This unit allows you to mix four mono signals with two stereo signals for your own personal monitoring needs. It includes equalization and AGC compression. When coupled with an HM59 or HM58 Headphone Monitor Remote units, the custom mixing can be controlled in separate locations. Please read the following manual carefully to get the best results from your HM60. Sheet 1 of 1 SCHEMATIC 6 BLOCK DIAGRAM DESCRIPTION TOP PANEL MONO INPUTS: Four 1/4" TS unbalanced jacks labeled 1 - 4, for connection to line-level sources such as a mixer's auxiliary sends or monitor sends. EFFECTS SEND: 1/4" TS unbalanced jack for connection to the input of a signal processor such as a reverb or multi-effects processor. STEREO INPUTS: Two 1/4" TRS balanced jacks for connection to a line level source such as a mixer's cue send or headphone output. The Left input is the MONO input and will feed both the right and left channels. EFFECTS RETURN: Two 1/4" TS unbalanced jacks for connection to the output of a signal processor such as a reverb or multi-effects processor. The Right input is the MONO input and will feed both the right and left return channels. The Left input is STEREO and requires a Tip-Ring-Sleeve plug if it is to be used alone. EXPANSION: 25-pin connector - contains all the input signals; the four mono inputs, the main stereo inputs, the effects returns and the power. It connects to the Rolls HM58 or HM59 Headphone Monitor Remote units. [. . . ] Carefully bring up the 1-4 and Main Mix Levels until a desired mix is achieved. AUXILIARY SENDS SUB OUTPUTS MAIN OUTPUTS · 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 frequencies, 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 won't damage your hearing. It also slightly brings up low-level signals. [. . . ]
