STAGE1508 Thank you for purchasing the class D powered PFM1508. The STAGE1508 is a three-way self-powered two-channel sound reinforcement system. Based on a common subwoofer cabinet with a premium 15” woofer, and a pair of two-way satellite speakers with a 8” heavy-duty woofer . The PFM1508 features a bi-amped power section that provides250 watts peak power for the subwoofer and 100 watts peak power for each satellite speaker. Features 550W Active Two-Channel Three-piece Speaker System One shared Subwoofer cabinet which houses the inputs and power amps Two two-way Satellite speakers with speaker pole stand adaptors Subwoofer has 15” woofer, with 300W peak available power Satellite speakers have 8” woofer, 1” compression driver tweeter 200W peak available power to each Satellite speaker Protective slipcover with cable storage pockets and built-in Velcro retaining straps. Heavy-duty locking casters on Subwoofer cabinet for transport of system Four-pin twist-lock connectors on amplifier outputs and Satellite inputs Applications The STAGE1508 System has a variety of applications such as DJ, sound reinforcement, public address, or karaoke. It can even be used as a pair of powered monitors by turning the Subwoofer level all the way down. A typical signal source for the line-level inputs of the PFM1508 would be a sound reinforcement mixing console (mixer) or the output from a CD player, MP3 player or tape deck.

(8.2 kg) Dimensions (H x W x D): 17.55" X 9.45" X 9.84"(Upright, Includes feet) 1. IEC POWER CORD CONNECTION Accepts the included power cable for connection to a mains outlet 2. FUSE The unit is AC power line fuse protected from overloads and fault conditions with a slow-blow 4.0 Amp 250V fuse (100-120V) or 8.0 Amp 250V fuse(220-240V) 3. POWER SWITCH “POWER” Speaker is “ON” when the switch in the “1” position, use this switch to set the speaker power to ON or OFF. NOTE: When you shut down your equipment, turn off the speaker first. When powering up, turn on the speaker last 4. LINE VOLTAGE SELECTOR This switch sets the voltage line of you country (usually is set by factory and is not necessary to change it).The 115V setting is for mains line in the range of 100-120v~ and 230V setting is for mains line in the range of 220-240V~. WARNING: AN INCORRECT SETTING OF AC LINE VOLTAGE COULD DAMAGE SERIOUSLY THE INTERNAL ELECTRONICS! 5-6. SPEAKER OUTPUTS, Left & Right These are 4-pin twist-lock professional speaker outputs, with the drive signal on the pins 1+ and 1-. Minimum impedance load is 4 ohms, output is 300W peak available power, 150W continuous, into 4 ohms. Used to connect the supplied Satellite speaker systems, to the System electronics inside the Subwoofer. These outputs cannot drive any other speakers when the supplied 4-ohm Satellites are used. They have been high-pass filtered at 120 Hz, using a 24 dB/octave roll-off. 7-8. INPUTS, Left & Right The line-level input is of the medium impedance balanced type. Jack (7, 8) is a combo female XLR and 1/4" TRS connector. 9. INPUTS, Left & Right A pair of RCA jacks (9) wired in parallel with the above listed inputs. The top or WHITE jack is the Left channel input, and the bottom or RED jack is the Right channel. Used to input a signal，from a consumer type signal source, such as a CD player, Cassette deck or Radio. 10. INPUTS, MIC Jack (10) is a female XLR for MIC input. 11-12. THRU OUTPUTS These male XLR jacks provide a means to send the input signal on to another device, or to daisy chain the STAGE1508 into another STAGE1508 unit. These can also be used to connect a STAGE1508 system for mono input operation using a short XLR (or 1/4” phone jack) cable from the Thru jack to the other channel input jack. For instance, you can run a Mono signal to the Left channel input (7), then run a short XLR cable from the Thru jack (11) to the input jack of the Right channel (8). 13. POWER / LIMIT LED It is on, or GREEN, when power is applied. It turns RED when any of the power amps soft limiting, or when the input channel is overloaded. 14. MASTER SYSTEM LEVEL Controls the gain (level) of both the Left and Right ，input channels at the same time, of the entire powered stereo speaker system. It is used to directly set the system output level for a given input signal. It turns the level of both the Subwoofer AND the Satellite speakers up or down at the same time. Clockwise rotation increases the level, counter-clockwise rotation reduces it. The sound is full OFF when the control is rotated full CCW. When set to a 12 o’clock position, the gain will match well with many mixers and sound sources. 15. LINE LEVEL This knob is only for JCAK (7, 8, 9) input volume to be adjusted. 16. MIC LEVEL This knob is only for JCAK (10) MIC input volume to be adjusted. 17. BALANCE CONTROL This knob is only for satellite left or right balance volume to be adjusted. 18. SUB LEVEL Controls the gain (level) of the Subwoofer ONLY, allowing the balance between the bass and the rest of the sound to be adjusted. 19. PHASE SWITCH Change the PHASE of the Subwoofer ONLY. Push IN the woofer polarity will reverse 180°.
