User manual YAMAHA CBX-D3

[. . . ] SPECIAL MESSAGE SECTION This product utilizes batteries or an external power supply (adapter). DO NOT connect this product to any power supply or adapter other than one described in the manual, on the name plate, or specifically recommended by Yamaha. WARNING: Do not place this product in a position where anyone could walk on, trip over, or roll anything over power or connecting cords of any kind. The use of an extension cord is not recommended! [. . . ] Solid RED indicates that the CBX-D3 is recording to disk. Flashing RED indicates an error condition. 5 MIDI indicator Green LED. Lights up when the CBX-D3 receives a supported system-exclusive message. Front panel7 Front panel 7 6 SAMPLING FREQ indicators Indicate the sampling frequency selected for recording or playback: 48kHz, 44. 1kHz, 32kHz, or 22. 05kHz. The frequency selection is made by software. The 48kHz LED also acts as a download indicator, flashing to indicate that the CBX-D3 has not yet completed power-on downloading of system data. 7 INPUT LEVEL indicators Two 3-segment LED bargraphs indicating the audio input levels. You can adjust the input levels by turning the INPUT LEVEL control dials. NOTE: The top LED in each of the bargraphs is the "CLIP" LED. While peak indicators on analog equipment tend to light up approximately 3 ~ 6dB below the signal clipping level, CLIP LEDs on digital equipment come on only if clipping has actually occurred. Since digital-audio signal clipping produces unpleasant distortion, pops, and clicks, you DO NOT want the CLIP LEDs to come on. 8 OUTPUT MONITOR indicators Four variable-brightness LEDs. Each LED indicates the output level of the corresponding channel. The LED gets gradually brighter as the level rises. 9 INPUT LEVEL controls Independent level controls for analog input channels 1 and 2. You can also use these controls to balance the left and right channels of a stereo source connected to the analog inputs. Note that the input level automatically changes to accommodate microphone or line input. 0 MIC 1 & 2 Two 1/4-inch jacks for direct input of microphone analog audio signals. These are unbalanced inputs with nominal input levels of ­60dBm. Plugging a microphone into either of these jacks automatically switches the channel's nominal input level from line (­20dBm) to microphone (­60dBm). Note that connecting a cable to a MIC jack automatically disables any line input connected to the corresponding ANALOG IN jack on the near panel. NEVER plug a line input into a MIC jack. Always set the INPUT LEVEL to minimum before inserting or removing a microphone or line input. 8 8 Chapter 4 : Controls & Connections Chapter 4 : Controls & Connections Rear panel 2 3 4 9 OUT IN 2 IN 1 OUT 4 OUT 3 OUT 2 OUT 1 IN OUT SCSI ID 5 DC IN ANALOG IN/OUT MIDI DIGITAL SCSI 1 5 6 7 8 NOTE: For your convenience, the top panel includes illustrations and names of all terminals located on the rear panel. This may help you locate cables and connectors without having to look behind the device. 1 DC IN connector Power connector. Connect one end of the supplied power-adaptor cord to this connector, then insert the plug end of the cord into an appropriate AC receptacle. 2 Cable clip Wrap the adaptor cord around this clip to help prevent accidental disconnection. 3 ANALOG IN 1&2 Two 1/4-inch phone jacks for direct input of analog audio signals. These are unbalanced inputs with nominal input levels of ­20dBm, and can be connected to the outputs of a mixer, synthesizer, drum machine, or other such device. Note that connecting a cable to the MIC jack on the front panel automatically disables the corresponding ANALOG IN jack. If cables are connected to both MIC and ANALOG IN, only the MIC (nominal ­60dBm) signals will be received. NOTE: Always set the INPUT LEVEL to minimum before inserting or removing a microphone or line input. 4 ANALOG OUT 1~4 Four 1/4-inch phone jacks that output audio data in analog form. [. . . ] The CBX-D3 OUTPUT MONITOR indicators show a signal, but nothing is output. Output suddenly stops during playback of a stereo sound file. Check the analog and digital connections. Make sure that the application software's recording monitor function is set off for each channel. [. . . ]
