The SR835 is a stereo 2-way, mono 3-way crossover, switchable by means of a front-panel switch with LED indicator. It features 18dB/octave Butterworth filters. The inputs are electronically balanced and unbalanced on 1/4" TRS jacks, while the outputs consist of low and high outputs on both balanced 1/4" TRS and unbalanced 1/4" TS connectors.
In stereo 2-way mode, each channel of the SR835 has a rotary input gain control, in addition to low and high output level controls. The low/high crossover frequency control per channel is variable from 100 Hz to 10 kHz in two ranges. A front panel LED indicator shows when the x10 range is engaged. When switched to mono 3-way mode, channel one's input gain control, low output level control, low/high frequency control, and x10 range switch are active, while the high output level is disabled. The low output level control remains the low output level control in mono mode and the low/high frequency control becomes the low/mid control.
A summmed mono low-output is provided on a balanced/unbalanced 1/4" TRS jack. The unit's power supply is mounted internally, and the transformer and primary side of the power supply are isolated from the secondary side, and the SR835's electronics, by means of a steel hum isolation shield. An optional security cover is available.
