They are on 3-pole a gauge jack sockets, wired as shown on the left and below, . They accept 3-pole 1/4" "A" gauge (TRS) jacks, or 2-pole mono jacks. The jack socket outputs are as follows: FX Insert Send, Main Output Insert Send Left, Main Output Insert Send Right, Stereo 2 Left, Stereo 2 Right, Mono1, Mono2, Booth Left, Booth Right and Sound-to-Light.

Functional Descriptions D-MIX500 Functional Description 4. 1 Stereo Input Channels 1 & 7 - CD/AV Input Stage (1) The input switch selects the Input source. When this switch is pressed AV 1(2) has been selected and the LED to the right of the switch lights up orange. When the switch is released a green LED will illuminate thus meaning the CD 1(2) Input source has been selected. (2) Gain- Adjusts the level of the selected input by +/-10dB, and should be set up carefully to ensure a good signal level to the rest of the mixer. If it is set too high the signal will distort as it overloads the channel and causes clipping. If it is set too low the level of any background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer. Equalisation (3) The Equaliser (EQ) allows precise manipulation of the sound. Three EQ bands are provided, HF (High Frequency), MF (Mid Frequency) and LF (Low Frequency). These EQ bands provide 15dB of cut and boost at 10kHz, 1kHz and 80Hz respectively on the D-MIX500; 5dB cut and boost at these frequencies on the D-MIX500L. Channel Output (4) The Peak LED warns the DJ of excessive signal level in the channel 6dB before clipping occurs. The signal is sampled just after the EQ section, and illumination of the LED will indicate that the input sensitivity is set too high, or that the EQ settings are too extreme. When the switch is set to the on position an LED will illuminate showing the channel is active. (6) The CUE switch enables the pre-fade channel signal to be routed to the DJ's headphones and booth monitors if required. (7) The Output signal level from the channel is set by the Fader. THE OUTPUT OF THESE CHANNELS MAY BE ASSIGNED TO THE CROSS FADER. Channel 7 may be assigned to the right position of the cross fader. 4. 2 D-MIX500 Functional Description Stereo Input Channels 2 & 6 - VINYL/CD Input Stage (1) The input switch selects the Input source. When this switch is pressed CD 4(3) has been selected and the LED to the right of the switch lights up orange. [. . . ] (7) The Main/Music switch is set to Music when the DJ wants to mute the Mic source from the Mono 1 output. When set to Main the music is mixed with the Mic signals from channels 3 and 4. (9) The Main/Music switch is set to Music when the DJ wants to mute the Mic source from the Stereo 2 output. When set to Main the music is mixed with the Mic signals from channels 3 and 4. [. . . ]
