The following information gives detailed instructions on the installation and operation of the SMART MOD V processor. We strongly encourage new owners of the MOD V to thoroughly read this entire manual before placing their new SMART product into service. This will ensure that the MOD V will be operated properly to give the superior performance that it was designed to deliver. [. . . ] If a Pink Noise Card is not available for the MOD V calibration, then an external pink noise source may be used instead. Feed the external pink noise source into the DIGITAL inputs on the rear of the MOD V for the following ISO Cinema playback standard states that 1/3 octave bands should be tuned for flat response to 2 kHz, with a 3 dB/octave rolloff above 2K. 10 5 0 -5 -10 -15 31. 5 63 125 250 500 1K 2K 4K 8K The optional extender card can be used with the Pink Noise Card to calibrate the MOD V. This allows easier access to the Pink Noise Card. Set the pink noise source level for . 55 volts RMS. You must use an analog meter to measure this voltage level. Special Note: The factory settings for digital levels on the External Input/NR Switching Card should be left as they are while using an external pink noise source. This will ensure that the house levels are set correctly. Normally, the digital input levels on the External Input/NR Switching card do not need adjustment, but if they must be adjusted, do so AFTER setting house levels. See the DIGITAL LEVEL SETTINGS at the end of the B CHAIN CALIBRATION section for more information. For the following procedures, select STEREO by pushing the appropriate button on the front panel. Also, set the front panel MASTER FILM FADER to the CAL line, and the trim faders to the 12 o'clock position. EQUALIZATION AND HOUSE LEVELS: The equalizers are normally shipped with the individual trimpots set for a flat frequency response. The 1/3 octave equalizers used for the stage channels are capable of cutting and boosting each frequency band ± 10 dB. The individual trimpots are single turn types, with the mid position of each pot being flat (unity gain). The dual-channel surround equalizer card is a full octave band type. All frequencies on this card are also cut and boost ± 10 dB with single turn trimpots. Remove the MATRIX CARD from its slot and set it aside. Plug the PINK NOISE CARD into the MATRIX CARD slot. Make sure the NORMAL/CHOO-CHOO switch is in the NORMAL position. Turn on the appropriate switch on the PINK NOISE CARD for the channel you wish to equalize. Perform the equalization and then adjust the output trimpot on the OUTPUT/MUSIC CARD so that 85 dBC spl is measured in the auditorium. Do this for the five main channels (Left, Center, Right, Left Surround & Right 16K Surround). [. . . ] This will prevent them from breaking loose from vibration in the future.
