[. . . ] 300 Digital Effects System V 3. 0 Owner's Manual Unpacking and Inspection After unpacking the 300, save all packing materials in case you ever need to ship the unit. Thoroughly inspect the 300 and packing materials for signs of damage. Report any shipment damage to the carrier at once; report equipment malfunction to your dealer. Precautions The Lexicon 300 is a rugged device with extensive electronic protection. However, you should observe the same reasonable precautions that apply to any piece of audio equipment. [. . . ] DLY3 feeds from the left delay position to the input of the right delay line. The same is true with DLY4 feeding into the left delay line. The feedback parameters adjust the amount (level) passed into the destination delay lines. The last pair of delay pointers (LDLY and RDLY) can be thought of as independently adjustable post delays. These can be adjusted anywhere along the 2. 5 second delay line. The output of each delay line can be positioned anywhere in the stereo pan field. LPAN adjusts the position of the left delay loop; RPAN positions the output of the right delay loop.

FDLY (Flange Delay) LFBD and RFBD are base delays which get summed with the stereo ganged flange delay. These base delays are adjustable in single sample steps throughout a 20 millisecond range. LFBD and RFBD (Left and Right Flange Base Delays) LFLG and RFLG are flange gains which are adjustabe as a feed forward amplifier loop (+99% positive value) or feedback amplifier loop (-99% negative value). LFLG and RFLG (Left and Right Flange Gain) Dual Delays Diffusors, Feedback and Delays DLY1 and DLY2 set the delay values for the respective left to left and right to right feedback loops DLY1 and DLY2 FBK1 and FBK2 set the gain of feedback for each of the delay lines. Available values range from -99% to +99% gain. FBK1 and FBK2 APD1 and APD2 are diffusors (All Pass Delays) in series with the feedback loops associated with DLY1 and DLY2. These controls essentially "tune" the diffuor delay line. APD1 and APD 2 (All Pass Left and Right Delays) APG1 and APG2 are gains associated with the diffusors. You can think of them as controlling the amount of diffusion. APG1 and APG 2 (All Pass Left and Right Gain) DLY3 and DLY 4 DLY3 controls the delay time which cross-feedbacks to the input of DLY2. DLY4 controls the delay time which cross-feedbacks to the input of DLY1. FBK3 and FBK4 control the gain of the feedbacks going with each of their respective delay lines. FBK3 and FBK4 LDLY sets the left channel delay line's time. RDLY sets the right channel delay line's time. LDLY and RDLY LPAN adjusts the left delay channel pan placement. RPAN adjusts the right delay channel pan placement LPAN and RPAN 4-25 300 V 3. 0 Owner's Manual Lexicon Split Chamber General Description The Split Chamber program provides several presets which can be loaded into any Dual Mono or Cascade setup. In the Dual Mono setups it passes audio Mono In-Mono Out. In the Cascade setups, audio is routed Mono In-Stereo Out. The Split Chamber program can simulate many different types of acoustic spaces or mechanical devices. Th Split Chamber algorithm is great on anything. SIZEs of 25 and larger set a lower acoustic density. SHAP and SPRD help create the illusion of larger spaces whicle using short reverb times. As in the Random Hall algorithm, the LINK parameter couples SIZE to the RTIM and SPRD. Unlink provides a method of setting stable RTIM and SPRD values, then adjusting SIZE to set the right density and "tuning". [. . . ] Check the Automation mode on the MIDI Control page in Control mode. This should be set to SYS EX or NON-REGISTERED PARAMS. 8-2 Troubleshooting The 300 does not change effects to incoming time code. Check your cable connections and the setting of the Event List mode in Control mode. Also check the signal level of the incoming time code. [. . . ]
