IMPORTANT SAFETY WARNINGS

THIS APPARATUS MUST BE EARTHED. Under no circumstances should the safety earth be disconnected from the mains lead.
The mains supply disconnect device is the mains plug. It must remain accessible so as to be readily operable when the apparatus is in use. If any part of the mains cord set is damaged, the complete cord set should be replaced. The following information is for reference only.

The wires in the mains lead are coloured in accordance with the following code:
Earth (Ground): Green and Yellow (US – Green/Yellow)
Neutral: Blue (US – White)
Live (Hot): Brown (US – Black)

As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured Green and Yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth symbol .
The wire which is coloured Blue must be connected to the terminal in the plug which is marked with the letter N.
The wire which is coloured Brown must be connected to the terminal in the plug which is marked with the letter L.
Ensure that these colour codes are followed carefully in the event of the plug being changed. This unit is capable of operating over a range of mains voltages as marked on the rear panel. The internal power supply unit contains no user serviceable parts. Refer all servicing to a qualified service engineer, through the appropriate Soundcraft dealer.

ELECTROSTATIC DISCHARGE (ESD)

Many semiconductor components are sensitive to electrostatic discharge (ESD). The lifespan of assemblies contain ing such components can be drastically reduced by improper handling during maintenance and repair. Please observe the following rules when handling ESD sensitive components:

• ESD sensitive components should only be stored and transported in the packing material specifically provided for this purpose.
• When performing a repair by replacing complete assemblies, the removed assembly must be sent back to the supplier in the same packing material in which the replacement assembly was shipped. If this should not be the case, any claim for a possible refund will be null and void.
• Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g. area for field service, repair or service bench) and only be touched by persons wearing a wrist band connected to the ground potential of the repair or service bench by a series resistor. The equipment to be repaired or serviced as well as all tools and electrically semi-conducting work, storage, and floor mats should also be connected to this ground potential.
• The terminals of ESD sensitive components must not come in uncontrolled contact with electro statically chargeable or metallic surfaces that would result in a puncture voltage and a discharge shock hazard.
• To prevent the components from undefined transient stress and possible damage due to inadmissible voltages or compensation currents, electrical connections should only be established or separated when the equipment is switched off and after any capacitor charges have decayed.

IMPORTANT SAFETY INSTRUCTIONS

• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with a dry cloth.
• Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
• Do not defeat the safety purpose of a polarised or grounding type plug. A polarised plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
• Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles and the point where they exit from the apparatus.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

NOTE: It is recommended that all maintenance and service on the product should be carried out by Soundcraft or its authorised agents. Soundcraft cannot accept any liability whatsoever for any loss or damage caused by service, maintenance or repair by unauthorised personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. Do not expose the apparatus to dripping or splashing and do not place objects filled with liquids, such as vases, on the apparatus. No naked flame sources, such as lighted candles, should be placed on the apparatus.
Ventilation should not be impeded by covering the ventilation openings with items such as newspapers, table cloths, curtains etc.

WORKING SAFELY WITH SOUND

Although your new unit will not make any noise until you feed it signals, it has the capability to produce sounds which when monitored through a PA system or headphones can damage hearing over time.
The table below is taken from the US Department of Labor directive on occupational noise exposure (1926.52):

PERMISSIBLE NOISE EXPOSURE

Conforming to this directive will minimise the risk of hearing damage caused by long listening periods. A simple rule to follow is — the longer you listen, the lower the average volume should be. Please take care when working with your audio. If you are manipulating controls which you don’t understand (which we all do when we are learning), make sure your monitors are turned down.
Most importantly — don’t be afraid to experiment to find out how each parameter affects the sound — this will extend your creativity and help you to get the best results.
Recommended headphone impedance is 50-600 ohms.

FEATURES
The Mini Stagebox 32i is ideal for for expanding the I/O capabilities of any of the Vi or Si range of Soundcraft consoles regardless of whether that I/O is needed locally or at a distance. The Soundcraft Mini Stagebox 32i requires only 3U of rack space, and in this tiny footprint, provides 32 recallable mic/line inputs and 12 balanced line outputs, all lifted directly from the Soundcraft console family. The Mini Stagebox 32i is connected to a host console using a CAT5 cable and RJ45 connectors. Using two cables to a single console offers redundant MADI capability when the mode switch is set to “RED”. Audio can be supplied to two different consoles by using the Main and Aux connections simultaneously. In this instance, one console should be nominated to have control of the Mic input gains and phantom power. Set the switch to Main or Aux according to which console you have selected to have control. The efficient design of the Mini Stagebox 32i negates the need for a fan making it ideal for applications where silent operation is critical.

MOUNTING MINI STAGEBOX 32i
When installed in a 19″ rack mount ensure all four mounting holes are used. If mounted with other equipment that may get hot it is recommended to leave a 1U gap between the equipment.  In all scenarios, the air vents must not be obstructed. The Mini Stagebox 32i must not be mounted in a fully sealed enclosure.

MADI LINK CONNECTIONS
The Mini Stagebox 32i RJ45 connections provide digital audio and control connections to the console through Cat-5 MADI links. The corresponding MADI card connections in Soundcraft consoles transmit the clock for the Mini Stagebox 32i through the MADI stream. Each card on Si Consoles can only control a single Mini Stagebox mic pre’s functionality. The second (AUX) connector can be used to provide a redundant connection to the console, or to connect to a second console. The MAIN/AUX switch changes the mode of the mic preamp control and redundancy setting.

• When the switch is set to “MAIN”, the console connected to the MAIN port will have the mic preamp control.
• When the the switch is set to “AUX” the console connected to the AUX port will have the mic preamp control.
• When the switch is set to “REDUNDANT” the console will operate in REDUNDANT mode.

The MADI mode light indicates its clock status with the ‘LOCK’ LED. It is possible to connect two different consoles to the MAIN and AUX ports, and provide a split of the mic inputs to the two consoles. However, be aware of which console has control of the preamp gains and is able to send signals to the Mini Stagebox 32i outputs. The main console is determined by the Main/Aux/Redundant switch.
