CHAPTER 1: Overview

Introduction
MADI.9648 is a synchronous MADI sample rate converter with four independent SRC blocks for bidirectional conversion of 128 audio channels. Equipped with eight MADI  ports it features synchronous low latency conversion in a ratio of exactly 1:2 or 2:1 to translate between 2 FS (88.2/96 kHz) and 1 FS (44.1/48 kHz)

Feature Summary

to 264 V AC / 47 Hz to 63 Hz / safety class 1)

How it works
A 1 FS MADI stream with 64 audio channels is converted into two 2 FS MADI streams with 32 channels each. Vice versa two 2 FS streams are converted and combined into a single 1 FS stream.
MADI.9648 provides:

• 2 x conversion from 1 FS to 2 FS
• 2 x conversion from 2 FS to 1 FS

No settings are required:

• Fixed signal routing
• Automatic signal detection of frame format (48k/96k Frame) and channel mode (56/64 ch).
• The frame format of 2 FS output is set following the input of the same port
• The output of each SRC block is clocked by its corresponding MADI input

Applications
MADI.9648 enables an easy-to-handle integration of external equipment with most
recent live consoles with 96 kHz processing.
Typical applications include:

• monitoring
• external effects
•  ..

Scheme

The ports underlined are used as a clock (and signal source for 1 FS to 2 FS) once both input ports detect the signal.

CHAPTER 3: Installation

Installing the Device

1. Open the packaging and check that the contents have been delivered complete and undamaged.

2. Fix the device in a 19’’ frame with four screws, or place it on a non-slip horizontal surface.
   WARNING!
   Avoid damage from condensation by waiting for the device to adapt to the environmental temperature. Proper operation can only be guaranteed between temperatures of  5º C and 45º C and a maximum relative humidity of 80%, noncondensing.
   Ensure that the unit has suffi cient air circulation for cooling.

3. Remove the protective cap from the optical MADI port(s) before use. NOTE!
   Retain the protective cap if the optical port is unused. This will protect against soiling which can lead to malfunction.

4. Connect the signal cable(s) for the MADI signals

5. Optional: Connect a USB cable to the USB port for firmware updates.
   This requires the USB Serial driver (Windows) to be installed fi first.

   The left socket is switched by the power supply switch. The right socket will power up the device immediately when connected to the mains.
   WARNING!
   This device must be connected to the mains using the three-cord power leads supplied with the system. Only supply the voltages and signals indicated (84 V – 264 V).

7. Turn on the power switch:
   While the device is booting the currently installed firmware is indicated in the front panel displays – e.g. firmware version 1.1.

8. Check if the latest firmware is installed on the device. It is recommended to use the latest version that is available on the product page at www.directout.eu.

9. Optional: Connect a USB cable to the USB port for firmware updates. This requires the USB Serial driver (Windows®) to be installed first. The driver and the installation instructions are available at www.directout.eu.

TIP!
Keep any packaging in order to protect the device should it need to be dispatched for service.

CHAPTER 4: Operation

Introduction
This chapter describes the basic operation of the device.
Note that throughout this manual, the abbreviation FS refers to sample rate or sample frequency. So, when dealing with scaling factors, the following sample rates can be written as:
• 44.1 kHz or 48 kHz = 1 FS
• 88.2 kHz or 96 kHz = 2 FS
• 176.4 kHz or 192 kHz = 4 FS

Frame Formats at the 2 FS output (ports 1 to 4)**
The 2 FS inputs accept both 96k Frame and 48k Frame (S/MUX). For the frame format of the 2 FS output there are two options:

1. Automatic (default)
   The output frame format follows the input frame format.
   S/MUX => S/MUX or 96k Frame => 96k Frame

2. Force to 96k Frame
   Output frame format is forced to 96kFrame
   S/MUX => 96k Frame or 96k Frame => 96k Frame
   To switch between the two modes please contact support@directout.eu.
