High Frequency Adjustment; Changing Mid/High Orientation - JBL LSR Owner's Manual

Use only two conductor insulated and stranded speaker wire, preferably no smaller than 14 AWG.
Cable runs exceeding 10 meters (30 feet) should be made with heavier wire, 12 or 10 AWG.

3.2 High Frequency Adjustment:

The LSR32 High Frequency level can be adjusted to compensate for placement or "bright" rooms.
The unit is shipped in the "flat" or 0 dB position. If the unit sounds too bright in your room, or you are work-
ing very close to the monitors (under 1-1.5 meters) the response above 3 kHz can be brought down by
approximately 1 dB.
This adjustment is accomplished via the barrier strip on the back of the enclosure located above the
dual pair of 5-way binding posts. Moving the link between the 0 and -1 dB position will change the high fre-
quency drive level. Please note that the loudspeaker should be disconnected from the amplifier during this
procedure for safety of the system and yourself.
3.3 Rotation of Mid/High Transducers:
The LSR32 is normally used in the horizontal position with the mid- and high-frequency elements
toward the middle. This provides the lowest elevation, maximizes sight lines and reduces shadowing effects of
soffit mount monitors. In situations where vertical orientation is desired, the entire Mid/High sub-baffle can
be rotated.
NOTE: The mid and high transducers can be easily damaged by wayward screwdrivers. Take great
care to protect them as long pointy objects tend to have negative effects on performance which are
not covered under warranty.
1. Place the LSR32 on its back on a stable surface.
2. Carefully remove the eight phillips screws surrounding the Mid/High sub-baffle.
3. Gently lift the baffle out enough to rotate the assembly. You can use your hand in the port to assist. Do not
pull the unit out entirely. This avoids unnecessary tension on the cabling assemblies.
4. Replace the eight screws and tighten. Again, take note to be VERY careful to guard against transducer
damage.
