3 Installation in Brief 3 I NST ALLA TION IN B RIEF W e know that you are eager to hear your new Depth sub- woofer , so this section is provided to allow fast and easy set up. Once you have it operational, please take the time to read, in depth, the rest of the information in this manual.
4 Introduction and Assembly I NTRODUCTION AND A S SEMBL Y Congratulations! Y ou have invested in one of the world's premier subwoofers. The MartinLogan Depth represents the culmination of an inte.
Level Knob Setting the level too high will cause the bass to seem bloated and is the single most common cause of bad sounding subwoofers. A rule of thumb is that the subwoofer should not draw attention to itself , but should simply make the systems low end seem more extended and accurate.
C ONNECTIONS AND C ONTROL S ET TINGS MartinLogan engineers designed the Depth for easy setup and system integration. Before beginning to connect your Depth, please review the controls discussed in the last sec- tion. An understanding of these will help speed you along as you connect your Depth with your system.
Connections and Control Settings 7 Multi-Channel Mode This setup is recommended if your Depth will be used in a dedicated home theater or multi-channel system. When a signal is connected to the Depth ’s LFE input, Depth ’s internal low pass filter is not active.
8 Connections and Control Settings Using an A/V processor and the Depth ’s low pass filters. This setup is recommended if your Depth will be used in both 2-channel mode and as a LFE (0.
Connections and Control Settings 9 This setup is recommended if your Depth will be used in a 2-channel only system. When a signal is connected to the Depth ’s Left/Right Inputs, the Depth ’s internal low pass filter is active.
10 Connections and Control Settings This setup is recommended if your Depth will be used in a 2-channel only system and you intend to use the Depth ’s High P ass F ilter Out. Signal Connection (see figure 10): 1 Connect the left and right outputs of your preamplifier to the left and right inputs of the Depth using quality RCA interconnects.
Using Sub Out offers an easy way to implement multiple Depth ’s in your audio/video system. Note: All additional Depth subwoofers must run as either dedicated 2-channel (stereo) or multi-channel (LFE) sub- woofers, but not both. Signal Connection: 1 Connect the first Depth to your system using one of the five modes previously described.
12 Connections and Control Settings WARNING! The power cord should not be installed, removed, or left detached from the subwoofer while the other end is connected to an AC power source. The IEC power cord should be firmly inserted into the AC power receptacle on the rear connection panel of the Depth, then to any convenient AC wall outlet.
P LACEMENT Placement 13 Generally , subwoofers have the most output when placed in the corner of a room. However , this can also exaggerate the subwoofers output making blending difficult. W e recom- mend starting by placing the Depth in a corner . It should be placed in such a way that there are 2 inches between the grill cloth and the wall.
T erminology 14 Room Acoustics This is an area that requires both a little background to understand and some time and experimentation to attain the best performance from your system. Y our room is actually a component and an important part of your system.
After living and experimenting with your Depth, you may want to use the ETC ™ (Energy T ransfer Coupler) Spikes (see figure 17), included with your Depth. With the use of these spikes, the Depth subwoofer will become more firmly planted on the floor and, consequently , bass will tighten.
It had long been the practice of stereo buffs to connect their television to the stereo system. The advantage was the use of the larger speakers and more powerful amplifier of the stereo system. Even though the sound was greatly improved, it was still mono and limited by the broadcast signal.
Resulting from an equal and opposite reaction to the cone's movement, strong bass causes traditional subwoofer enclo- sures to generate acoustic vibrations.
