PALMER PRMMS Pro PRMMS – Microphone Splitbox 4 Channel

• Each channel: Input: female XLR type
• Outputs: 1 parallel male XLR type, 2 transformer isolated male XLR type
• Nominal impedance for inputs/outputs: 200
• Max. input level: + 6 dBu

The distribution of mono and stereo balanced audio signals from a single source to multiple destinations has many applications including multi-zone sound reinforcement installations, live sports events coverage, broadcast studios, video suites, duplication or indeed anywhere high quality audio has to be distributed to a number of locations down long cable runs.

The Drawmer DA-6 is a six channel stereo (or twelve channel mono) distribution amplifier featuring XLR balanced inputs and outputs with optional transformer balancing where remote amplifiers and recorders are fed from separate power supplies.

The stereo Input features individual left/right level controls with LED bargraph metering enabling the correct balancing of stereo material or two mono signals. Each of the six outputs incorporate further left/right level controls and a Mono/Stereo switch providing the selection of either one stereo output or two mono outputs per channel. This feature allows the DA-6 to function as either a 1 x stereo input/6 x stereo outputs or 1 x mono input/12 x mono output unit or any combination of the two.

The output section consists of a Channel Select so that the individual left/right output level of each channel is displayed on the output LED bargraph and can be monitored by the Headphone jack socket. A pair of auxiliary link stereo jack sockets (TRS) are provided via the rear panel for connection to further DA-6 units for the distribution of even more channels.

• 1x6 Stereo Distribution Amp with Monitoring.

• 6 sets of stereo (2) XLR outputs.
• Input stage has LED level meter.
• Each output channel can be switched to mono.
• Each output channel can be individually monitored.
• Built-in headphone amp.
• Optional transformer balanced outputs.
• Electronically balanced inputs with individual left/right level controls.
• LED metering on input for balancing stereo material or two mono signals.
• Left / Right level controls on each output with a stereo / mono switch.
• Headphone jack to monitor output of selected channel.
• LED metering on output of selected channel.
• Auxiliary pair of balanced 1/4" output jacks for linking multiple DA6 units.
• 1 unit rack space.
• Inputs and Outputs are balanced XLRs at +4dBu.

A passive dual channel line splitter that is mainly used to feed the left and right master outputs of a mixer into several inputs such as power amplifiers, recording machines etc. A specially designed audio frequency transformer maintains signal integrity and prevents ground loop hum. This unit also converts unbalanced signals into balanced signals and vice versa. Rugged diecast aluminium box.

Flawless performance in any audio environment

Today?s venues face a growing need to provide a multiplicity of audio feeds
from presentations, conferences, orchestral performances and lectures. The
advent of digital broadcasting, the growth of webcasts and direct-to-CD
archiving highlight the deficiencies in audio splitting systems more than ever
before. Whether the final product is a broadcast feed or CD sales of an unrepeatable
lecture, performance or event, end-users? expectations of audio quality are
higher than ever.With these requirements in mind, ARX has developed the
MSX 8 Active Microphone/Line Splitter to deliver the performance required by
today?s standards of audio production. Active microphone and line splitting has
a number of benefits over passive splitters: primarily these are improved sound
quality, noise figures comparable to the best microphone inputs, and increased
resistance to RFI. All of which translate into superb audio quality for your clients.
About the MSX 8
The MSX 8 consists of two channels of actively buffered ultra low noise Microphone/
Line Splitter. Each of these channels has four electronically Balanced splits ? two
on the rear panel, plus two more on the front panel. All four output splits have the
option of transformer balancing if so specified.Each channel has a ?20 dB pad switch
plus silently switchable 48V Phantom power with indicator LED.Gain through the MSX 8
can be set individually by the small DIP switches on the rear of each channel, from 0dB
through to +40 dB in 10 dB stepsA ?Link? switch links Channel 1 to Channel 2, providing
an ultimate maximum of 8 Outputs from a single input. An indicator LED shows when this
is active. A Clip LED indicates imminent signal overload through the channel, and a
numbered marker panel on the front provides a space where individual channel connections
can be noted.For remote or mobile applications a 5 pin DIN connector on the rear panel
provides an access point to connect a 12V DC power supply
Inside Information
Internally, powerful RF input filtering removes both common mode and differential interference
at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components
throughout.Advanced user options include internally jumper linking Inputs to Main outputs, and
Ground lifting Output Pins 1as required.
Internal Power Supply
The MSX 8 has a low noise transformer based power supply to obtain the maximum benefit from
the ultra low noise design of the splitter circuitry.
Summing up, the feature packed MSX 8 is the answer wherever transparent signal buffering and
routing is required.
