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 6410N (see section 3.2)
The 6420N (see section 3.3)
Recommendations for achieving the best performance (see section 3.4)

3.2 About the 6410N
The 6410N is a high performance format converter for digital audio signals. It
converts AES/EBU, AES-ID3, S/PDIF or Toslink® optical digital audio
signals simultaneously
1
to:
Analog balanced stereo on detachable terminal block connectors
Unbalanced stereo on a 3.5” jack, capable of driving a 32load
(headphones)
In particular, the 6410N:
Supports multi-standards - AES/EBU, IEC 958, S/PDIF and EIAJ
CP340/1201 professional and consumer formats with sampling
frequencies up to 96kHz
Provides automatic equalization and reclocking of the digital audio stream
coming from any digital input
Automatically detects the sample rate of the digital input, ranging from
32kHz to 96kHz
Features selectable conversion ratio (D/A) settings: 0dBFS to +12dB,
+16dB, +20dB or +24dB
Has an S/N Ratio of over 88dB
Has AES/EBU and AES-ID3 transformer coupled inputs
The 6410N is 12VDC fed and is housed in a DigiTOOLS enclosure.

3.3 About the 6420N
The 6420N is a high performance format converter for balanced audio
signals. It converts two channels of balanced audio signals to AES/EBU,
AES-ID3, S/PDIF and TOSlink® optical digital outputs simultaneously.
In particular, the 6420N:
Supports multi-standards - AES/EBU, IEC 958, S/PDIF and EIAJ
CP340/1201 professional and consumer formats with sampling
frequencies up to 96kHz
With its analog balanced stereo audio input signal, splits to four digital
audio output signals
1
, available in all the possible digital audio interfaces
Features selectable sampling frequencies of 32k, 44.1k, 48k, or 96k
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.
3.4 Recommendations for Achieving the Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise-
levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position your
Kramer 6410N/6420N away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
2
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
