1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront video, audio, presentation, and broadcasting professionals on a daily basis.
2 Getting Started We recommend that you: Unpack the equipment carefully and save the original box and packaging materials for possible future shipment Review the contents of this user manual i 2.1 Go to http://www.kramerelectronics.com/support/product_downloads.asp to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.2 Safety Instructions ! 2.3 Caution: There are no operator serviceable parts inside the unit Warning: Use only the Kramer Electronics input power wall adapter that is provided with the unit Warning: Disconnect the power and unplug the unit from the wall before installing Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled.
3 Overview Both the 6410N Digital to Analog Audio Converter and the 6420N Analog to Digital Audio Converter use digital audio transmission standards, as Section 3.1 describes. This section summarizes the: 3.1 Digital and audio outputs on the 6410N and 6420N (see Section 3.1) 6410N (see Section 3.2) 6420N (see Section 3.
Analog balanced stereo on detachable terminal block connectors Unbalanced stereo on a 3.
Features selectable gain ratio (A/D) settings: -12dB, -16dB, -20dB or -24dB to 0dBFs Features selectable digital audio system bits (professional or consumer) Has AES/EBU and AES-ID3 transformer coupled outputs The 6420N is 12VDC fed and is housed in a DigiTOOLS enclosure.
4 Your Audio Converters Section 4.1 defines the 6410N Digital to Analog Audio Converter and Section 4.2 defines the 6420N Analog to Digital Audio Converter. 4.
4.1.1 Selecting the Input To select the input on the 6410N use the following: 4.1.2 Press A and Press B to select: IN IN AES/EBU OUT IN AES 75 IN OUT S/PDIF OUT OUT OPTICAL Setting the 6410N Gain Control Set the gain control using the DIP-switches on the underside of the 6410N as shown in Figure 3.
The following table shows an example of the relation between the input signal, the selected gain and the THD + N. Vinput [vrms] 4.2 Gain [dB] 1 +12 THD + N [dB] @1kHz -94 1 +16 -95 1 +20 -94 0.

5 Using the Audio Converters i Always switch off the power to each device before connecting it to your 6410N, 6420N. After connecting your 6410N, 6420N, connect its power and then switch on the power to each device. Sections 5.1 and 5.2 describe how to connect the 6410N Digital to Analog Audio Converter and the 6420N Analog to Digital Audio Converter, respectively. 5.
3. Connect the 12V DC power adapter to the power socket and connect the adapter to the mains electricity (not shown in Figure 6). 4. Set the conversion ratio on the underside of the unit. It is essential that you choose the correct conversion ratio to prevent clipping, and to maintain the S/N ratio within the spec limits. The selection of the conversion rate greatly depends on the type of audio played, and also on the audio equipment that is connected to the 6410N.
5.2 Connecting the 6420N Analog to Digital Audio Converter To connect your 6420N Analog to Digital Audio Converter, as illustrated in the example in Figure 7, do the following: 1. Connect an analog balanced stereo source (for example, a balanced audio tape player) to the ANALOG INPUT LEFT and RIGHT detachable terminal block connector connectors via shielded twisted pair cables. 2.
