CEDAR Audio have announced the release of the DNS 4, a four-channel dialogue noise suppressor with both analogue and digital connectivity. Offering double the channel count of their DNS 2 unit whilst taking up little more space, the DNS 4 is a light, portable solution which retains the near-zero latency performance of its predecessors, making it suitable for use in a wide range of situations - from location recording and broadcasting to live sound applications in theatres and conference venues, as well as in the studio.
The device has been designed to be incredibly fast and simple to use. The DNS algorithm simply requires users to switch on a Learn function which identifies and adapts to background noise, and then adjust the amount of noise attenuation that they require. Each of the four channels benefit from CEDAR’s state-of-the-art noise suppression, which utilises 40-bit floating-point processing.
The DNS 4 is equipped with four analogue inputs, the first two of which are switchable between microphone and line level, and are presented on XLR connectors located on the left side panel. The microphone inputs feature ultra low-noise preamps and +48V phantom power is available, with the device offering 10mA per input. Line inputs three and four are located on the same panel, but this time via mini-XLR sockets.
The right side panel is populated by a further six mini-XLR sockets, the first two of which provide the four channels of AES3 or AES11 digital inputs. The following four sockets present the device’s analogue line level outputs, with two of them able to be configured to provide the four digital output channels, again in either the AES3 or AES11 formats. The panel also houses a USB socket, and a Hirose HR-10 power input connector.
- Four line-level analogue inputs with >102dB dynamic range
- A/D conversion (internal sync): 24-bit linear PCM at 48kHz
- A/D conversion (external sync): 24-bit linear PCM at 40 - 100 kHz
- Four channels of AES3 (IEC60958) / AES11 (DARS) digital inputs
- Sample rate (external sync): 40kHz - 100kHz
- Four line-level analogue outputs
- Four channels of AES3 (IEC60958) at 48kHz (internal sync) or locked to digital input
The DNS 4 measures 185 x 130 x 45 mm, and weights 750g. The device accepts 8V to 17.5V DC power (nominal 12V), with a maximum power consumption of 15W at 12V. A universal power adapter is supplied, which accepts a 85VAC - 260VAC input and delivers a 12V output.
