[. . . ] If a problem occurs during the warranty period, the unit will be repaired, or replaced at our option, without charge for materials or labor. If air freight is requested by the dealer, the difference between air and surface charges will be billed to the dealer. This limited warranty does not cover products that have been abused, altered, modified, or operated in other than specified conditions. [. . . ] The crossover slopes are 24 dB per octave (utilizing 4 pole active filters) to provide a smooth blend of sounds from the low, mid and high frequency components. The steep 24 dB slope also provides maximum protection for the high frequency driver during loud sound passages. When a 2-way speaker reproduces a note at (or near) the crossover frequency, both the HF and LF speakers are working at that frequency. Because the HF driver cannot be physically aligned with the LF woofer, the HF sound arrives at the listener's ears slightly behind the sound created by the LF woofer. This creates a muddy, confused sound in the overlap frequencies where misaligned pressure fronts of the corresponding frequencies cancel each other out. For example, if a 2. 5 kHz tone is electrically delayed in the high frequency band so that the corresponding tone New CD horns can hold their pattern throughout the high Figure 2. Acoustically unaligned 3 way speaker audio frequency range. Because the pattern is so wide, the system. higher frequencies are spread over a bigger and appear not to be as loud as their lower counterparts. The TCX924 has CD horn compensation built in. The smooth high frequency boost is up 12 dB at 10kHz from the Crossover frequency of 2. 5 kHz. This high frequency boost is valuable for movie theatres because of screen attenuation losses at high frequencies. Equalization is easier and smoother with the CD horn correction added. SECTION 2 6" INSTALLATION Mount the TCX924 in the equipment rack where it is in proximity to the power amplifiers. An ideal location is where the TCX924 output leads can easily reach the Figure 1. The TCX924 Front panel with Security Cover removed. 2 INSTALLATION AND OPERATION inputs of the power amplifiers with a minimum run of cable. Wire the outputs to the respective inputs of each power amplifier making sure the LF outputs arrive at the LF amplifier inputs. Mixing the LF, MF, and HF signals can cause damage to the drivers. [. . . ] The OFF position is also the bypass mode that allows the audio signals from each channel to pass to the amplifiers. A special protection circuit is included in the bypass circuits to protect the MF and HF drivers from damage from low frequency energy. The LF woofers will receive full range audio when the TCX924 is in the bypass mode. [. . . ]
