Frequently Asked Questions - MBT Rupert Neve Designs

What is the MBT Master Bus Transformer?

The MBT is a Master Bus Transformer from Rupert Neve Designs. It combines a shelving EQ, an opto compressor, a stereo field width processor, and a SILK harmonic section in a single 1U rack unit. It is designed for mix bus and individual source processing.

How do I bypass the MBT?

Press the BYPASS ALL switch on the front panel. It illuminates RED when engaged, providing a true hard-wire bypass that passes audio even if power is lost.

What are the SILK controls?

SILK adds transformer harmonics. The BLUE control emphasizes low frequencies, RED emphasizes high frequencies, and HARMONICS adjusts the overall harmonic content. The DRIVE LED indicates optimal signal level for harmonics.

What is the compressor ratio?

The compressor offers two ratios: LO (2:1) and HI (5:1), selectable via the RATIO push-button switch.

How do I connect power?

Use the standard IEC power inlet on the rear panel. The unit accepts 100-240 VAC, 50/60 Hz and consumes up to 35 Watts. The rocker switch on the rear controls power.

What is the BLEND control?

The BLEND control mixes the dry (uncompressed) signal and wet (compressed) signal. At 0% you hear only the input; at 100% you hear only the compressed signal.

How do I use the Width processor?

Engage the WIDTH IN switch (illuminates green). Use WIDTH HPF to set the high-pass filter frequency (50-800 Hz) for the width processing, and WIDTH control to adjust stereo field width from minimum to maximum.

What is ZENER DRIVE?

ZENER DRIVE engages a soft-clip circuit that adds saturation and gentle distortion. Press the switch to enable it; it illuminates AMBER when active.

How do I clean the MBT?

Clean the unit with a dry cloth only. Do not use any liquids or sprays.

What is the warranty period?

The MBT comes with a 3-year limited warranty from Rupert Neve Designs covering defects in materials and workmanship. Proof of purchase is required.

Operations Manual

Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3.Heed all warnings.

1. Follow all instructions.

2. Do not use this apparatus near water.

3. Clean only with a dry cloth.

4. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.

5. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

6. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized 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.

7. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

8. Only use attachments/accessories specified by the manufacturer.

9. Use only with a 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.

10. Unplug this apparatus during lightning storms or when unused for long periods of time.

1. 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 have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

2. This apparatus shall not be exposed to dripping or splashing, and no object filled with liquids, such as vases or beer glasses, shall be placed on the apparatus.

3. Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.

4. This apparatus has been designed with Class-I construction and must be connected to a mains socket outlet with a protective earthing connection (the third grounding prong).

5. This apparatus has been equipped with a rocker-style AC mains power switch. This switch is located on the rear panel and should remain readily accessible to the user.

6. The MAINS plug or an appliance coupler is used as the disconnect device, so the disconnect device shall remain readily operable.

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure, that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

This symbol indicates that this product must not be disposed of with other waste. Instead, it is your responsibility to dispose of your waste equipment by handing it over to a designated collection point for the recycling of waste electrical and electronic equipment. The separate collection and recycling of your waste equipment at the time of disposal will help conserve natural resources and ensure that it is recycled in a manner that protects human health and the environment. For more information about where you can drop off your waste equipment for recycling, please contact your local city recycling office or the dealer from whom you purchased the product.

1. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

2. Reorient or relocate the receiving antenna.

3. Increase the separation between the equipment and the receiver.
4. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
5. Consult the dealer or an experienced radio/TV technician for help.

CAUTION: Changes or modifications to this device not expressly approved by Rupert Neve Designs LLC, could void the user's authority to operate the equipment under FCC rules.

1. This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications.

1. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in the following chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here:

Duration, per day in hours	Sound Level dBA, Slow Response	Typical Example
8	90	Duo in small club
6	92
4	95	Subway Train
3	97
2	100	Typical music via head phones
1.5	102
1	105	Siren at 10 m distance
0.5	110
0.25 or less	115	Loudest parts at a rock concert

WARNING — To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
