5. Setup
5.1 Placement
Position your monitors to form an equilateral triangle with your listening position. Ensure they are at ear level and angled towards you for optimal stereo imaging. Avoid placing them directly against walls if possible, or use acoustic treatment to manage bass response.
5.2 Connections
The Diamond Studio 7BT offers versatile input options:
- XLR Input: For balanced audio connections from professional audio interfaces or mixers.
- TRS Jack Input: For balanced or unbalanced audio connections using a 6.3mm (1/4-inch) TRS or TS cable.
- RCA Input: For unbalanced audio connections from consumer-grade audio equipment.
- Bluetooth: For wireless audio streaming from compatible devices.
Connect your audio source to the desired input on the rear panel of the monitor. If using a stereo pair, connect each monitor to the left and right outputs of your audio source.
5.3 Power Connection
After making all audio connections, connect the supplied power cable to the AC input on the rear of the monitor and then to a suitable power outlet. The monitor supports AC power options from 100V to 240V.
6. Operating
6.1 Power On/Off
Locate the power switch on the rear panel of the monitor. Flip the switch to the 'ON' position to power on the unit. The power indicator LED (green/white LOGO) will illuminate. Flip to 'OFF' to power down.
6.2 Volume Control
Adjust the system volume using the dedicated control on the monitor. Start with a low volume setting and gradually increase it to a comfortable listening level.
6.3 Equalization (EQ) Adjustment
The monitor features HF/LF level adjustment controls to fine-tune the frequency response to your listening environment. These controls allow for adjustments of -2, 0, +1, or +2 dB for both high and low frequencies. Experiment with these settings to achieve the desired tonal balance.
6.4 Bluetooth Pairing and TWS
To connect via Bluetooth:
- Ensure the monitor is powered on and in Bluetooth pairing mode (refer to the monitor's specific Bluetooth indicator, if any).
- On your compatible device (smartphone, tablet), enable Bluetooth and search for available devices.
- Select 'Diamond Studio 7BT' from the list of devices to pair.
True Wireless Stereo (TWS): The Diamond Studio 7BT supports TWS technology, allowing two monitors to be linked wirelessly to create a stereo pair from a single Bluetooth input. Follow the specific instructions provided with your monitors for TWS pairing, typically involving a sequence of button presses on both units to establish the stereo link.
7. Maintenance
To ensure the longevity and optimal performance of your Diamond Studio 7BT monitors:
- Cleaning: Use a soft, dry cloth to clean the exterior of the monitor. Do not use abrasive cleaners, waxes, or solvents.
