4 CH Line Amplifier - Transformer Balanced Outputs
(Also available: MLA400-2 with Active Balanced Outputs)
Multiple Amplifier Arrays provides you with four identical Line Amplifier channels. These channels may be used as individual independent and isolated amplifiers or they may be combined at internal summing points brought out to the rear connector to form mixers, summing amplifiers, distribution amplifiers etc.
Multiple Line Amplifier Arrays (MLA) apply balanced or unbalanced line level input signals directly to a differential input stage with good common mode rejection and RC bypassing of any RIF signals picked up on the inputs. This stage will accept line levels up to +22dBm (10Vrms) without clipping and has a typical equivalent input noise (EIN) of only -96dBm thus yielding a 118dB dynamic range. More to the point, even with line inputs as low as -20dBm, you will maintain a 76dB S/N ratio. An input impedance greater than 30,000 ohms is high enough to avoid loading of even IHF (phono jack output) lines. A bi-fet input IC (LF347) provides fast and symmetrical slew rate performance along with high loop gain for minimum transient and harmonic distortion generation.

The DMM100 will also match your facility wiring to any RCA, BNC, XLR or TOSLINK(tm) device input. The multiple outputs of the DMM100 are also useful as digital signal splitter/distribution amplifier. The DMM100 utilizes an external power module. A power switch, indicator and Signal Present LED are on the front panel with all signal and power connectors on the rear.
The DMM100-BAT utilizes an external power module or internal batteries (4 AA not included). Battery access is through the top cover.
The MatchMaker Interface Systems match all levels and impedances between unbalanced phono jacks and balanced 600/150 ohm systems.

The DM500’s display tells you everything you need to know about your digital audio signal including input level, sample rate, validity and errors. The stereo VU meter can be switched to indicate either headroom below 0dBFS (the digital maximum output of the D/A) or the analog output level with 0dB midscale equal to +4dBm output. Analog display ballistics are PPM for optimum indication of audio peaks.
The DM500 is ideal for digital signal troubleshooting on the go, but is equally at home on the bench or in your rack. Audio loop-thru connectors let you insert the DM500 into your digital signal path, with input termination also provided. An external 120V power supply is included.

DDA-106 Series 2 Digital Audio Distribution Amplifiers are designed to regenerate, isolate
and distribute digital audio data formatted in accordance with specifications AES3-1992 and
IEC 958. This is commonly called AES/EBU formatting or AES3.
DDA-106 Series 2 units have two inputs, selectable from a front panel switch. The selected
input feeds AES audio to six separate outputs. A front panel switch selects either reclocking
or non-reclocking of the input signal. In most cases, re-clocking is preferred, as this
feature improves the integrity of weak or distorted input signals. Re-clocking may be
switched off to allow distribution of AES sync signals, Dolby E encoded AES signals, or
other signals that should not be re-clocked.

Studio Master Clock Generator & 12X Clock Distribution Amplifier
When you work with digital audio, you need a stable sync reference for all of your audio components. The MCDA112 provides both an ultra-stable clock reference and a 1X12 clock distribution amplifier in a single 1RU enclosure.As a master clock generator, the MCDA112 provides a total of 12 Word Clock or Super-Word Clock output signals to sync up to 12 devices in your studio. You can select between 44.1, 48, 88.2, 96, 176.4 and 192 kHz sample rates with a dedicated front panel button. The MCDA112 can also function as a 1x12 Clock Distribution Amplifier, accepting AES, Word Clock or Super-Word Clock as an external input and providing either Word Clock or Super-Word Clock to all 12 of its outputs.
The MCDA112 bears the ATI Digital Audio logo assuring top performance and innovative circuitry. The internal clock reference is derived from a 24 MHz precision oscillator and divided down to achieve an ultra-stable signal, rather than multiplying up from a base reference as in some other units. All functions are fully addressable from the front panel, and a unique front panel control lock can protect your settingsLink : http://www.atiaudio.com/ViewManual.aspx?CurPage=MCDA112
