possible to control the transport via an optional computer keyboard.

Whether used for PA/rental or fixed installations, the CD-RW900SX is the right choice for reliable CD recording and playback.


Slot-loading CD Drive With Gapless Continuous Recording

The Tascam CD-RW900SX has a slot-loading CD drive

The new CD transport is not simply a repackaged computer drive. Instead, it is designed specifically for audio and uses sophisticated firmware that allows track marks to be written into the audio without audible gaps.

This is perfect for seamless, continuous live recording.

Multiple Ways To Create New Audio Tracks During Recording

The CD-RW900SX offers four options for creating new audio tracks during a recording session including three auto functions:

  • Digital Direct (DD)
    When recording digitally from MC or CD, this function detects track boundaries and divides the recording at these points.
  • Based on input level
    This function creates a track mark based on the input level and starts a new track when the input level drops below a certain value (from –24 dB to –72 dB).
  • Based on time
    Time-based track division can be done every 1–10 minutes. This method is preferred for some applications, such as conference recordings, or when there are no gaps between segments, such as music recordings.

You can also start with a new track manually by pressing the RECORD button during audio recording.

Individual input level controls on the Tascam CD-RW900SX

Professional users will appreciate that the left and right channels of the analogue input have their own input level controls on the front panel. This makes it easy to compensate for different sound levels at a venue already during recording.

In addition, the level on the digital input can be adjusted to achieve an optimal recording level even with a digital source.

Unbalanced analog and SPDIF coaxial and optical connections are provided for connection flexibility.

The Tascam CD-RW900SX offers RCA analogue inputs as well as SPDIF coaxial and optical digital inputs
Play, Pause, Record, Stop, Skip and other functions can be controlled using a PC keyboard.

The CD-RW900SX has a keyboard connector on the front panel that allows a standard computer keyboard to be used for transport control. Use the function buttons to start, pause and stop recording or playback, skip tracks, or switch pitch-control and other functions on and off. You can place the keyboard on a table and operate the CD-RW900SX comfortably, even if it is installed in a 19-inch rack.

Moreover, using an optional keyboard considerably simplifies the input of text, e.g. for track titles and artist names.

Note: A computer keyboard is not included. You can connect any standard PC keyboard with a PS/2 connector.
Anti-shock memory ensures smooth playback in virtually any situation.

As a true professional CD recorder/player, the CD-RW900SX offers a host of playback features for virtually any situation. You can change the playback speed and key individually or together, which can be very useful in a gym or music school, for example. Features such as Auto-Cue and Auto-Ready are handy when you need to play tracks at precise times, such as in a theatre. There is also a Power-on Playback function, which can be used to automatically play background music when power is applied. Various repeat functions (single, program, random, A–B) complete the playback feature set.

Last not least, the CD-RW900SX has an anti-shock memory that ensures smooth playback, even if a shock or vibration lasts up to four seconds.
