Connections
1.Before plugging in the power cord, make sure that the VOLTAGE SELECTOR (41) switch is set to the correct voltage.
NOTE: This product is double insulated and not intended to be grounded.
2.Make sure that the POWER (34) switch is in the off position. The POWER LED (35) will be off.
3.The PDM-24s is supplied with 3 sets of amp output jacks. The MAIN OUTPUT (43) jacks are unbalanced and used to connect to your main amplifier. The REC OUTPUT (45) jacks can be used to connect the mixer to the record input of your recorder enabling you to record your mix. The BOOTH OUTPUT (44) jacks allow you to hook up an additional amplifier.
4.The MIC 1 (1) input (found on the front panel) accepts a 1/4" or XLR connector. The MIC 2 (57) input (found on the rear panel) accepts 1/4" connectors. All accept balanced and unbalanced microphones.
5.On the rear panel are 3 stereo PHONO/LINE (49, 52, 55) inputs and 5 stereo LINE (46, 47, 48, 51, 54) inputs. The PHONO/LINE SWITCH (50) enables you to set the (49) input to Phono or Line. The
PHONO/LINE SWITCH (53) enables you to set the (52) input to Phono or Line. The PHONO/LINE SWITCH (56) enables you to set the (55) input to Phono or Line. The phono inputs will accept only turntables with a magnetic cartridge. A GROUND SCREW (58) for you to ground your turntables is located on the rear panel. The stereo line inputs will accept any line level input such as a CD player, a cassette player, etc.
6.Headphones can be plugged into the front panel mounted HEADPHONE (40) jack.
7.The PDM-24s comes with a front panel BNC LIGHT (33) jack. This jack is for use with a gooseneck light like the Gemini GNL-700.
Using the Ground Lift Switch
Depending on your system configuration, sometimes applying the ground will create a quieter signal path. Sometimes lifting the ground can eliminate ground loops and hum to create a quieter signal path.
1.With the mixer on, listen to the system in idle mode (no signal present) with the ground applied (the GROUND LIFT SWITCH (59) in the left position).
2.Then turn the power off before moving the GROUND LIFT SWITCH (59). Lift the ground by moving the GROUND LIFT SWITCH to the right, turn the power back on and listen to determine which position will provide a signal devoid of background noise and hum. Keep the GROUND LIFT SWITCH in the ground position if the noise level remains the same in either position.
CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER MIXER IN ANY WAY. TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.
Operation
1.POWER ON: Once you have made all the equipment connections to your mixer, press the POWER SWITCH (34). The power will turn on and the POWER LED (35) will glow RED.
2.CHANNEL 1: Switch # (9) allows you to select the PHONO 1/LINE 1 (55) or the LINE 2 (54) input. The CHANNEL SLIDE (10) controls the input level of this channel.
3.CHANNEL 2: Switch # (11) allows you to select the PHONO 2/LINE 3 (52) or the LINE 4 (51) input. The CHANNEL SLIDE (12) controls the input level of this channel.
4.CHANNEL 3: Switch # (13) allows you to select the PHONO 3/LINE 5 (49) or the LINE 6 (48) input. The CHANNEL SLIDE (14) controls the input level of this channel.
5.CHANNEL 4: Switch # (15) allows you to select the LINE 7 (47) or the LINE 8 (46) input. The CHANNEL SLIDE (16) controls the input level of this channel.
6.CROSSFADER SECTION: The CROSSFADER (18) allows the mixing of one source into another. The PDM-24s features an assignable crossfader. The ASSIGN (17, 19) switches allow you to select which channel will play through each side of the crossfader. The ASSIGN (17) switch has 5 settings (OFF, 1, 2, 3 or 4) and allows you to select channel 1, 2, 3 or 4 to play through the left side of the crossfader. The ASSIGN (19) switch has 5 settings (OFF, 1, 2, 3 or 4) and allows you to select channel 1, 2, 3 or 4 to play through the right side of the crossfader. With the ASSIGN switch in the off position, that side of the crossfader will be inactive. The CROSSFADER (18) in your unit is removable and if the need arises can be easily replaced. Crossfader units are available in three varieties. Part # RF-45 (which is identical to the crossfader supplied with the mixer) has a 45 mm travel from side to side. Part # RF-30 is available with a 30 mm travel distance. Also available is the PSF-45
