ATI Technologies M100 Kullanım ve Bakım Kılavuzu

can make taking off the cover with the AC line still connected into a very exciting

adventure.

Different types of attachment plugs or line cords may be required for connection to

alternate supply voltage.

INSTALLATION

MOUNTING

The M100 can mount to any flat surface with the included angle brackets, which should

be mounted to opposite small faces if the M100 by the cover screws. The M100 can be

rack mounted either singly or in pairs in only1 ¾" using accessory Front Panel Kit,

P/N20273-501.

GROUNDING

The M100 includes an output transformer, beaded, bypassed and clipped input network, a

triple protected AC input, and a double ground plane PC boarded and a will shielded

magnetic enclosure. However, in a difficult broadcast application, RF levels may require

a better ground path for the RF bypass networks than can be provided by the third wire

AC ground and a separate studio inductance ground bus tied to the chassis may be

necessary low inductance studio ground bus tied to the chassis may be necessary.

The power line ground could cause a loop with a separate studio ground. If you are sure

your studio ground will provide adequate protection to your personnel in case pf an

accidental AC short to the chassis, a 3 to 2 adapter can be used to isolate the power line

ground. We strongly recommend that the adapter be removed and the power line ground

be reconnected prior to any service work requiring removal of the studio ground from the

chassis.

INOUT AND OUTPUT CABLES

The female XLR type input connector is wired conventionally with pin 2 HI and pin 1

and the connector housing grounded. +48 VDC Phantom power is applied to both pins 2

and 3 with reference to ground on pin 1.

The male XLR type output cable connector is wired with pin 2 HI, pin 3 LO and pin 1

floating. The connector housing is grounded to the chassis. Pin 1os a left ungrounded to

prevent large loop currents from circulating through the cable shield if inadvertently

grounded at both ends. The shield should be grounded at the receiving end of the signal.

If absolutely necessary to ground pin 1, grounded lift jumper W4 can be inserted into the

circuit board.
