PRESONUS DIGIMAX LT- 8 CH.MIC PREAMP w-ADAT LIGHTPIPE OUTPUT

The DigiMAX LT is essential to the modern digital studio. Eight channels of pristine mic
preamplification, inserts on every channel, and an internal power supply set this unit apart
from anything on the market. Each channel features our award-winning, high performance,
dual servo microphone preamplifiers with 48V phantom power, and -20dB pad. Each channel
features a Neutrik?connector that accepts line level or microphone input. DigiMAX LT digital
synchronization is achieved by offering word clock in and out via BNC connectors. The sample
rate can be set on the front panel to 48K, 44.1K, and 32K providing compatibility across multiple
platforms.
The DigiMAX LT provides TRS inserts on every channel to allow external dynamics processors
or equalizers to be placed in the signal chain. The DigiMAX LT is the perfect partner for recording
systems such as DigiDesign 002?, MOTU828, MOTU 2408? as well as numerous digital mixers
and hard disk recorders.

The PRE-73 Mk2 is the first one-channel low-cost preamp on the market that is using a fully discrete signal path with three separate transformers for the balanced mic input, the line input and the output.

The circuit is very similar to the classical preamp section of the Neve 1073 pre/eq module with a corresponding sound character that is warm, punchy, sweet and musical.
This classical sound has been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres.

The PRE-73 Mk2 has a maximum gain of 80 dB on the mic input and the gain range on the Line input is -20 to + 10 dB. There is also a high-impedance instrument input.

The PRE-73 Mk2 is perfect for almost any signal source, no matter if it's a microphone with a high or low sensitivity (like a passive ribbon mic), a syntheziser or sound module or an electric guitar or bass.

The input impedance of the microphone input can be switched between 300 and 1200 ohms, which makes it possible to affect the tone of most microphones. There is also phase switch and an simple 4-step LED signal level meter.

The output level control makes it possible to make fine gain adjustments and also to overload the main gain stage for more character and then lower the signal to a suitable level before the output stage.

The Mk2 update consists of:
- An unbalanced insert jack (nominal level about 18 dBu) added on the back panel for inserting units like the coming GAP EQ-73, a three band eq.
-  LED meter levels adjusted.
- 600 Ohm termination resistor and jumper added to power supply board (accessible from the inside of the unit).
- Revised Gain switch, turning the know clockwise now increase the gain.
- Reduced noise at high gains by a change to the power supply grounding scheme.

The CPR12 is an easy to use, flexible and multifunctional 10 channel pre-amplifier. Six of these input channels are selectable between Mic / Line level and equipped with a 3 band tone control. The first two can be switched to priority and phantom power. The other four channels are direct line inputs.

Every input channel has its own gain and fader volume control with PFL button which makes it possible to pre-listen each input or output channel with the built-in pre-listening speaker, and can be routed to one or both output channels. This makes the CPR12 a full two-zone system.

Other present features are a priority input, a recording output, separate sub-out channels and the 24 V DC emergency power connection. This last feature makes it possible to power the CPR12 with emergency power when the main power is shut down. In this case, the priority input will automatically mute all input signals, and a evacuation message will be announced. The steel 19" housing has a height of 2 HE.
