Setting up
Insert the threaded end of the telescopic speaker pole into the socket at the
top of the subwoofer unit and turn clockwise until fully tightened in place.
Adjust the pole to the required height, locking in place with the attached
pin. Mount the column speaker onto the 35mmØ pole and face towards the
listeners.
Connect the satellite speaker output (5) to the column speaker using the
supplied SPK lead. Connect a line level (0dB = 0.775Vrms) input to the
balanced XLR input (1) or alternatively to the unbalanced RCA sockets (3) If
further Monolith II sets or other active speakers are to be connected to the
same signal, use an XLR lead from the XLR line output (2) The subwoofer
crossover frequency (7) will determine the point at which the subwoofer
rejects mid and treble frequencies and can be voiced to suit the program
material. Normally, this should be set between 70Hz and 120Hz and is a matter
of personal preference. Connect the Monolith II subwoofer unit to the mains
using the mains IEC lead supplied (12)
Operation
With volume controls (6, 8) turned fully down, switch on the power (4) Turn up the Full Range Volume control (6) part way with audio playing into the subwoofer and check the column speaker for output. Increase the Volume setting to the required level and then gradually increase the Subwoofer Volume level (8) to introduce the correct balance of sub frequencies. Adjust the subwoofer crossover (7) as desired, noting that lower frequency settings may need to be compensated with higher Subwoofer Volume settings. Ensure that volume controls are turned down before powering down and unplug from the mains when not in use for long periods.
