2 Use the cursor buttons to select the parameters, and use the Parameter wheel, INC/DEC buttons, and [ENTER] button to set them. SPEAKER SETUP: These parameters are for setting the volume balance of the surround monitor speakers. Select the OSC (Oscillator) parameter and choose from PINK NOISE, 500-2K (pink noise through a 500 Hz to 2 kHz BPF), 1K (1 kHz sinewave), or 50 Hz (50 Hz sinewave). Use the ON/OFF button to turn the Oscillator on and off. When on, the Oscillator outputs a signal at –20 dB to the Surround Channels whose icons are highlighted. You can turn on and off Oscillator output for speakers individually. Speaker icons can be selected by using the cursor buttons. The signal phase of the LFE Channel can be reversed by using the SW phase button. When ROTATE is on, the Oscillator signal is output by each speaker in turn in a clockwise direction (3 second signal, 2 second pause).

Note: If you had been monitoring with the surround mode set to 6.1 and the monitor matrix mode set to 6.1 on DM2000 units with system software earlier than V2.1, the playback may not always be correct on V2.1. MONITOR MATRIX: This is used to select the Surround Monitor Matrix. In 6.1 Surround mode, you can select 6.1, 5.1, 3-1, or ST. In 5.1 Surround mode, you can select 5.1, 3-1, or ST. In 3-1 Surround mode, you can select 3-1 or ST. When a down mix Monitor Matrix is selected, you can attenuate signals by using the ATT parameters. You can use the Surround Monitor settings in Stereo mode, but Monitor Matrix is fixed to ST. Note: If you choose monitor matrix mode = 3-1, you must set the following three attenuation amounts to the same value. • ATT1 for surround mode 3-1 • ATT4 for surround mode 5.1 • ATT5 for surround mode 6.1 These ATT values are not attenuators for down-mixing; rather, they are used as monitor adjustment attenuators for lowering the playback volume of the Ls, Rs, Ls2, and Rs2 speakers. The following screen shows an example in 6.1 Surround mode and 3-1 Monitor Matrix mode. • BASS MANAGEMENT You can set the filter and attenuator settings for each Surround Monitor Channel using eight preset Bass Management modes. The following presets are available: Presets Parameters No. Title HPF 1, 2, 3 LPF1 LPF2 ATT 1 & 2 AMP 1 DVD LFE80Hz 80–12 80–24 80–24 0 10 2 DVD LFE120Hz 80–12 120–42 80–24 0 10 3 Movie LFE80Hz 80–12 80–24 80–24 –3 10 4 Movie LFE120Hz 80–12 120–42 80–24 –3 10 5 Bypass THRU THRU MUTE 0 0 THXD THX DVD 80-12L 120-42 80-24L 0 10 THXF THX Movie 80-12L 120-42 80-24L –3 10 THXM THX Music 80-12L 120-42 80-24L 0 10 ATT1: Adjusts the level difference between LR and LsRs. ATT2: Adjusts the level difference between C and Bs. AMP: Corrects the LFE channel level. HPF1–3: Cut the low range so that the speakers’ supporting frequency ranges will not interfere with the sub- woofer signals. HPF1–2: Cut the high range so that the subwoofer’s supporting frequency ranges will not interfere with other speakers’ signals. Note: •If you select preset THXD or THXF, you cannot change the parameters. •If you select preset THXM, you can switch AMP between 10 dB and 0 dB. However, you cannot change other parameters. You can set the Bass Management parameters in the following ranges: Parameters Range HPF 1, 2, 3 THRU, 80-12, 80-12L, 80-24, 80-24L LPF1 THRU, 80-24, 80-24L, 120-42 LPF2 THRU, 80-24, 80-24L, MUTE ATT 1 & 2 0 to –12 dB (1 dB steps) AMP 0 to +12 dB (1 dB steps) The HPF 1, 2, 3, and LPF 1 & 2 values indicate a cut-off frequency and a filter response. For example, “80-12” means a cutoff frequency of 80 Hz and a filter response of –12 dB/octave. “L” means Linkwitz filter. Other filters are Butterworth. About the Presets (1) DVD LFE80Hz This is a preset optimized for DVD-Video production. The LFE playback bandwidth is set up to 80 Hz. When using this preset, we recommend that you use an external device to apply an LPF (fc=80 Hz, –24 dB/oct) to the LFE master source. To monitor audio on DVD-Audio or SACD discs, change the LFE level (AMP) and LPF (LPF1) to 0 dB and THRU, respectively, if necessary. The LFE output gain on some DVD players and decoders may already be set to +10 dB. To monitor the output from such devices, change the LFE level (AMP) to 0 dB. (2) DVD LFE12...
