Additionally, useful advice about their possible applications is also given. The HA8000 has eight independent amplifiers for connecting headphones, while the HA4700 has four. The latter has several additional features not found in the HA8000 due to space considerations. The differences between the two units are explained in detail in the text sections that follow. Fig. 2. 2: Individual headphones amplifier sections The 8-digit OUTPUT LEVEL display informs you about the ouput signal level of each individual channel, and diplays it in the range between -30 and 0 dB. If a signal is fed into this connector, both MAIN IN signals will be muted. Via these connectors, you can link as many headphone amps as desired to allow for connection of additional headphones. To connect additional units on a per-need basis, you can use HA8000s PHONES OUTPUT connectors. + Please take note: Merely switching the unit off does not mean that it is fully disconnected from the mains. When not using the unit for prolonged periods of time, please unplug the units power cord from the power outlet. The MAIN IN 1 or MAIN IN 2 input signal is selected by using the IN 1/IN 2 switch. When the DIRECT INPUT of the channel has a signal assigned to it, you can hear the said signal only (HA8000 only). When you depress the MONO switch (HA8000 only), the signal is played in mono. Singers in particular appreciate this function because a mono signal is much less distracting to listen to than a comparable stereo signal. A mono signal makes spacial orientation during live performances easier. Fig. 2. 4: MAIN IN and MAIN OUT connectors The MAIN IN connectors of the HA4700 come as balanced 1/4" TRS and XLR connectors. The HA8000 features only 1/4" TRS connectors for MAIN INPUT 1 and MAIN INPUT 2. 2. 2 Rear panel Power is supplied via an IEC connector. Before connecting the unit to a power outlet, please make sure that the selected voltage matches your local voltage. When replacing fuses, please make sure that you always use fuses of the same type. Please note: when connecting a unit intended for the European market to a 120 V power outlet, you must also replace the factory fuse with a higher-value fuse.
