PALMER PHDA02 Pro PHDA 02 – Reference Class Headphone Amplifier – 1-channel

The PHDA02 - a reference class headphone amplifier with Stereo, Mono, and Dual Mono operation modes.

In Stereo mode, the L/R input signal is fed to the left and right earphones while the volume level is set by the Stereo/Left control. The front panel inputs provide simultaneous connection of two headphones in parallel. In Mono mode, the left and right channels are summed, and the resulting mono signal is fed to both the left and right earphones. Again, volume is governed by the Stereo/Left control. In Dual Mono mode, the left and right channels can be used independently with individual level controls for the left and right earphones.

The PHDA02 operates with all headphones with an impedance of 8 up to 200 Ohms. Impedance matching is achieved by a specially designed switchable transformer. Uncommon and costly, this solution provides superior performance, dynamic range, and signal-to-noise ratio at all loads.

Combo input sockets allow for balanced XLR and unbalanced TS headphone connection while parallel XLR outputs facilitate daisy chaining multiple units. The integrated power supply operates with mains from 100 VAC to 240 VAC.

The PHDA02 is equipped with low-noise op amps, and the output amplifiers' discrete power transistors are mounted on heatsinks. Dimensions are 1 U 9.5“.

Palmer Monicon, and the volume is right!

With Palmer Monicon, your monitor volume is always under control. The passive mini-mixer with the oversized control is inserted between the stereo output of the notebook, PC or interface and an active monitor system and thus permits convenient and precise volume control of the monitors from the workstation. The passive circuitry with only a few components has absolutely no affect on the sound. Mute and mono buttons make it possible to mute the outputs and merge the stereo output signal into a mono master signal.

The inputs and outputs of the controller are equipped with XLR connectors and the 3.5mm stereo TRS sockets usually found on computers. Combo input sockets also permit connection with 6.3 mm TRS plugs. Thus the Palmer Monicon is compatible with both professional and consumer equipment. Genuine wood sides make the practical studio tool in its massive powder-coated sheet steel housing an elegant looking "little helper" that is a typical Palmer product.

Monitor Mixer Ακουστικών

Πρόβλημα: Ο μουσικός χρειάζεται να ακούει το όργανο του με ακουστικά, μεμονωμένα ή μιξαρισμένο από την έξοδο της κονσόλας, την έξοδο ενός CD player, ή οποιαδήποτε άλλη στέρεο πηγή. Στην κεντρική κονσόλα όμως, πηγαίνει μόνο το σήμα μικροφώνου.

Λύση: Συνδέστε το MyMONITOR ανάμεσα στο μικρόφωνο ,την line πηγή και την κονσόλα .Οι στάθμες εντάσεως καθώς και μίξης του μικροφώνου και line πηγής μπορούν να ρυθμιστούν μέσω ακουστικών. Το MyMONITOR μπορεί να τροφοδοτηθεί μέσω μπαταρίας ή τροφοδοτικού AC και μπορεί να χρησιμοποιηθεί οπουδήποτε, όπως από ένα μεγάλο φεστιβάλ ή σε εφαρμογές όπου δεν υπάρχει η δυνατότητα τροφοδότησης ηλεκτρικού ρεύματος. Δεν υπάρχει περιορισμός στην σύνδεση τύπων μικροφώνων. Εκτός από δυναμικά μπορούν να συνδεθούν και πυκνωτικά μικρόφωνα, καθώς η απαιτούμενη τροφοδοσία 48V μπορεί δοθεί από την κονσόλα μας ή οποιαδήποτε άλλη συσκευή οπού έχει αυτήν την δυνατότητα .

MyMONITOR - Personal Headphone Monitor Mixer Overview

Problem: A performer needs to hear him/herself through headphones exclusively or mixed
with the output of a mixer, CD player, tape deck, or other stereo line level source. Only the
mic signal, however, should be going to the main mixer.
Solution: Connect MyMONITOR between the mic and line source, and the mixer. The Mic
and line Monitor levels can then be adjusted for mix and volume through the headphones.
Only the mic signal will go to the board. And since MyMONITOR can be AC or battery powered,
the unit can be used on a large stage or wherever there is no AC outlet nearby. Dynamic or
condenser mics can be used since phantom power would come through the Mic Thru jack from
the mixer or other source.
