- Data sheet
There are interesting overlaps between the world of music production and reproduction. Studio monitors are such an interesting intersection, and the stereoplay tests showed passed months of time and again, how much sound can provide the Studio world for little money in the living room. Comes with the JBL LSR 4328 a so-called Digital Studio Monitor in the room the first time. This means that the box next to the analogue digital inputs and then numerically processed signal.
The digital monitors such as analog brothers and sisters of the smaller LSR 2328 (issue 10/09) see at first glance, but which betray already the processing and the weight from nearby considered the other class of 4328: rubberized, curved front, more robust housing, side handles and especially the more elaborate electronics. In addition to the balanced analog input XLR – and TRS versions adorn AES/EBU and S/P-DIF-digital input-inputs and outputs (to loop through) at the back. In addition, two RJ-45 Sockets for network cable, a USB and mic jack and a mouse piano can be found. The mini Control Panel is used to address the box in the network.
The here tested complete package LSR 4328 P PAK includes a few 4328 in addition to infrared remote control, sensing microphone and software. These controls and the set using Windows or Apple computer with a long, also attached USB cable.
On the front there is a LED chain with a series of buttons to control and configure the monitor underneath the bass driver. The light and the meter can be Dim and switch off, until on the JBL logo discreetly red glowing even in standby mode. Everything can be controlled via front panel buttons, more convenient, it comes with the remote control, easier to read software.
Analog & digital inputs
First sounds all complicated, but it’s not in practice. The LSR such as each speaker position also. Then he needs power, and you assign the channel via mouse piano, around L = left box. Then comes the network cable to the boxes, with several speakers keep ring-shaped wire. 5 m network cable are included with each box. Now you must decide whether you play analog or digital.
Analog use best the XLR input with switchable sensitivity. Digital, it needs a line to the first box, AES/EBU, or RCA, and then a second, the same cable of the first speaker of the second. Each box picks up one of the two channels from the PCM signal. Turn, if necessary, the input switch on the front, already comes music. Caution: When digital tape the volume must be adjusted now the JBLs either via its front panel buttons or the remote control. Which you should use to aim on the left box, because this serves as master and controls all other via network cable. Also front panel buttons of each box always check all connected monitors.
However, the LSR 4328 can do even more. Once connected, all speakers – can be measured at once up to 7.1 -. To position the inherent measurement microphone at the listening position at head height and wired it to the left box. The measurement program starts by RMC button or software. It gives you a few seconds to exit the room for absolute peace of mind when measuring.
After some sliding sine wave measurements and a commemorative second, the RMC (room mode correction) the dominant space fashion has found mirror image compensates for this, adjusted for any differences in level (balance) and run-time differences to the listening position. RMC automatically sets the filter to the dominant fashion between 20 and 160 Hz with 1/24-th octave precision. A further frequency correction as in Audyssey & co does not take place. You serve manually adjusting high and place low-pass filter with adjustable frequency. These are global in the network, you may not connect so individually want to correct box. JBL stated to this rather impractical solution to solve acoustic problems just acoustically in the Studio, and the high rather served the flavouring or global tonal balance.
EQs in the global network
Once set up, you need the JBLs have one and turn off and, if necessary, according to – and soft marker. The reward: a totally effortless sound. For a Studiomitor, the LSR 4328 sounds even very compliant and emotionally. You seduced stretched, Pleasurable listen and always developed a beautiful musical flow that seduced to the fellow rocker. The tweeter resolves fine and unobtrusive hard structures, without the harsh sounding as the colleagues from the metal camp likes to do this. The plastic cone offers little resistance apparently the power amplifier, so lightly pressing also violent attacks of piano or movie explosions in the area. Also this happens without aggression – unless it already comes from the recording.
In the Studio a good tool represent the JBL LSR 4328 with more relaxed, but certainly more accurate pace, they are even more a gauge as a ruler. At home they invite with their balance and fascinating mixture of fine and coarse Dynamics to long, relaxed listening sessions. Whether digital or analog-controlled, these speakers sound really enjoyable and pleasant correctly.
