3. Setup Guide
3.1 Unpacking
Carefully remove the monitor from its packaging. Ensure all components are present:
- Tannoy Reveal 402 Studio Monitor (1 unit)
- Mini jack cable
- Power cable
3.2 Placement
For optimal sound, place the monitors on a stable, flat surface, such as a desktop or speaker stands. Ensure they are positioned to form an equilateral triangle with your listening position. The front-firing bass port allows for more flexible placement closer to walls if necessary, but experimentation is recommended for the best acoustic results.
3.3 Connections
- Power Connection: Connect the supplied power cable to the monitor's power input and then to a suitable AC power outlet (100V).
- Audio Input:
- For a single monitor setup or linking two monitors: Use the included mini jack cable to connect your audio source (smartphone, tablet, MP3 player) to the 1/4" TRS Aux Input on the monitor.
- To link two monitors for stereo sound: Connect the mini jack cable from your audio source to the Aux Input of one monitor. Then, use another mini jack cable (not included, or use the provided one if only one monitor is used) to connect the "Monitor Link" output of the first monitor to the "Monitor Link" input of the second monitor. This creates an instant stereo setup.
- Alternatively, use the balanced XLR or 1/4" TRS inputs for professional audio interfaces.

4. Operating Instructions
4.1 Power On/Off
Once connected, locate the power switch on the rear panel of the monitor. Flip the switch to the 'ON' position to power on the unit. The Tannoy logo on the front will illuminate. To power off, flip the switch to the 'OFF' position.
4.2 Volume Control
Adjust the volume using the gain control knob on the rear panel. Start with a low volume and gradually increase it to a comfortable listening level. For precise mixing, it is recommended to set the monitor volume to a consistent level and control the overall output from your audio source or interface.
4.3 EQ Adjustment (if applicable)
The Reveal 402 is designed for a flat frequency response. However, if your listening environment requires minor adjustments, refer to the rear panel for any available EQ controls (e.g., High Frequency Trim, Bass Adjust) and adjust them according to your acoustic space and preference. These controls help compensate for room acoustics and ensure accurate monitoring.
5. Maintenance and Care

- Dust Protection: Keep the monitor free from dust. Consider using a dust cover when not in use for extended periods.
- Ventilation: Ensure proper ventilation around the monitor. Do not block the front-firing bass port or any rear vents.
