Chapter 2 Initial Preparation

The Model SSM is delivered in a special, protective container and was

carefully inspected both mechanically and electrically before shipment.

It should be physically free of mars and scratches and in perfect

electrical order upon receipt. To confirm this, the product should be

inspected for physical damage that may have occurred in transit. Any

damage should be reported to your dealer and delivery company as

soon as possible.

The Model SSM will operate satisfactorily over a wide range of

ambient temperatures, and the power supply will operate from 10 to 50

degrees C. If the power supply is installed in an equipment rack that

also contains heat producing equipment such as power amplifiers or

other power supplies, adequate ventilation should be provided. This will

prolong component life and maximize operational stability.

While the internal circuitry of the SSM is fully shielded by the steel

chassis, installation should nevertheless be planned to avoid locating the

SSM, optional SSM Expander, or any low level audio equipment

immediately adjacent to power amplifiers, power supplies, or any source

of Electromagnetic emissions.

To protect operating personnel, the National Electrical

Manufacturers Association (NEMA) recommends that the

instrument panel and rack cabinet be grounded. All Speck power

supplies are equipped with a three conductor power cord which, when

plugged into an appropriate receptacle, grounds the power supply. The

offset pin on the power cord's three-prong plug is the ground wire.

The three conductor line cord and plug assembly is wired in

accordance with NEMA convention (line - black, Neutral - white, and

safety earth - green). Audio signal grounds and DC grounds from the

mixer are isolated from the AC safety earth.

When using the Model SSM and its power supply outside North

America, it will be necessary to adapt a different power plug for that

specific country.
