Embodiments include an audio component configured to produce a first audio signal; a removable fader component configured with a first connection point for connectivity to the audio component and a second connection point for connectivity to an external audio component that produces a second audio signal, wherein a hardware component, a software component, or a combination thereof for performing a mixing of the first audio signal and the second audio signal is contained within the removable fader component; and a receptacle integrated into the apparatus, wherein the receptacle is configured to hold the removable fader component to the apparatus. ## Claims ### Claim 1 A system comprising: a record player configured to receive a record and to produce a first audio signal using the record; a removable fader component affixed to and removable from the record player, wherein the removable fader component is configured with a first connection point for connectivity to the record player and a second connection point for connectivity to an external audio component that produces a second audio signal, the removable fader being further configured to mix of the first audio signal and the second audio signal; and a plurality of receptacles integrated with the system, wherein a first one of the plurality of receptacles is configured to hold the removable fader component, and a second one of the plurality of receptacles is configured to interface with an external component and to receive another removable fader. ### Claim 2 (depends on 1) The system according to claim 1, wherein the removable fader component is enclosed within a fader housing that provides access to the first connection point and the second connection point, and wherein the removable fader component is operable as a standalone fader. ### Claim 3 (depends on 2) The system according to claim 2, wherein the receptacle is located on an outer edge of the record player. ### Claim 4 (depends on 2) The system according to claim 2, wherein the removable fader component includes a knob, wherein the removable fader component and/or the knob include one or more features to indicate where the knob and associated source priority between the first audio signal and the second audio signal are in relation to the fader housing. ### Claim 5 (depends on 4) The system according to claim 4, wherein the removable fader component includes a button or switch to change the associated source priority. ### Claim 6 (depends on 1) The system according to claim 1, wherein the plurality of receptacles are along an identical side of the system. ### Claim 7 (depends on 1) The system according to claim 1, wherein a location of the plurality of receptacles vertically aligns the removable fader component and a knob of the removable fader component with one or more audio controls of the record player. ### Claim 8 (depends on 1) The system according to claim 1, wherein the first one of the plurality of receptacles is movable relative to the record player to enable the removable fader component to be held in more than one location relative to the record player. ### Claim 9 (depends on 8) The system according to claim 8, wherein each of the more than one location vertically aligns the removable fader component and a knob of the removable fader component with one or more audio controls of the record player. ### Claim 10 (depends on 1) The system according to claim 1, wherein the first connection point and the second connection point include an analog connection, a digital connection, an external audio component, or a combination thereof. ### Claim 11 (depends on 10) The system according to claim 10, wherein the record player includes a separate hardware component, software component, or combination thereof for connecting the record player to the external audio component by the analog connection, the digital connection, or the combination thereof. ### Claim 12 (depends on 10) The system according to claim 10, wherein the analog connection, the digital connection, or the combination thereof is a proprietary design. ### Claim 13 (depends on 10) The system according to claim 10, wherein the digital connection is a Universal Serial Bus (USB) connection. ### Claim 14 (depends on 10) The system according to claim 10, wherein the digital connection between the removable fader component and the external audio component is a short-range wireless connection. ### Claim 15 (depends on 14) The system according to claim 14, wherein the removable fader component is connected to the external audio component by the short-range wireless connection, the external audio component includes a smartphone, a laptop computer, a tablet computer, a wireless speaker, or any device capable of transmitting one or more digital files via the short-range wireless connection. ### Claim 16 (depends on 1) The system according to claim 1, wherein the hardware component, the software component, or the combination thereof provides for a user customization of the first connection point, the second connection point, or a combination thereof to facilitate connectivity of the removable fader component to the record player, the external audio component, or a combination thereof. ### Claim 17 (depends on 1) The system according to claim 1, wherein the hardware component, software component, or a combination thereof provides for a user customization of one or more performance characteristics of the removable fader component. ### Claim 18 (depends on 16) The system according to claim 16, wherein the user customization is available while the removable fader is held by the first one of the plurality of receptacles or removed from the system. ### Claim 19 (depends on 1) The system according to claim 1, wherein the record player, the external audio component, or a combination thereof includes a record player, a digital disc jockey (DDJ) device, a compact disc player, a digital media player, a smartphone, a tablet computer, a laptop computer, a drumbeat machine, a piano keyboard, recording software, a touch screen, or a wireless speaker. ### Claim 20 (depends on 1) The system according to claim 1, further comprising: a non-removable fader being integrated with the system for controlling level of the first audio signal from the record player.
