They do not affect the monitor section, or MAIN 2. MAIN OUT 1&2 ST/MONO @) and ® Both MAIN OUT 1 and MAIN OUT 2 can be made mono. If you are using stereo sound systems (discrete left and right channels), then set the appropriate switches to ST (stereo). If you are using the left and right outputs to drive separate mono systems, set the appropriate switches to MONO (mono). MONO OUT 1 PRE/POST (§) When this switch is set to PRE, the MAIN 1 fader and master EQ controls will not affect MONO OUT 1. When it is set to POST, sound will be sent out of MONO OUT 1 after going through the MAIN 1 fader, and the master EQ controls. (This always happens for MONO OUT 2). MAIN OUT 2 MIX/SOURCE @) When this switch is set to MIX, MAIN OUT 2 will output the same as MAIN OUT 1, except without the master EQ controls. When it is set to SOURCE, MAIN OUT 2 will only output sound coming from the SOURCE/ BGM section. This will be affected by BGM mute, but will not be affected by “ducking”. 13 System examples Wedding ceremony Stage monitor speakers Main speakers Foldback amp Power amp oooo Other microphones/electronic instruments OOOO ?

Notice the following points: • The PAD switch for the radio microphone is set to 20 dB. The PAD switches for other microphones are set to 0 dB • The CD player provides the background music before, after and during certain parts of the ceremony. • The cassette deck has a recording of a wedding march, to be played as the bride and groom leave. • So that the background music stops automatically when the wedding march plays, switch BGM MUTE (on the lower front panel) on. • Additional speakers (e.g. for the foyer) can be connected to MAIN OUT 2. • The sound operator can switch between the two video cameras with the SOURCE 3 A/B switch on the front panel. The picture will be recorded with stereo sound, and can be monitored through the video monitor. ▼ On the front panel (not pictured): (a) BGM mute is on. (b) Mies are set to SPEECH if used for speech, and VOCAL if used for singing. (c) Compression and/or noise gating can be used if desired. (d) Source muting can be used if people will be speaking over the BGM. 14 System examples Business conference Main speaker L Stage monitor speaker L Foldback amp Stage microphones Power amp OOOO a OOOO MONO OUT 1&2 OOÔÔ Power amp 2 £ о П O O D a OO "Г Main speaker R Stage monitor speaker R 1Ж1 OOOO OOQQÔOOOOOOOO OOOO Tape deck Д“* » О IXI IXI О о ÖÖoÖÖ ( £ oooooo Video A Video out CD plâyer Audio out Video B Speakers for lobby/foyer i i ^ j|—|—j []' 1 ! 1 i ! ! ^ ~ *""o o| An example of a system setup for a business conference is shown. Notice the following points: • The PAD switches are set to OdB when using normal (not radio) microphones. • For video presentations, the sound operator can switch between the two video players. As the sound from the videos is also going through SOURCE 3 A and B, the sound will be switched too. • If the presenter wishes to speak while the video is playing, source muting can be turned on, so that the presenter will be heard more clearly. • An audio recording of the entire conference is made by the cassette deck connected to the REC OUT jacks. • The speakers connected to MAIN OUT 2 could be positioned in the foyer, or lobby. T On the front panel (not pictured): (a) All microphone channels are set to SPEECH (b) Noise gating is recommended and compression is optional. (c) It is possible to stop sound from the microphones going to the second pair of speakers, by switching the MAIN OUT 2 MIX/SOURCE switch to SOURCE. In this case, the BGM will still be sent. 15 Specifications Total harmonic distortion Frequency response Hum & noise*1 (Rs=150 Q, Input gain=max, Input pad=0 dB, Input sensitivi-ty= -80 dB (20 Hz ~ 20 kHz)) Crosstalk (@ 1 kHz) Maximum voltage gain Mic Input channels (CH 1-6) Source input channels (CH 1-3) BGM input channel Digital effects unit Compressor Source mute MAIN 1 EQ controls Less than 0.1 % 20 Hz~20 kHz @ MAIN OUT+14 dB into 600 Q @ REC OUT-IO dB into 47k Q others +14 dB into 10k Q (Master fader nominal, one channel fader nominal) +1, -3 dB 20Hz~20kHz @ MAIN OUT+ 4 dB into 600 Q @ REC OUT-IO dB into 47k Q others +4 dB into 10k Q -97 dB residual output noise -128 dB equivalent input noise -64 dB (68 dB S/N) MAIN OUT (Master fader nominal, one channel fader nominal, others minimum) -80 dB (84 dB S/N) MAIN OUT (Master fader nominal, all channel faders minimum) 70 dB adjacent input channels 70 dB input to output*2 84 dB MIC IN to MAIN OUT, MIC IN to MONO O...
