A press patch box is a special audio signal splitter, which is developed for the specific requirements of a press conference. Via separate inputs, you can connect either a microphone or a line signal (mixer output).
Also available as a stereo version (PPB20S)
A high-quality input amplifier with balanced earth-free input allows for a level adjustment over a wide range. 20 transformer-balanced XLR/m jacks with individual driver circuits in pairs are available as outputs for video cameras or other sound recording devices.
The nominal output level is +4 dBu at 600 ohms. In addition, channels 19 and 20 are equipped with TRS phone jacks for balanced or unbalanced signals and with RCA sockets (-10 dBu nominal level).
If more than 20 outputs are required, further PPB20 units can be cascaded via a BUS IN/OUT socket on the rear panel. A 10-fold LED chain and an adjustable headphone amplifier are used for signal monitoring (display range -40 to +10 dB, 0 dB display corresponds to +4 dBu output).
The PPB20 has a built-in shielded power pack. An additional DC input allows for battery operation or using an emergency power supply. PW4 is a suitable emergency power supply for two PPB20.
Passive splitter box for microphone signals. One module has 4 channels. Each channel has an input, an output wired in parallel for passthrough of phantom power, and two splitter transformer-isolated outputs. All outputs are also decoupled via resistors.
The PRMMS8 is an ultra low noise 8-channel microphone splitter providing a direct output and a transformer isolated output for each balanced XLR input. For extra flexibility, four front panel switches enable channel linking which permits routing a single input signal to multiple outputs feeding FOH, monitor, recording and broadcast mixing consoles, or merging two input signals into a single output. For use with condenser microphones, the direct outputs serve as a path for phantom power. Each channel includes a ground lift switch to eliminate hum and interference caused by ground loops between electronic equipment connected to the PRMMS8.
A stereo version of the PPB20 is available in addition to the standard mono version. Instead of a microphone and line input, the stereo version is fitted with two line inputs.
The first line input is distributed to the upper row of outputs (meaning the uneven channels), while the second line input is distributed to the even channels (meaning the lower row of outputs).
The PPB10 is a compact version of the well known and established PPB20 from Palmer. The PPB10 is a 10 channel audio splitter for press conferences and other applications. On a transformer split basis, one line input is split out to ten outputs.
- All inputs and outputs are balanced transformer isolated
- Extremely reliable: Should one output be shorted, the other outputs remain unaffected
- Line input and outputs
- Adjustable input gain (-8 to +25dB)
- Level meter
- Headphone output to monitor the input level, headphone volume adjustable
- Individual ground lift switches for each output
- Ground Lift switch for the input
- Expandable setup thanks to the Bus In/Out sockets - allowing you to cascade numerous PPB10 (or PPB20)
Palmer microphone splitters are used when a signal source has to be sent to multiple inputs. Palmer microphone splitters are used when a signal source has to be sent to multiple inputs. For example, if the microphone signal is to be sent simultaneously to the mixing desk in the hall, the in-house sound system, the monitor mixing desk on stage, and – if the event is broadcast live – to the outside broadcast van. This requires a 1 in 3" microphone splitter. Thanks to the use of generously dimensioned audio frequency transformers, the sound is not influenced, but ground loop hum is prevented. The PMS02 can also be used to convert unbalanced signals into balanced signals and vice versa."
Palmer line splitters are used when a signal source must be sent to multiple inputs. For example, when one mixer output is supposed to supply signals to multiple power amplifiers in different rooms. Thanks to the use of generously dimensioned audio frequency transformers, the sound is not influenced, but ground loop hum is prevented. The PLS02 can also be used to convert unbalanced signals into balanced signals and vice versa.
When I run my guitar into two amps simultaneously, I always get a loud hum". This is a rather common problem, often discussed in the technology section of relevant industry magazines. The Palmer Y box is the solution. Converting the hi-Z guitar signal, the FET input circuitry also drives a transformer which routes the ungrounded signal to the output to eliminate ground loop hum. 9V battery operation is recommended.
The PGA03 Y-box can also be used as a line driver for long cable runs. Also, the PGA03 features a phase reverse switch for the AMP 2 output when using pre-amps or amps that are out of phase."
The Palmer DMS (Dynamic Mic Switcher) routes a microphone signal to two footswitch-selectable outputs.
The Palmer DMS is a passive unit for dynamic microphones only. The switch is instantaneous and is operated via a footswitch.
The DMS provides a wide range of applications :
- Switch your vocal mic between the FOH and monitor mixing desks to communicate with the monitor mixer or the band on stage.
- Two different sound configurations: to switch between different effects or sounds on your microphone, e.g. a telephone effect" or more levels of reverb. Run the outputs of the DMS into two channels of the mixing desk, that you can configure
- You can also use the DMS to route the signal to two rooms or zones and select either one.
