It connects to the Rolls HM58 or HM59 Headphone Monitor Remote units. Consult their respective owners manuals for more information on connecting and operating them properly. 120VAC: Power cord - connect to a properly grounded ac outlet. FRONT PANEL EFFECTS SENDS: These controls adjust the level of signal sent from the corresponding input to the EFFECTS SEND jack. EFFECTS RETURN: Adjusts the level of stereo signal returning from a signal processor (or whatever is connected to the Effects Return jack(s). These inputs may also be used as an additional set of stereo inputs. MIX LEVELS: Controls 1 - 4 and Main; adjust the level of input signal from the corresponding input. MASTER LEVEL: Adjusts the amount of mixed signal sent to the Mix Output jacks. EQUALIZER: These slider controls adjust the level of the indicated frequency. For example, the 64 slider boosts or cuts the 64 Hertz component of the output signal by + or - 12 dB. PWR: Indicates that the HM60 is connected to a power source and is on. BOTTOM PANEL MIX OUTPUT: Phone/Left:For connection to a set of stereo headphones. If a mono Tip- Sleeve plug is connected, this jack becomes the Left Output.

After proper connections are made, begin sending signals to the HM60. Set the Master Level control at approximately 12 Oclock. Carefully bring up the 1-4 and Main Mix Levels until a desired mix is achieved. Adjust the Equalizer as needed. The 64, 125, and 250 Hz sliders control the lower or bass frequencies, the 500, 1K, and 2K sliders adjust the middle frequen- cies, the the 4K, 8K, and 16K sliders vary the high or treble frequencies. 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 notice any effect. Only very high level or low level signals are effected. To use external effects processors, connect the FX Send jack to the Input of your effects unit, connect the output(s) of the processor to the Effects Return jacks (See the connection example on Page 3). If you are using a mono signal out of the processor, use the Right/Mono jack. The Effects Send controls 1 - 4 and Main adjust the amount of signal from the indicated input out the Effects Send jack and to your effects processor. Adjust the Output Level of your processor along with the HM60 Effects Return control to set a desired amount of effect you want. OPERATING THE HM60 WITH THE HM59 OR HM58 HEADPHONE MONITOR REMOTES. Combining the HM60 with the HM59 or HM58 Headphone Monitor Remote units allows users to make and control their own monitor mix. After proper connection of the HM60 to the audio sources, connect the DB25 cable to the HM59 or HM58. From those units, more HM59 and HM58 units may be connected. NOTE: The Effects Sends, Mix Levels, Effects Return, Master Level, AGC Compressor, and Equalizer on the HM60 will have no effect on the signals sent out the DB25 cable to the HM59 or HM58. Refer to the HM58 or HM59 Owners Manual for their proper opera- tion.
