SAM1-3GM and SAM1 MADI Combined User Handbook Version One Issue 1
Amplitude: 800mV p-p ±10%
AES
Four AES (8 channels) may be output from analogue audio, embedded audio.
Connector type: 25way D-type 4 AES pairs (In and Out), pin-out as per Yamaha Standard
Impedance: 75 unbalanced or 110 balanced. Impedance is switch selected with
on-board transformer balancing. To obtain an unbalanced connection one line of the output needs
to be grounded at an electrically convenient point.
Amplitude: 1V into 75 or >2V into 110
Analogue Audio
Eight analogue channels (4 stereo pairs) that may be output from AES, embedded audio or from
decoded Dolby E/D when the option is fitted
Connector Type: XLR one pair fixed or variable
25 way D type 4 stereo pairs, pin-out as per Yamaha/Tascam
Format: Electronically balanced, centre ground.
D/A Conversion: 24 bit resolution.
THD+N: >80dB referred to 0dBFS
Loudspeakers
Connector Type: 0.156” board header
Format: Two active cross-over or 4 broad-band loudspeaker outputs
10 to 40W (4) per channel into depending on input power supply
GPI inputs

Control
Connector type: Header for current AMU-1 operator control board
Connector type: Header, serial bus for future operator control/display panels
8.0 Installed HDI-4 MADI card
Overview
The HDI-4 MADI module has been especially designed for use with the HDC-2 audio monitor
module and provides bi-directional interconnectivity between the two devices.
HDI-4 supports the AES10 Multichannel Audio Digital Interface format defined in 1991 by the Audio
Engineering Society and updated to AES10-2003 twelve years later .
Coaxial Input
75R BNC supporting 56 / 64 channel MADI at 48kHz
Fibre Input
Single Mode SC format connection supporting 56 / 64 channel MADI at 48kHz
Coaxial Output Loop and Reclocked
75R BNC supporting 56 / 64 channel MADI at 48kHz up to 200 metres (factory tested using cable
clone) depending on cable and connector quality
Fibre Output
Single Mode SC format connection supporting 56 / 64 channel MADI at 48kHz.
Wavelength defined as 1300nm, maximum transmission length guaranteed to 2km.
