TBV BERLIN SERIES
LAKE Preset Overlays and Application Notes
TBV Series preset modules for LAKE LM series controllers and LAB GRUPPEN / LAKE DSP amplifi ers (PLM+, D Series L) include preset overlays to assist with system
tuning and optimisation. Four preset overlays are available: 2 BOX ; 3 BOX ; Long Throw (LT) and Band Level EQ (BLEQ).
Notes:
1. When 2 BOX and 3 BOX overlays are both bypassed, processing is suitable for use with a single TBV123 enclosure (1 BOX mode).
2. When the Long Throw (LT) overlay is bypassed, nominal fl at performance is obtained (referred to as Short Throw ST mode).
3. When operated in passive (1W) mode, TBV123 HF OUTPUT LEVEL switches should be set for MID THROW operation. When operated in bi-amplifi ed (2W) mode,
TBV123 HF OUTPUT LEVEL switches are bypassed and do not have any eff ect on HF output level.

OVERLAY DESCRIPTION
SHORT THROW Mode provides nominally-fl at low and high frequency response
under freefi eld conditions and is suitable for systems consisting of 1-3 TBV123
enclosures operated in either 2-Way (bi-amplifi ed) or 1-Way (passive) mode.
Short throw applications include: distributed front fi ll, stereo infi ll, under-balcony
fi ll and stacked, tripod-mounted or pole-mounted systems intended for short
throw front-of-house or sidefi ll stage monitoring.
SHORT THROW performance is obtained when the Long Throw overlay is bypassed
and can be selected for 1 BOX, 2 BOX or 3 BOX operating modes.
LONG THROW Overlay is intended for medium- to long-throw applications and is
suitable for arrays consisting of 1-3 TBV123 enclosures when they are suspended
using the TBV123-FB Fly Bar. High-frequency shelving pre-emphasis compensates
for air absorption over typical throw distances and is combined with low
frequency shelving to provide an enhanced LF contour.
LONG THROW performance is obtained when the Long Throw overlay is active and
can be selected for 1 BOX, 2 BOX or 3 BOX operating modes.
1 BOX MODE is intended for use with a single TBV123 enclosure and can be
used with the Long Throw overlay active (LONG THROW mode) or bypassed
(SHORT THROW mode) depending on the application.
1 BOX MODE is obtained when 2 BOX and 3 BOX overlays are both bypassed.
