The Sony BCDWZ1 DWZ Series battery charger can use with DWZ-M70 or DWZ-B70HL package systems. Supports use of rechargeable AA NiMH batteries.
Superb Digital Sound Quality
High-quality 24-bit linear PCM digital transmission offers a pristine audio experience and a wide frequency range of 10 Hz to 22 kHz. The audio performance degradation that's typical of conventional analog wireless systems can be avoided, because DWZ is designed without the need for audio companding.
Interuptions in reception (signal drop-out) can be a problem with wireless microphone transmission systems. With the DWZ series; however, this can be reduced to a minimum. Utilizing a space diversity reception system, the DWZ series achieves stable transmission by using dual-antenna inputs/reception circuits. These receive signal over two different paths and automatically select the stronger RF signal for output.
Flexible Audio Outputs
Each DWZ series system receiver includes an XLR balanced output and two 1/4" unbalanced outputs that can be used to output audio to three destinations simultaneously.
Highly Secure Transmission
128-bit standard encryption technology is included to secure transmitted signals and avoid being intercepted by others. By using the encryption feature, users can reduce the worry that confidential information could be intercepted.
Intellegent Feedback Reducer
The Sony intelligent feedback reducer can suppress unwanted feedback (howling) with high-performance DSP and Sony's unique algorithms designed to eliminate feedback before it becomes unbearable. Up to 1024-band suppression filters are continuously tuned automatically in real time, eliminating feedback and avoiding deteriorating the original signal. You can also freely select the audio outputs to which you want this feedback reduction filter to apply - for example, you can output original audio to the main PA system, while processed audio is delivered to your monitor speakers.
Battery Recharging System
All DWZ systems can operate using conventional AA size Alkaline batteries. This system also supports use with NiMH AA size rechargeable batteries along with use of the (optional) BC-DWZ1 battery charger. The BC-DWZ1 is a contactless recharger, this means you simply place the transmitter into the charging station to recharge NiMH-type batteries. You do not need to physically remove the batteries to recharge them, which saves you time and reduces wear and tear to the transmitters.
