21、 All HM58 controls adjust the levels of input signals connected to either the HM60 or HM57. With the exception of the HM60 Effects Send controls, all other HM60 knobs will have no effect on the signals sent to the HM58. MAIN IN:Controls the level of the main Stereo Input FX RETURN: Adjusts the level

22、 of signal returning from a signal processor which is connected to an HM60. BASS: Boosts or cuts the low frequency portion of the signals sent to the Head- phone Output. When in the 12 Oclock position, the knob has no effect. MID: Boosts or cuts the middle frequency portion of the signals sent to th

23、e Headphone Output. When in the 12 Oclock position, the knob has no effect. TREBLE: Boosts or cuts the high frequency portion of the signals sent to the Headphone Output. When in the 12 Oclock position, the knob has no effect. AGC COMP: This switch engages the Automatic Gain Control compressor. MAST

24、ER OUT: Controls the level of all signals sent to the Headphone Output. OUTPUT: 1/4” TRS stereo jack containing all mixed and processed signals. PWR: LED indicating that the HM58 is properly connected to the HM60 or HM57 and is receiving power. AUX1 - AUX4: Adjusts the level of input signals to from

Set the HM58 Master Level control at approximately 12 Oclock. Carefully bring up the AUX 1 - 4

27、levels until a desired mix is achieved. Adjust the Equalizer as needed. The AGC compressor keeps transient signals like pops or feedback under control, so they wont damage your hearing. It also slightly brings up low-level signals. NOTE: Much of the signal content may not be compressed, you may not

28、notice any effect. Only very high level or low level signals are effected. If using external effects processors, make sure they are properly connected to the HM60, and the levels are set properly. Refer to the HM60 owners manual, as well as the operating manual of the effects processor. If you have

29、an effects processor connected to the HM60 control unit, the HM58 Effects Return adjusts the level of the effected signals to your headphone mix. Note that the Effects Sends 1 - 4 and MAIN on the HM60 determine the mix of signals sent to the effects processor. The HM58 FX Return control will only ad

30、just the level of that mix. In other words, the signals present at the Right and Left Effects Return jacks on the HM60 will be the signals adjusted by the FX Return control on the HM58. CONNECTION CONNECTING THE HM58 Shown below is a connection diagram for the HM58. The male Expansion jack, shown be

31、low on the left side, is the INPUT, the female Expansion jack, shown here to the right, is the OUTPUT or through jack. So connect the DB25 expansion cable from the female OUTPUT Expansion jack of either the HM60 or HM57 to the male INPUT Expansion jack on the HM58. The female OUTPUT Expansion jack o
