Congratulation on your purchase of a Yamaha NS-IOM STUDIO Monitor Speaker System! The NS-IOM STUDIO has been pain­

stakingly designed to offer superior near-field monitoring per­

formance in professional studio applications. This same superb

performance makes the NS-IOM STUDIO an unbeatable choice for home recording and even audio listening.

‘ In order to make the most of the outstanding sound the NS-IOM STUDIO Monitor Speaker System has to offer, we urge you to read this Owner’s Manual thoroughly.

PRECAUTIONS

FEATURES

Make sure that the power to your amplifier is turned OFF before connecting the speakers.

Do not attempt to drive the speakers at levels above their rated power capacity. Excessive power can lead to serious damage.

Be sure to match the polarity of the speaker terminals

(+, -) with the outputs of your amplifier. If the polarity of the left and right speakers is reversed, proper stereo imaging will be impossible to achieve and irregular re­ sponse will result.

This speaker system is not provided with griiies over the woofers. Avoid touching the woofer cone — particuiariy the center cap — with fingers or any other object to prevent possible damage.

To achieve optimum performance, use audio-quality heavy-gauge speaker cabie.

Woofer

The 18 cm (7") woofer features a conical, straight cone formed from a sheet of speciaiiy deveioped paper materiai, achieving precise pistonic motion for accurate, distortion-free reproduction. The cone weights a mere 3.7 grams, ailowing it to respond ideaiiy even with extremely low Input levels. Power linearity is superb from the iowest to highest input leveis.

Tweeter

The 3.5 cm (1-3/8") tweeter dome is a laminated soft-dome type incorporating two speciaiiy selected resins. A unique manufacturing technique ensures perfectly even resin iayers and forms the dome and tangentiai edge in one piece. The dome and edge unit weights only 0.6 grams, achieving superb transient re­ sponse with minimum distortion.

Enclosure

Only the finest audio-quality high-density particle board is used in this seaied bookshelf-type enclosure. A real-wood exterior with a black finish appiied in 7 coatings adds rugged durability and beauty to profes- sionai-quaiity sound.

Crossover Network

Low-distortion inductors and selected MP capacitors are combined in a carefuliy designed iayout to ensure smooth crossover with minimum loss and distortion.

Speaker Terminals

Large screw-type terminals easily accept heavy-gauge speaker cable for optimum reproduction performance.

CONNECTION

BEFORE MAKING SPEAKER CONNECTIONS, MAKE SURE YOUR POWER AMPLIFIER IS TURNED OFF!

• Connecting the Speakers

The terminals on the rear of the left and right speakers must be connected to the corresponding speaker output terminals on the rear of your power amplifier with appropriate speaker cables. Make sure that the right speaker is connected to the speaker output terminals on the amplifier marked "R" or "RIGHT", and the left speaker is connected to the amplifier output terminals marked "L" or "LEFT." Also make sure that the red ( + ) terminal on each speaker is connected to the ( + ) output terminal of corresponding pair on the amplifier, and the black (-) terminal on *he speaker is connected to the (-) terminal on the amplifier. If the speaker polarities are not properly matched, unstable stereo imaging and distortion will result.

Amplifier

Black Red

First loosen the terminals by screwing counter-clockwise, insert a bared portion of the speaker cable, then tighten the terminal on the cable by screwing clockwise.

• Placement

The NS-10M STUDIO speakers are basically designed for horizontal placement, the speaker marked (A) in the above illustration corresponding to the right speaker and the (B) to the left. According to your requirements, however, the positions of the speakers may be reversed or they may be placed vertically with no effect on reproduction quality. The speakers are marked (A) or (B) to the right of the serial number on the rear panel label.

• Slippage at High Power Levels

Vibration occuring when the speakers are driven at high power levels may cause them to move out of position. This can be prevented by applying the supplied non-slip sheet to the bottom surface of the speaker enclosures.
