PMJT2000Wireless Headphone System

R User and Installation Guide 2.4 GHz DIGITAL Wireless Headphones Model 2000 User and Installation Guide Page 1 R Step 1 Connecting the transmitter The transmitter provides 2 digital interfaces and 1 analog interface to connect to an audio source. The transmitter accepts a digital audio signal at both the electrical and optical digital interface. By using one of the digital interfaces, audio data can be fed directly into the transmitter. This bypasses the digital-to-analog and analog-to- digital conversion and thereby eliminates audio distortion. Many HiFi components provide a digital audio interface. The format of the digital audio which is fed into the transmitter must be uncompressed S/PDIF stereo data at a sampling rate of 32 kHz, 44.1 kHz or 48 kHz. Compressed multichannel audio data (which is provided by many DVD players) cannot be processed by the transmitter. In such case, set the format of the DVD player audio interface to uncompressed stereo data. Connect the digital audio output of the audio source with the digital audio interface of the transmitter by using an RCA cable if the electrical interface is used. If the optical interface is used, connect the transmitter by using an optical audio cable (not included). Connect the DC power input with the supplied AC adapter. The use of a surge protector is recommended to protect the transmitter from power surges and audio dropouts. Digital Audio Interface Analog Audio Interface DC Power Input Analog audio can be fed into the transmitter via the analog audio interface. Analog audio is converted to digital audio inside the transmitter by an analog- to-digital converter. The analog audio interface can be connected to a line out interface which is provided by most audio sources. The analog audio interface can also be connected to other analog outputs by using an appropriate adapter. The transmitter will accept maximum audio levels between 0.2 Vrms and 10 Vrms. Prior to operating the transmitter, the analog audio interface should be set to the correct audio level by adjusting the analog audio interface level control (see page 7).

Therefore, it should be carefully considered where to place the transmitter. Below, two examples are given. In the first example, there are 4 walls between the transmitter and the receiver. The transmission may be interrupted. By locating the transmitter such as in the second example, reliable transmission to all of the 6 rooms is possible. Also, the elevation of the transmitter as well as the presence of reflecting walls will influence the range. It is suggested to experiment in order to find the best location for the transmitter. If sufficient coverage cannot be achieved by changing the location of the transmitter, then the use of RangeBooster transmitters is suggested. These RangeBooster transmitters are available as an accessory for your 2.4 GHz Digital Wireless Headphones from Amphony and can be located in areas where signal reception is difficult. RangeBooster transmitters connect to the DATA OUT output of the transmitter and receive the signal in a digital format without any degradation. Any number of RangeBooster transmitters can be used to extend the operating range almost indefinitely. Example 1:Poorly chosen transmitter location Example 2:Improved transmitter location User and Installation Guide R User and Installation Guide Page 4 R Step 3 Charging the batteries Prior to operating the headphones, the batteries have to be charged. Four rechargeable NiMh batteries are supplied. Insert two of the batteries into the battery charging bays of the transmitter. The two lights “Battery 1” and “Battery 2” of the transmitter will light to indicate that the batteries are being charged. In order to operate the headphones quickly, leave the batteries inside the charging bays for a few hours. In order to fully charge the batteries, leave them inside the charging bays for 48 hours. After removing the batteries from the transmitter for use with the headphones, insert the second pair of the batteries into the charging bays. The second pair will be charged while the first pair is being used inside the headphones. After the headphones stop working because of low batteries, switch the first pair of batteries with the pair inside the transmitter charging bays. The batteries can remain inside the charging bays for more than 48 hours. The transmitter will keep the batteries fully charged while inside the charging bays. R Battery charging bays Battery charge lights User and Installation Guide Page 5 R Step 4 Inserting the batteries into the headphones After charging the batteries, insert them into the headphones. There are two battery compartments, located on both sides, each housing one battery. To access each battery compartment, push on the outer edge of the battery lid. This will release the battery lid. Then lift the middle portion of the battery lid to gain access to the battery compartment. Insert the battery by pressing the minus pole of the battery against the spring at the bottom of the battery compartment until the plus pole can slide into the battery compartment. The battery should snap into place. Ensure that the plus pole of the battery properly contacts the battery c…

Measuring Methods 5.1. Conducted powerline emissions Rules and Specifications: Sections 15.107 & 15.207 Guide : CISPR 22 Measurement Procedure: In general conducted emission tests in the frequency range 0.15 ñ 30 MHz are required to be performed with quasi-peak and average detector. To simplify testing the following procedure is used: First the whole spectrum of emission caused by equipment under test (EUT) is recorded with detector set to peak. After that all emission levels having less margin than 20 dB to or exceeding the appropriate limit (in general average limit is 10 dB lower than quasi-peak limit) are retested with detector set to quasi-peak. If average limit is kept no additional scan with average detector is necessary. In cases of emission levels between quasi-peak and average limit an additional scan with detector set to average has to be recorded.

Field Strength of Emissions Measurements in fully-anechoic Room Rules and Specifications: Sections 15.109, 15.209, 15.249 Guide : ANSI C63.4 1997 Measurement Procedure: Radiated emissions are measured over the frequency range from 30 MHz to the 10 th harmonic of the maximum frequency of the EUT for transmitters and to the 5 th harmonic for receivers. Measurements were made in both the horizontal and vertical planes of polarization in a fully anechoic room using a spectrum analyzer with the detector function set to peak and resolution bandwidth set to 100 kHz for emissions below 1 GHz and to 1MHz for emissions above 1 GHz. All tests were performed at a test-distance of 3 m…
