- Headphone Output (PHONES): Connect headphones to the 1/4" TRS 'PHONES' jack for monitoring.
- 2-Track Output (2-TR OUT): Use RCA cables to connect a recording device to the '2-TR OUT' ports.

3. Bedien die menger
Understanding the controls is key to effectively using your UB502 mixer.
3.1 Kanaalkontroles
Each input channel (Mic/Line 1, Line 2/3, Line 4/5) features dedicated controls:
- WINS: Adjusts the input sensitivity for the connected device. Use this to achieve a healthy signal level without clipping.
- EQ (gelykmaker): The mono channel (Mic/Line 1) has a 2-band EQ (HIGH and LOW) to shape the tone of the input signal.
- PAN/BAL: The PAN control (mono channel) adjusts the signal's position in the stereo field (left to right). The BAL (balance) control (stereo channels) adjusts the relative level of the left and right signals.
- VLAK: Controls the overall output level of the individual channel to the main mix.
- KLIP LED: Brand wanneer die insetsein te hoog is, wat potensiële vervorming aandui. Verminder die VERSTERKING as hierdie LED gereeld brand.
3.2 Hoofseksie-kontroles
The main section manages the overall output and monitoring:
- HOOFMENGSEL: Beheer die algehele volume van die hoof stereo-uitset.
- FOONE: Verstel die volume vir die koptelefoonuitvoer.
- 2-TR TO MIX: Routes the 2-Track input signal to the main mix.
- 2-TR TO PHONES: Routes the 2-Track input signal to the headphone output for monitoring.
- VLAKMETER: LED indicators display the output level of the main mix, helping to prevent clipping.
