Modulation Sciences MSI-3300 Television Audio Processor AES-3id / Analog

Audio Processing for TV in the Digital Age

Overview

Setup is a snap and the 3300 offers superb, wide, dynamic gain riding and limiting at affordable prices.

The MSI-3300 Conditions audio for transmission in any medium:

Cable modulators
Satellite uplinks
Fiber modulators
STL’s and other microwave channels
Aural transmitters
Cable stereo generators
Perceptional coders, such as MPEG and Dolby AC3 and E.
Telco lines

Features

Behaves like a human operator

The built-in automatic gain riding feature enhances as well as reduces gain in your audio, depending upon the program content. During consistent programming, 3300 levels out the varying audio levels, during silence the 3300 freezes the gain, it can also sense dramatic fades and allows them and doesn't track slow fades into the noise floor. It's like having an additional audio operator.

TV Program Material Varies

The varieties of audio are endless. In order to process them all, an operator has to continually switch the audio or you can use an MSI-3300 and it will do the job for you.

Specifications

AC MAINS

Input Power:	22VA, 115 VAC

Operating Range:	108-122/216-244 VAC, 50/60 Hz

INPUTS

Analog:

Nominal input level (APL): -24 dBu, minimum

Impedance: 600 Ohms as shipped, balanced 30K (internal option), balanced

Connectors: XL-3 Female

Digital:

Format: AES3-id, transformer coupled

Sample rate: 32-48 KSPS (auto sample rate converter)

Word length: 24 bit max (internal I2S)

Connector: BNC

Selection:
Valid digital input is taken. Invalid or no digital input takes analog input. An internal jumper can force analog selection.

OUTPUTS

Analog

Nominal output level (peak, with control): +10 dBu, +10 dBm/600 Ohms

Maximum output level (peak): +18 dBu, +18 dBm/600 Ohms

Adjustment range: 20 dB

Source impedance: <50 Ohms, balanced & floating

Connectors: XL-3 Male

Digital:

Format: AES3-id, transformer coupled

Sample rate: 48 KSPS

Word length: 24 bit

Connector: BNC

GAIN CONTROL

Overall static gain (ctl off):

Analog: Adjustable

Digital: 10.6 dB

Processing gain with respect to static gain: +10 dB max -10 dB min indicated approx -20dB possible

Assumed digital APL: -16.4 dBFS on input

Range of threshhold adjustment: 3dB

ADAPTIVE PRE-EMPHASIS CONTROL
(This is an internally jumper selected control option.)

METER INDICATIONS
Time constant:	75 microseconds

Inflection frequency of control:	Variable

Range of threshold adjustment:	0-6dB above wideband

FIXED OUTPUT DE-EMPHASIS (This is an internally jumper selected option.)

Time constant:	75 microseconds


Input:	L only with 10dB peak marker R only with 10dB peak marker L&R together

Output:	L only with +10dBu marker R only with +10dBu marker L&R together

Level matching:	Log peak of Input (L-R) Log peak of Output (L-R)

Wideband AGC:	Operating gain over range of +10 to —10 dB

Adaptive pre-emphasis (HFL):	High frequency gain (15kHz) From 0dB to approx —17 dB

Messages:	HFL not enabled Digital input selected Pre-emphasis enabled

Alarm:	Input polarity reversed

MECHANICAL

Mounting	EIA 19" rack, 1U high

Depth	16"(406mm) plus connectors

Weight	Approx 6 kg (13 lbs)

ELECTRICAL PERFORMANCE
Frequency Response

Digital input to Analog or digital output:	+/-0.5dB, 30Hz-14kHz

Analog input to Analog or Digital output:	+/-0.5dB, 50Hz-14kHz

Analog input high-pass filter:	-3dB at 30 z/18dB/oct (The HPF can be bypassed)

Notes: The unit incorporates a 15.7kHz notch filter and BTSC system alias protection LPF. These filters are always present in both the analog and digital input paths

The same tolerance is met when the HFL is engaged along with the fixed output de-emphasis option, with control off. With control on, the input level must be reduced below the HFL theshhold, in which case the tolerance is also met.

With HFL engaged and no output de-emphasis, the 75usec pre-emphasis is accurate to a smaller tolerance (typically +/-0.2 dB), with control off or at level below HFL threshold.

(THD+noise): Either input to Digital output at -1dBFS <0.1%, 30Hz-14kHz
Either input to Analog output at +10dBu <0.1%, 30Hz-14kHz

Crosstalk: Analog inputs to either outputs >50dB, <10kHz
Digital inputs to either outputs >55dB, <10kHz

Output noise: Either inputs to Digital out -83dBFS
Either inputs to Analog out -72dBu
