Recording and broadcasting studios, sound contractors and musicians will appreciate the low noise, straightforward design, and versatile signal control of the REQ series. INSTALLATION Your REQ series equalizer may be installed in a standard 19î rack or placed in any dry, well ventilated area. The 1/4î connectors are balanced with the tip being positive (+) and the ring negative (-), or will assume an unbalanced state with unbalanced (TS) connectors. The chassis is lifted from the circuit ground (as are all ROLLS products) to help prevent ground loops. Since there are three types of input/output connectors, one type may be used on the input and another on the output. The VOL control provides the boost or cut settings for the input signal level. The LED bargraph shows the actual output level in dB so the use will know when the headroom is exhausted. The HPF and LPF controls are shelving filters , their 3dB down frequencies are indicated on the dials. For widest bandwidth, the HPF should be on 10Hz and the LPF should be set to 30 kHz. Frequency band slider controls cut or boost the indicated frequency by +/- 12 dB for the REQ131, or +/- 6 dB for the REQ215. When the slider is in the center or detented position, the frequency is left unmodified. REAR PANEL The rear panel contains the XLR, 1/4î, and RCA input and output jacks. OPERATION AND APPLICATIONS The REQ equalizers are useful signal processing tools where precise frequency control is needed across the audio spectrum.
